Troubleshoot A Fujifilm S5000

When viewing content from your camera on a computer, connect the devices using a USB cable.

Japanese camera maker FujiFilm's S5000 series of cameras are currently available in the S5700 and S5800 models that carry the FinePix brand. Problems with the cameras can involve shooting, playback and power supply issues related to the batteries. Complications also can occur when erasing images or connecting the camera to a television or a computer for playback or to transfer files. Problems with the FujiFilm FinePix S5000 series can be corrected with a few troubleshooting steps.

Instructions

1. Charge the batteries if the camera won't work at all. The zoom lens failing to extend is a dead giveaway that the camera is about to crash and needs charging. Charge the batteries at this point, even if the camera's screen comes on.

2. Insert a replacement memory card if the camera won't record images. The cards can fill up. Keeping a few extra cards handy will allow you to keep shooting.

3. Allow the FujiFilm FinePix S5000's flash to charge between shots if the camera won't capture images and you've been using the flash. The flash charging is automatic, but it takes a moment.

4. Move the mode switch to the arrow icon position if the camera won't play back images. The arrow icon indicates Playback. The camera won't capture images in the Playback position.

5. Connect the camera to a television or computer if you find it difficult to see the images properly on the small screen. The cables are included in the box. In the case of the television playback, attach the yellow plug to an input jack on the television; set the television's Input setting on the remote control to match the jack you used. In the case of a computer, use the USB-ended cable. Simply connect the camera and follow the on-screen prompts.

What Is A Rangefinder Camera

Rangefinder camera

"Rangefinder" refers to the type of optics used in a camera. Popular in the '30s, '40s and 50s', rangefinder cameras were essentially replaced by today's single-lens reflex (SLR) cameras.

Origin of the rangefinder

Rangefinder camera

The rangefinder camera was introduced in 1932. It was largely responsible for making photography popular among non-professionals since earlier cameras where much larger, significantly heavier and used optic systems that projected inversed images prior to capture.

Two images become one

Today's SLR cameras offer 'through the lens' or TTL image viewing. Rangefinders don't have TTL image viewing. They use a different type of viewing system.

On a rangefinder, you look at the image through the viewfinder, but the image comes into the camera from a different window. The result is that you see two images: one slightly imposed on the other. The camera is in focus when you turn a focus ring around the lens until two images line up.

The focus from a rangefinder camera is incredibly precise, which is why it remains a favorite among professional photographers---even those who shoot film or digital SLR 35mm or medium format cameras.

Photocomposition

Since the perspective of shooting with a rangefinder is different than from a SLR or other TTL camera, it may take some time to adjust your photocomposition technique. It may require more skill---or at least a finely honed "eye"---to properly frame an image with a rangefinder.

Benefits

The difference between a good picture and a great picture is timing. Even a millisecond of shutter lag can cause you to miss a great shot. Rangefinders don't use the same type of mirror optics as SLR cameras do. With no moving mirror, there's no shutter lag.

Rangefinders can offer a higher quality photograph. Without the mirror, the lens can get closer to the camera's image plane. The image plane is where the magic of creating a photograph happens. And because there's no moving mirror, there's less likelihood of blur created by the mirror movement at slower shutter speeds.

Rangefinder cameras are smaller and lighter. Since they have less glass, the cameras weigh less than SLRs. The cameras perform better with smaller lenses, which also means less weight.

Disadvantages

With rangefinder cameras, what you see in the viewfinder and what you capture through the lens are two different things.

Bigger lenses may block or interfere with the viewfinder. This means that you won't want to shoot with most of the larger telephoto and fisheye lenses. Zoom lenses don't work well on rangefinder cameras either.

Range finders aren't designed for macro or super close-up images. They shoot best at medium and long distances.

Troubleshoot A Sony Handycam Dcrdvd201 Lcd

The Sony Handycaom DCR-DVD201 is a standard definition-based video camera that records all content onto an inserted miniDVD. To view what you recorded, look at the small, color viewfinder or flip out LCD monitor. If the LCD monitor is not working correctly, though, you do need to troubleshoot the issue.

Instructions

1. Fully charge the battery on your Sony Handycam. If the battery is about to fail, the camcorder shuts down different features, including the LCD monitor.

2. Fully flip out the LCD monitor. If the monitor is only partially open, it won't display the content.

3. Turn off the camera and remove the battery. Leave the DCR-DVD201 off for a few minutes, then reconnect the battery and power on the camcorder. Once the camera is on, the LCD monitor should work correctly.

4. Press the "Menu" button on the side of the digital camcorder. Occasionally, when the monitor is left open for an extended time without being used, the LCD screen shuts down. Pressing the "Menu" button brings the video information back onto the screen.

The History Of Infrared Cameras

Infrared cameras are often used as security devices.

Infrared cameras use film or image sensors that are sensitive to infrared light. Infrared light bands are between 700 and 1,400 nanometers on the spectrum and are not visible to the human eye. Infrared cameras are able to capture images that other cameras cannot, and are capable of taking photographs and recording video in total darkness.

Discovery

Infrared photography was not possible at the beginning of the 20th century because film relied on silver halide emulsions -- a substance incapable of capturing infrared light. In October 1910, Robert W. Wood used an experimental film that required very long exposures and published the results in "The Century Magazine." These photographs were the first infrared pictures taken by an infrared camera.

World War I

The United Stated began developing infrared-sensitive photographic plates for use in World War I. Infrared cameras were very useful in spectroscopic analysis and aerial photography. Dyes such as cryptocyanine could be added to penetrate through haze and reveal the positions of enemy troops. Infrared cameras were still only able to capture black and white images at this stage of development.

Popularity

In the 1930s, infrared film became commercially available to the public and it quickly became popular with photography enthusiasts. Major newspapers and filmmakers began experimenting with infrared photography to increase interest in their product. In the 1940s, Kodak introduced the first false-color infrared film called Kodak Ektachrome, which attempted to mimic natural colors. Because infrared cameras produced unexpected colors and unusual results, it skyrocketed in popularity with the 1960s psychedelic culture, often appearing on the album covers of popular musicians.

Today

At the turn of the 21st century, a large percentage of infrared cameras were digital and used primarily for security purposes -- due to their ability to detect images in darkness. Although public interest in infrared imaging seems to have waned, many digital cameras are still on the market capable of shooting infrared photography.

Unlock The Password On Nokia Cell Phones

If you have purchased a Nokia cell phone on a contract with your carrier, chances are that your carrier has locked the phone so it works only with its service. If you want to switch to another carrier and use a SIM of your choice, you have to "unlock" the phone using a password or an unlock code. Although unlock codes can be obtained for free from many websites, they do not guarantee code accuracy. If you try inaccurate codes more than five times, your phone will be hard locked, after which it can only be unlocked by a professional.

Instructions

1. Unlock the cellphone using the website The Travel Insider. After you sign up, you will be taken to a page where you can purchase the code using your credit card or PayPal account. Depending on the cell phone you have, you may be charged anywhere between $5 and $25, as of August 2010.

2. Use the website Express Unlock. Provide information including the phone's IMEI number. The website charges $4.95 as of August 2010. You will receive a guaranteed unlock code via email along with instructions for entering it.

3. Obtain the code using the website Nokia Free. Upon submitting your details, you will receive a couple of passwords that you can try. This is a free service, and the website doesn't guarantee success, but it may be worth a shot. Do not try more than five inaccurate codes, as that will cause your phone to lock permanently.

4. Enter the code in this format: #pw+CODE+1# (your phone should not have a SIM card at this point). If the code turns out to be inaccurate, you will be asked to try again. Once you enter the correct code, you will see the message "SIM Restriction Off" on the phone display.

Adjust The Focus On A D700

Focusing in photography is essential to separating an image's subject from its context. Depending on the situation, photographing certain subjects may be best done with the automatic focus settings of a camera or manual focus. Nikon employs several focusing features in its Digital SLRs so that camera owners can have more control over focus. The Nikon D700's focal versatility comes in the form of autofocus, adjustable autofocus and manual modes. Users who master these modes will increase the chances of composing outstanding photographs with sharp looking subjects.

Instructions

Autofocusing

1. Ensure that the switch on the D700 camera lens labeled with an "A" and "M" is set to "A."

2. Find the focus mode switch on the front of the D700's body, to the left of the lens. Notice the three focus mode options: "M","S" and "C." Set the switch to "S" for single-AF mode. Single-AF locks the focus into place after finding the appropriate focal point. Set the switch to "C" for continuous-AF mode. Continuous autofocus adjusts and tracks focus as the subject moves. Single-AF mode is ideal for posing shots while continuous-AF mode is ideal for action and sports photography.

3. Toggle the AF sensor switch, located directly to the right of the LCD screen to determine how the autofocus sensors detect a subject. Set the switch to the blank white icon for the camera to chose focal points automatically. Set the switch to the icon with the box surrounded by four spots to be able to choose the focal point, but allow the camera to adjust to moving subjects. Set the switch to the icon with the solitary box to be able to chose the focal point manually with no help from the camera.

4. Turn the dial surrounding the directional pad on the back of the camera until the white hash mark and the white dot are aligned. Look through the viewfinder and use the directional pad to move the focus sensor to different points in the frame. This step is unnecessary when the AF sensor switch is set to the blank white box.

5. Press the D700's shutter release or "AF-ON" button to activate the autofocus. Continue looking through the viewfinder to ensure the camera is properly focusing. Press the shutter release completely to take the picture.

Manual Focusing

6. Set the switch labeled with and "A" and "M" to "M" for manual mode.

7. Look through the viewfinder and locate the subject of the picture.

8. Turn the focus ring, surrounding the camera lens, until the subject is clear and crisp looking.

9. Press the shutter button completely to take the picture.

Parts Of A 35mm Camera

Without pictures, most of our memories would become hazy, if not totally forgotten. Pictures allow us to capture the moments we treasure just as they are, giving us a welcome reminder of the past for generations to come. The 35mm cameras have taken millions of pictures over the years, giving people exactly what they want - captured memories. But the camera is not just a box with a button on it. There are parts of a camera that make our pictures perfect, and without these parts our memories might be lost.

Lens/Pentaprism

A 35mm camera has single-lens reflex (SLR) to help focus in on the image. This lens can be adjusted to bring the image into view, making it smaller or larger. The lens is a bent piece of glass that allows the beams of light to bounce from the object and then be recaptured on the film in the camera to form an image.

The pentaprism is located inside the lens. It is a prism mirror that helps avert beams of light within a 90 degree angle.

Shutter

The shutter protects the lens when the camera is not in use. This shutter opens up automatically when the camera is turned on.

Flash

The flash, which is built directly into a 35mm camera today, is there to give extra lighting, so that the image can be captured more clearly. Flashes are mainly used indoors where the lighting is not as good or outdoors when it is cloudy or nearing dusk.

Viewfinder and Focusing Ring

The viewfinder is a little window built inside the camera where you look through to find and focus in on the image that you want to shoot. The focusing ring helps to bring the image into focus, giving you a clear picture of the image. The focusing ring allows the lens to move back and forth so that this clear picture can be obtained.

Film

The film is placed inside the camera and is set by an ISO indicator, which sets the speed of the film. The lower the speed of film, the more light it takes to capture a clear image. The film moves from frame to frame by a film advancer lever. Some advancer levers are manual, which are located on the outside of the camera, and some are built in, and auotmatically move the film from frame to frame.

Rewind Release

The rewind release is an automated system that rewinds the film within the camera, once it has been used, protecting it from the light before it it taken out of the camera.

Tune An Rca Tv Antenna

If you've decided to skip the large monthly payments often associated with cable and satellite programming, you may want to just use a television antenna. An antenna can pull in your local broadcast programming. Although the exact position of the antenna changes for each channel, tuning an antenna, whether an RCA model or another type, takes only a moment or two.

Instructions

1. Check your television's user manual to see if the TV is digital or analog. If the TV is analog, you must use a digital-to-analog converter box to switch the audio/video signal from digital to analog. If you don't, your television will be unable to receive any of the broadcast programming.

2. Connect the coaxial cable from the antenna into the "In" port on the television. If you must use a digital converter box, plug it into the "In" port on the converter. Next, hook up the stand-alone coaxial cable and plug it into the "Out" port of the converter box, then insert the other end into the "In" port on the TV.

3. Turn on the TV, the converter box (if required) and the RCA antenna. The antenna has two movable parts: a large, circular hoop and a standard "rabbit ear" setup.

4. Move the rabbit ears around to receive stations under channel 20. Rotate the large circular hoop to obtain a better signal for all stations above channel 20. The exact position of the RCA antenna will vary slightly depending on the station whose signal you are attempting to receive.

Improve Shortwave Reception In A Grundig S350

A popular piece of technology for those living abroad, shortwave radios give users the ability to listen to radio broadcasts from around the world. Operating between the frequencies of 350 KHz and 30,000 KHz, shortwave radios capture radio signals as they rebound off the earth's ionosphere. And while you can't control the atmospheric conditions that dictate the strength of shortwave signals, there are a few things that you can do to improve shortwave reception on your Grundig S350.

Instructions

1. Search for a shortwave station with your radio set to the "SW2" position for the best reception in the daytime. Search the "SW1" bands for night reception.

2. Fine-tune your station selection using your S350's inner tuning knob. Watch the signal strength indicator on the S350's display as you tune your station.

3. Set the "Band Width" control switch to "narrow" to improve your Grundig's reception of shortwave stations. You can also turn on the "SW LPF" switch to lower the background noise on your stations.

4. Connect a 500-ohm shortwave antenna to your S350 to improve its shortwave reception. Connect your antenna to the "AM/SW ANT" port on the back of your radio, and connect the antenna's ground wire to the black "GND" port--press the tabs outside the ports to open the ports.

Creative Do It Yourself Projects

Get ready to paint.

If your home needs a pick-me-up, consider several low-cost, creative, do-it-yourself projects that will add pizazz to your house, inside and out. A project does not have to be big to create an impact that will wow guests. With a little bit of paint, a few supplies and old-fashioned elbow grease, you will be on your way to adding new focal points to your home.

Fold It Up

A folding screen made from hollow-core doors is a work of art in addition to a functional piece of furniture. Purchase three hollow-core doors (lightweight, hollow doors without holes) from any large hardware store. Add two or three heavy-duty hinges to each side of the doors and paint the doors to match your decor. Tah-dah! Instant art and a useful room divider/screen combined.

Trellis Art

Paint a trellis that has an interesting shape.

Change a trellis into a work of wall art. Buy a trellis that has a unique shape and -- even better -- includes some metal elements (for added interest). Paint the wood on the trellis with black paint and screw two large, heavy-duty eye hooks onto the horizontal side of the trellis. Add a length of eight large links of chain, also painted black, to the eye hooks. Hang the painted trellis by the chain links onto a large, empty wall that needs jazzing up. Use a wrought-iron curtain rod with interesting finials to hang the chain from.

Frame It

Create visual interest around a boring ceiling fan or light fixture by placing a large picture frame around it, mounted to the ceiling. Purchase a large frame, at least 22 by 26 inches, and paint or texture it with colors complementary to your decor. Separate the frame at one corner in order to slide it over a light fixture or ceiling fan and reassemble it when it is installed. Use finishing nails to attach the frame to the ceiling, then glue it in place. Hold glued the frame pieces in place until they dry with painter's tape, then remove. Additionally, paint the ceiling area within the frame with a metallic paint that matches the frame for artistic flair.

Ladder for the Birds

Use a variety of birdhouse styles.

Paint a old ladder, 6 feet long or less, any color that suits you for a project destined for the outdoors. Set the ladder in an out-of-the-way place in your backyard and place birdhouses of different styles on each ladder rung. Anchor the birdhouses using a hand-held tube of heavy-duty glue such as Liquid Nails brand adhesive. You have just created a home for the birds and an interesting view for guests.

Scan 2 Inch Slides

Scanning slides, even odd-sized slides, is the best way to convert them to digital files.

Scanning slides is good way to convert your archive of photographic slides into digital files. Most dedicated film scanners come with a number of different carrier trays. While 35mm slides may be the most common type of slide film that was produced, there were also other sizes and formats produced over the years. One such format was a larger 2 x 2-inch slide. These slides may or may not be mounted into slide holders. Either way, you can scan these slides the same way you would scan 35mm slides, it will just take longer per slide.

Instructions

1. Turn on your computer and dedicated film/slide scanner. Open up the scanner's software on your computer.

2. In the preference or option section of the scanner software, designate the type of slide you are about to scan as being a 2 x 2-inch slide.

3. Create a new folder in your computer and designate this folder as the location where your scanned slides will be saved.

4. Prepare your 2 x 2-inch slides to be scanned by gently cleaning them using an anti-static cloth. This cloth will remove any dust from the slide and help prevent dust collecting onto the slide during the scanning process.

5. Place the slides into the slide carrier and secure them in place by closing the top of the slide carrier.

6. Insert the slide carrier into the film scanner, and press the "Start" button either on the scanner or in the software.

What Is A Camera

What Is a Camera?

A camera is a device that is used to transfer an image onto either a sheet of film or a space on a digital hard drive. It does this by collecting light that is reflected off an object and then creating a copy of the image on whatever storage device the particular camera uses. There a number of different of different types of cameras, some of which capture still images while others focus on moving images.

History

The precursor to the modern camera is known as the camera obscura, which was described in the 11th century in the "Book of Optics," written by Ibn al-Haytham. This was able to focus light and emit an image of what is outside of the device. In 1685, a portable camera obscura was created. In 1826, the first camera that was able to create a permanent photograph on film was created. Since then, cameras and camera technology have developed in amazing leaps and bounds. Video cameras were created, as were digital cameras, which made taking pictures cheaper and more efficient.

Types

The most common type of camera today is the traditional film camera. These use rolls of black and white or color film and expose a single image onto a piece of film screen that can later be developed. Digital cameras are a more recent invention that increases the number of pictures that can be taken by uploading images onto a memory card rather than onto film. Video cameras are able to take multiple still shots at high speeds in order to create a moving picture. These also come in film and digital varieties.

Identification

While the shape, size, and color of cameras vary greatly, they can all be identified by the same components. A viewing lens is seen on one end that may or may not have padding over it, depending on the size of the camera. On the opposite end is a wider lens that collects light to form an image on film or through digital technology located inside the body of the camera. A flash is found on the front of camera or extending above it. Most cameras also have a shutter button on the top right of the camera body; this is used to take the photos.

Function

Cameras have an aperture lens on their front end with a convex lens that collects light bounced off and created by objects in front of it. This light creates an image in much the same way as a telescope allows people to view objects. When the shutter button on a camera is pressed, the image of a single moment is taken and then transferred onto a sheet of film or onto a digital card. Video cameras take thousands of stills as long as they are on, which create a moving picture, so no shutter is needed. The lens of a camera can be shortened or extended to zoom in on images and turned to focus on them.

Significance

Cameras are very significant inventions that have allowed people to capture images for personal and professional use. They are important in the preservation of memories for friends and families and have led to the widespread use of photo albums as a family tradition. In the professional world, they are used for documentation purposes and they have also been used by artists to create creative images for display in galleries and photo books.

Tell What Class A 8gb Sdhc Sandisk Ultra Ll Card Is

With the new speed classes, it's easy to figure out the transfer speed of any SD card.

In 2006, the SD Card Association came out with SD card Speed Classes, a new way of classifying the read/write speed of SD cards. If you know interpret the speed classes, figuring out the read/write speed of a certain memory card is a breeze. This makes choosing a card simpler, as well giving you the assurance that you have the right card for your camera.

Instructions

1. Pick up the SDHC card and turn it so that you can see the front of the card. The back is the blank side with the metal receptors in it, and the front is the side of the card that has any sort of writing or pictures on it.

2. Look near the center of the card. You will see a small number enclosed in the letter "C." This number corresponds with the number of Megabytes that the SDHC card is able to move from one place to another every second, represented by the unit "Megabytes per second," or MB/s. This rate is often called the memory card's transfer speed.

3. Look to see what number is marked on your SDHC Ultra II card. This number represents the Speed Class of the memory card. For example, a symbol with the number "4" enclosed in the letter "C" would mean that your memory card is Class 4. This would also put your card at a minimum transfer speed of 4 MB/s.

Get More Channels Out Of A Converter Box

Digital cable boxes are used by cable TV providers to offer more channels than can be offered over a traditional coaxial cable connected directly to your TV. In addition to having a digital cable box installed in your home, you also need to subscribe to digital cable programming in order to take full advantage of all that your cable box has to offer. If you wish to receive more channels than you are currently receiving through your digital cable box, it is simply a matter of calling your provider and scheduling an upgrade, but there are a few important things to consider before.

Instructions

1. Reset the cable box by unplugging its power cord for 30 seconds and plugging it back in. Certain technical problems on a cable box can cause channels to go missing even if you subscribe to them, so the first step in getting more channels on your cable box is to reboot the box fully to restore channels that might have temporarily gone missing.

2. Determine what channels are offered by your cable provider. If you already subscribe to every channel offered by your provider, there will not be any channels to which you can upgrade your cable box. Your cable provider can tell you what channel upgrades are available as well as the cost.

3. Upgrade your cable service. Once you have determined what channels you wish to add and what budget you have, inform the cable provider and he can "assign" the channels to your cable box. Typically, this does not require a technician coming to your home but can be done remotely by sending a signal to your cable box. A reboot might be required after the box receives the signal in order for the new channels to show up.

Save Money On Prepaid Cell Phone Cards

Prepaid cell phone services provide the convenience of wireless phones for students, people with credit problems and folks on a tight budget. Most major cell phone providers have prepaid services and pay-as-you-go plans. In order to save money when purchasing or refilling cell phone cards, consider the following tips.

Instructions

1. Purchase a higher denomination cell card. Most companies offer free minutes with the purchase of a more expensive cell card. A $100.00 cell phone card may give you extra minutes and expire later than a $25.00 cell card.

2. Determine what services you will need and go with a cell phone provider that includes them in prepaid minutes. Some prepaid services offer text messages, Internet access, international calls and roaming fees as part of the prepaid package. Check on the services you will need before you decide on a provider.

3. Look for free calls. Paid services allot free minutes during nights after a certain time and on weekends. Look over prepaid plan listings and see which ones provide free calls at certain times to save on calls.

4. Add refill minutes through the wireless provider's website or add them via a toll-free phone number. This is often cheaper than buying a brand new card.

5. Budget your cell phone time. Use your prepaid cell card for important, emergency or brief social calls. Save long gabfests for your landline. Cell phone cards are an inexpensive alternative to regular cell plans, but you don't want to run out of minutes and have to refill when you need to make an important business call.

Save A Dead Car Battery

A dead battery can be an inconvenience, but there is a chance you can bring it back to life.

Car batteries can last for several years, but if they're not properly maintained, they can die on you, leaving you with no way to start your vehicle. This typically happens at the worst possible time, leaving you stranded with no way to get you to your destination. Most times, when a battery is dead, there isn't much chance of recovery. But sometimes, there is a chance that you can revive the battery one last time to be able to get your vehicle to a parts store or repair shop to get a new battery.

Instructions

1. Open up the hood of the vehicle. Put on rubber gloves on. Remove the negative terminal on the battery using an open-end wrench, then repeat for the positive terminal on the battery.

2. Locate the rectangular plastic caps on the top of the battery, which are used to check the fluid levels in the battery. Remove the plastic caps using a flathead screwdriver to pry them off.

3. Locate the circular cells underneath the caps and the marks in the plastic which indicate the fill mark. Pour distilled water into each of the cells until the level reaches the fill line. Reinstall the plastic caps.

4. Connect the black alligator clip from the battery charger to the negative terminal of the battery and the red alligator clip from the charger onto the positive terminal. Adjust the settings on the battery charger so the output is a low amp rating, preferably under 4 amps. Turn on the charger and allow the battery to charge for four hours.

5. Reconnect the positive terminal onto the battery and then the negative terminal using an open-end wrench. Disconnect the alligator clips and attempt to start the vehicle. If it does not start, try charging the batteries for another four hours and then try again.

Save A Corrupt Sd Card

SD cards, short for "secure digital" cards, is a flash media format commonly used in cameras and smartphones. SD cards can get damaged or corrupted for a number of reasons -- including removal of the card when it is being written to, or a power outage during reading or writing. Fortunately, most of these types of problems can be fixed.

Instructions

1. Download an appropriate data recovery program, as you may need to recover important files before reformatting the SD card. Choose one designed for recovering data from corrupted memory cards. Most data recovery programs use a simple wizard-driven interface which will guide you through the recovery process.

2. Insert the SD card into your computer's card reader. Open the Start menu and click "Computer" in the right-hand side of the menu. Right-click on your SD card in the Explorer window. Choose a format and be sure "Quick format" is selected. Leave everything else at the default settings. Click "OK" and wait for the card to be formatted.

3. Go to sdcard.org if the format did not work. Download the SD card formatter from the site and run it. Follow the on-screen prompts which walk you through the process. This program works in most cases, but if it does not, your SD card may be permanently damaged and in need of replacement.

Batteryoperated Homesecurity Cameras

Technological advances have changed how everyday life operates and also how that life is monitored. Using batteries to power security cameras has evolved the monitoring options in order to ensure safety and protection for home owners.

Function

Battery-operated home security cameras use rechargeable battery. Some cameras can plug directly into a USB and charge, while others charge through an AC outlet. Some cameras operate on standard AA or AAA batteries as well. The cameras typically run Wi-Fi technology in order to program to a receiver, but cameras can also be automatically assigned an IP address and are allowed access through an Internet network.

Types

Wireless home security cameras can come equipped as a standard lens and antenna, or be disguised as something else so that intruders and guests do not know it is there. Some of the more popular designs include a boom box, VCR, alarm clock, table lamp, tissue box and a coffee maker.

Features

Battery-operated home security cameras have flexible features depending on each situation. Simple cameras feature black and white footage, average quality and a short wireless span. More advanced cameras feature wireless capabilities, color options and night vision. Expensive cameras can transmit data through multiple walls and over the Internet.

Benefits

The use of wireless home security cameras has many benefits for the home. The cameras offer surveillance in case of an intruder and if there is one, the video footage is used as evidence in capturing the intruder. The cameras can also be used with suspicion, either with spouses, a nanny, or another member of the home. The cameras last long and they can be placed virtually anywhere because they are wireless.

Considerations

The use of batteries in a wireless camera can limit the camera's use. A dead battery can result in the loss of recording time and potential footage. Most of the cameras have a back-up port in case they need to be plugged in and charged. In some cases, the WiFi connection may interfere with other wireless devices, but improvements have eliminated many of these shortcomings.

Maintain An Inkjet Printer

Just like any other computer peripheral, you'll want to perform some routine maintenance operations on your inkjet printer to maintain print quality and prolong its life. Here are a few quick measures to take to help maintain an inkjet printer.

Instructions

1. Replace ink tanks. Your computer will let you know when you are running low on ink. Keep printing as normal, but have a spare tank on hand for the corresponding color. Wait until the tank is empty before you replace the tank.

2. Check nozzles. This can be done by running a self-test (see manual) or through your computer.

For Windows, click Start | Control Panel | Printers and then right click your printer and select properties. Select the maintenance tab and choose nozzle test.

For Macintosh, from any program that prints select File | Page Setup then click "Utilities" and select "Test print" from the drop down menu. Click "Nozzle Test." On the test page, look for unevenness in color or missing lines. These indicate that the print heads need cleaning or alignment.

3. Clean print heads. Access the printer maintenance page as in step 2 and select the "Cleaning" option.

4. Align print heads. Access the printer maintenance page and select the option for "Print head alignment."

5. Manually clean the printer. Make sure the printer is unplugged. Open the printer and use a dry lint-free cloth to gently wipe away any accumulated dust or stray drops of ink.

6. Update drivers. If your printer is a bit older than your computer you may need to check for driver updates or patches. Visit the manufacturer's Web site and look on the tech support page for any relevant downloads.

7. Clear paper jams. It should be obvious if you have a paper jam (your printer won't print). Always refer to the manual for the safest method of clearing jams. In general, be gentle and access the areas easily reachable by lifting a cover or removing a panel.

How Does An Interphone Work

An interphone system is an communication system linking rooms in a building, ship or aircraft. It is similar to an intercom system.

Uses

Interphone systems are used mainly in hotels, apartment buildings, ships and aircraft. They enable communication in several ways. Many interphone systems are push-to-talk (PTT) systems, much like walkie-talkies. Others, like many in apartment buildings, involve telephones.

Features

Most interphone systems also enable communication with outside locations. In many apartment buildings visitors push a button to communicate with a resident. The resident's phone rings and a conversation takes place. These devices also allow residents to place calls to outside locations. The same interphone system that enables a pilot to communicate with flight attendants on a commercial aircraft may also be used to communicate with radio towers.

Details

PTT systems are two-way audio connections using a central amplifier. In many systems, information is transferred through wires interconnecting the units. With current technology, some systems are now wireless. The wireless systems operate like standard walkie-talkies.

Root The Mytouch 3g

Rooting your myTouch 3G Android smartphone opens up a host of features usually unavailable to the phone with the stock software that comes preloaded from the factory. Rooting allows for better performance, more options and features, and the ability to install apps from your microSD card. Making this change to your phone, however, is not authorized by the handset developer, and you should do it at your own risk, as it may damage the phone. The features are not directly supported either, so troubleshooting any problems would have to be done through resources available online.

Instructions

1. Access your phone's settings and under the software sub-heading, enable your phone to allow untrusted sources.

2. Navigate to the Recovery Flasher URL (see Resources) from your phone's browser.

3. Run the "Recovery Flasher" app that you just downloaded and installed.

4. Touch "Backup Recovery Image" and then touch "Flash Cyanogen Recovery 1.x.'

5. Turn your phone off and reboot it into "Recovery Mode" by holding both the "Home" and "Power" buttons to test that you successfully rooted your phone. If you did it correctly, you will see a screen that lists "CyanogenMod" along with the build number at the bottom of your screen.

Hp M425 Digital Camera Troubleshooting

Bad software and equipment will also cause the HP camera not to work properly.

The HP Photosmart M425 is a point-and-shoot camera released in 2006. It is a compact camera that shoots at 5 mp and has a 3X optical zoom lens. Included with the camera is software that allows quick button printing of photos and sharing of photos from the camera. The camera has a 1.7 inch display for image viewing. This camera is robust, but problems may arise with the software or hardware over time.

Instructions

1. Inspect the USB cable if the camera is not recognized on your computer. Look for exposed wire or any broken elements. Change the cable for a USB that is known to work. Try different ports on the computer and try other devices in the computer ports to ensure they are working. Plug the camera into a high-speed USB hub if your computer has one.

2. Check that your computer software that connects to the camera when it plugs in is up to date by running the software update in the help section of the HP software.

3. Check the firmware on your HP M425 by holding down the flash button while you turn on the camera. The firmware should be 1.44 or 2.23. Check the firmware if you are having problems focusing in Sunset mode, if you are receiving error messages, have short battery life, have problems with retracting the lens or have issues with large file transfers.

4. Check that the SD card inside the camera is good by switching it out for a new one. A faulty SD card will cause error messages when taking pictures or attempting to transfer files.

Use The Bluetooth On A Nokia 2760

Bluetooth technology is a way to boost your mobility when talking on the go. It similarly provides a wireless network for transferring files and pictures that you have acquired on a mobile device. Enabling and using this function can be beneficial whether for business or for pleasure.

Instructions

1. Select from the menu "Settings" --> "Connectivity" --> "Bluetooth." This will bring you into the Bluetooth menu function, allowing you to configure your Bluetooth technology. In this menu, you'll find an option to turn Bluetooth on or off. Select "on."

2. Look for devices on the mobile phone that will be compatible with a Bluetooth device. There is a menu option to seek these devices. If a device is listed on the menu, you have the option to pair this device with your mobile phone. To do this you'll need to enter your security password. This is generally created when initially setting up your mobile device.

3. Check for the visibility option. The phone does have an option to either make your bluetooth device visible or invisible to other Bluetooth and mobile devices. It's your decision to remain private or broadcast your signal.

4. Use Bluetooth for data transfer. Once connected, you'll be able to transfer calls to your headset, transfer photos from your cell phone to your computer, transfer photos from your computer to your phone, and transfer files back and forth. Ensure your invisibility when transferring sensitive information to avoid hackers and losing information to other Bluetooth users.

Take 120 Film Pictures

You can capture much bigger images with 120 film than with 35mm film or 35mm-style digital cameras. The standard negative size for 120 film---depending on the camera---is 2.25-by-2.25 inches. The 35mm negative, because of the perforations to transport the film, only has an image size of about 1.5-by-0.75 inches. The beauty of 120 film is that it can be used in the highest-end medium-format camera ever made---the Hasselblad---and the lowest-end "toy" camera, the Holga.

Instructions

1. Buy a variety of different 120 film rolls. The film is available as color slide, color print and black and white print film. It also is available as black and white film that is developed in color chemicals, namely Kodak's CN and Ilford's XP-2. This may make it easier to get it developed at a nearby color lab, but check to make sure the lab can handle the bigger film size.

2. Load as many film backs as possible ahead of a photo shoot. Medium-format cameras have detachable film backs, most of which have a dark slide to protect the film from exposure when the back is not attached to the camera. Since loading 120 film is the longest part of the process, using multiple backs will speed your shooting. These backs also make it possible to change film types mid-roll. The exception is the Pentax 645. Its film back plugs into the camera with no protection from light mid-roll.

3. Remember that the film frame is much bigger. Move in to take photos of people. Conversely, you can take shots of landscapes and expect to get a lot of detail, even when you blow up the image. For most 35-mm shots, the top range of an enlargement is about 8.5-by-11 inches. You can go bigger with a 2.25-square-inch negative.

4. Take shots of things you normally wouldn't think of, such as close-ups of flowers or birds (you may need a telephoto lens for that) to really get the full effect of 120 film. If you are shooting with a high-end medium-format camera such as a Hasselblad, Bronica, Mamiya or Pentax, take full advantage of the lens. Some of these lenses, particularly for the Hasselblad, are the best optics available, so use them for subjects where clear, crisp detail is necessary.

5. Develop your own film. Famed photographer Ansel Adams used to say half his work was behind the camera and the other half in the darkroom. You can develop your own black and white 120 film without a darkroom---you just need a 120 film reel, 120 film tank and chemicals---and then scan the negatives or slides into your computer. You can use photo editing software such as Adobe Photoshop do to the work Adams did with an enlarger.

Make An Sband Bandpass Filter

Filter capacitors reject unwanted frequencies.

Frequency filters are electronic circuits that determine which frequencies pass through the amplification stage of an audio device. A bandpass filter is a static frequency filter. While a dynamic filter such as an equalizer permits you to adjust the frequency filtering parameters, a bandpass is set to a fixed range. S-band refers to the range between 2 GHz and 4 GHz. You can modify your existing audio equipment to receive only frequencies in the S-band range, by building an S-band bandpass filter circuit.

Instructions

1. Mount the blank circuit board in a bench-clamp, or bridge it across two books to elevate it at least 2 inches off the work surface. This prevents the capacitor and inductor connector pins from getting squashed when you populate the board.

2. Color-code the schematic -- the document that illustrates the layout of, and relationship between, the capacitors and inductors. This way, you can quickly cross-reference your work when populating the circuit. Mark each component in its own color, using colored-marker pens, then use the same color to mark the relevant turret on the circuit board and the symbol on the schematic.

3. Mount the filter capacitors, inductors and coupling capacitors onto the blank circuit board. Refer to the color-coded schematic to determine the correct turret for each component. These are the integral components for an S-band bandpass filter. The filter capacitors in an S-band bandpass filter reject frequencies outside the 2 GHz to 4 GHz range. The inductors store an electrical charge, which drives the signal received by the filter circuit to the amplification circuit.

4. Push each board-mounted component into its turret, with sufficient force to drive the connector pins through to the base.

5. Remove the board from the clamp, flip it over and reattach it so the connector pins are facing up.

6. Push down gently on each connector pin, so it lies flat against the copper stripe on the base of the board. This stripe is the board's conductive pathway. The signal passes along this pathway, between the filtering components. Circuit boards with stripes eliminate the need for wired connections.

7. Put a small amount of rosin-core solder onto the the tip of a hot soldering iron.

8. Press the iron against the connector pins and copper stripe simultaneously, to fuse the component to the board.

9. Remove the board from the clamp, and place it on a flat surface.

10. Cut two pieces of 1-inch power wire. Strip approximately one-eighth inch from the tip of each wire.

11. Solder a wire to the input terminal of each RCA jack. Solder the loose end of one wire to the leftmost board eyelet. Solder the other to the rightmost board eyelet. The jacks enable you to connect the filter circuit to external devices, such as radio receivers and amplifiers.

12. Screw the RCA jacks onto the side of the blank circuit board, in the predrilled mounting holes.

How Do Digital Phones Operate

Digital Phones Use Microphones

Just like their analog cousins, digital phones must convert sound into electrical signals before they can perform their telecommunication purpose. This conversion is accomplished by use of a microphone, a thin membrane that picks up vibrations in the air (caused by voices or other sound) and converts those vibrations to electrical signals. These signals are then fed to the phone's processor for digital conversion.

Digital Phones Use Data Packets

While an analog telephone simply accepts the electrical signals from the microphone and sends them out to the telephone network, a digital phone first converts the electrical signals to data packets using a microprocessor. The data packet format is proprietary to the telephone manufacturer, but most vendors convert data into 8-bit packets of ones and zeros (binary packets) suitable for transmission over the Internet. Because these packets are compliant with standards for Internet Protocol, they are known as IP packets.

Digital Phones Work With A Server

Because traditional telephones work directly with electrical signals and digital phones work with data packets, a computer known as a "gateway" serves as an interface between the digital phone and the analogue telephone network. The gateway converts digital packets to analog electrical signals for outgoing communication, and converts incoming electrical impulses into digital data packets. In call center environments or other uses where a large number of digital phones are located in close proximity, the gateway server may be located in the center itself. In residential Voice Over Internet Protocol (VOIP) uses, digital phones may connect to a server in another city, state, or even country.

Digital Phones Also Decode Incoming Signals

Just as digital phones encode sounds into data packets and send them out to a server, they also use their microprocessors to decode (or, as technophiles refer to the process, demodulate) incoming data packets back into electrical signals. These signals are sent to a small speaker in the phone's handset or speaker-phone component where the speaker causes vibrations in the air that are received by the ear as sound.

Use A Circular Polarizing Filter In Photography

Circular polarizing filters are one of two kinds of polarizing filters. They stream the amount of light coming into your camera lens and allow you to reduce the amount of glare on an object. If you're photographing water, windows or any other kind of reflective surfaces, polarizing filters help you create a clear image.

Instructions

1. Screw your circular polarizing filter onto your camera. Make sure to only use the polarizing filter on your lens. Other filters will block the image.

2. Check for a new exposure. Depending on the toning of the filter, your exposure will change to a lower shutter speed or higher aperture. Make sure to adjust it for a well-exposed shot. For this reason, try to use your camera to meter, rather than a light meter. Some photographers suggest adjusting your aperture by 1.5 stops to compensate for the filter, but test your own lens to be sure.

3. Point your camera away from the glare or light source. Approach the glare at an angle. If shooting in sunlight, point your camera exactly 90 degrees from the sun. This makes sure that your camera still catches the light's reflection but does not hit it directly.

4. Check your results. If you're unsure what the polarizing effect will look like, unscrew the polarizing filter from the camera and look through it. This will give you a sense of what your filter will block out.

Make An Electric Igniter From A Disposable Camera

The circuitry in a disposable camera can play a role in DIY electronic projects.

Disposable cameras with a flash have the equivalent of an electric ignition system in their circuitry. This circuitry can help create an electric igniter for use in devices such as potato or stun guns. The cost of disposable cameras is minimal, and the charge that creates the spark required stays effective long after you take the last picture.

Instructions

1. Take the camera apart. If the model of camera you purchased is held together with screws, remove them with a small screwdriver and separate the two cover sections of the camera. If the camera contains no screws, you must pry the sections apart gently using a screwdriver. You can break the shutter mechanism that operates the flash if you use too much force in this step.

2. Remove the battery, and locate the camera's capacitor, which will resemble a small blue "C" battery with wires soldered to it. Insert a small screwdriver into the area at the bottom of the capacitor between the two soldered wires, allowing the screwdriver to contact both soldered wires. This step will emit a sizable spark but will eliminate the charge.

3. Locate the flash bulb, and gently remove it. You can unsolder the two wires leading from the capacitor into the flash tube or cut them. Solder or use tape to connect two moderate-gauge 6-inch wires to the wires that connected to the flash tube. The other wire connected to the flash bulb is the trigger transformer output wire and will be wrapped around the flash bulb or tube. Solder or tape a longer wire to the trigger transformer output, which will lead to the electrode system and initiate the spark.

4. Cut the perforated board to fit inside the circuit box in which you plan to build the igniter. Select a row of holes on the perforated board on one side of the box container. Attach an electrode to the end of the trigger wire and one to each of the capacitor wires. Insert the electrode on the trigger wire into the center hole of the row you chose. Insert the electrodes on the wires coming from the capacitor on either side of the trigger electrodes. Angle the capacitor electrodes slightly so they almost touch the trigger electrodes.

5. Solder the capacitor to the bottom side of the perforated board so the electrodes attached to it don't shift and touch the trigger electrode.

6. Solder a wire lead to each of the three electrodes, and connect them to the flash circuit (the board located under the bulb you removed when you cut off the bulb wires).

7. Connect the battery compartment to the flash circuit with soldered or taped wires. Insert a battery into the compartment, and wait for the circuit to charge. You should begin to see sparks arcing between the electrodes on the top of the perforated board. Insert the entire assembly into the circuit box.

Connect An Analog Camera To A Pc

Use composite cables for the analog camera connection.

Older analog video cameras typically used either VHS cassettes or 8mm cassettes for recording. These cameras are becoming obsolete as digital cameras and minidisc or DVD cameras take their place due to advances in picture quality and the ease of editing digital video. But you can still connect an analog camera to a PC to convert the video footage into a digital format for storage. The simplest solution is to hook up the camera to an analog-to-digital converter box, which then attaches to the computer.

Instructions

1. Shut off both the camera and computer.

2. Use your thumbnail to lift the flap that covers the AV ports on the camera, then connect the yellow, white and red plugs on one end of the cable to the three colored jacks on the camera. If the camera has only yellow and white jacks, it records in mono audio only. Leave the red plug dangling in this case.

3. Insert the three plugs on the other end of the cable to the matching jacks on the analog-to-digital converter box.

4. Connect the USB cable from the output port on the converter box to any USB port on the computer.

The Differences Between Nikon 300mm Lenses

As of May 2011, Nikon manufactures two 300mm lenses: the AF-S Nikkor 300mm f/4.0D and the AF-S Nikkor 300mm f/2.8G VR II. Because both of these telephoto lenses feature an internal focusing system, they do not require the use of a camera body compatible with AF-D lenses. The AF-S Nikkor 300mm f/2.8G VR II is the newest of the Nikon professional telephoto lenses and incorporates Nikon's latest technology. The AF-S Nikkor 300mm f/4 has an older design.

Aperture

The aperture indicates the amount of light that the lens is capable of capturing. A lens with f/2.8 captures twice the amount of light that a f/4 can capture. The photographer is therefore able to use a higher shutter speed or a lower ISO with the f/2.8 lens, compared to the f/4 lens. A lens with f/2.8 also creates images with a shallower depth of field. The minimum aperture of the Nikkor 300mm f/4.0 is f/32, which is greater than the f/22 minimum aperture of the Nikkor 300mm F/2.8. The smaller the aperture the bigger the depth of field but the more light is needed to take a photograph. Like all lenses, both the Nikon 300mm will start losing image quality when using an aperture smaller than f/8 or f/11.

VR

The AF-S Nikkor 300mm f/2.8G VR II features a VR, or vibration reduction, system designed to reduce the vibration of the lens when hand-holding the lens. As a rule of thumb, a photographer can hand-hold a 300mm lens and get sharp images only if using a shutter speed of 1/300th of a second or faster. With VR, that time is reduced to 1/40th of a second. The AF-S Nikkor 300 f/4.0D does not have VR technology, requiring the use of a tripod or other stabilization method in many shooting situations in which a photographer could hand-hold a AF-S Nikkor 300mm f/2.8 G VR II lens.

Size and Weight

The apertures f/2.8 and f/4 indicate the ratio of the size of the focal length and the size of the front element of the lens. Because these two lenses have the same focal length, the f/2.8 lens will be physically larger than the f/4 lens. The VR system and its better weather sealing add bulk to the AF-S Nikkor 300 f/2.8G II. The AF-S Nikkor 300 f/2.8G II measures 4.9 by 10.5 inches and weighs 6.39 lb., and the AF-S Nikkor 300 f/4.0D measures 3.5 by 8.8 inches and weighs 3.17 lb.

Price

Released in 2010, the AF-S Nikkor 300 f/2.8G II 2010 features the latest and best of what Nikon has to offer. The AF-S Nikkor 300 f/4.0D was released in 2003 without VR and with lower-quality construction and with fewer control options, for example, a button to lock the focus to a specific point or lock the focus to a specific range. It also uses lower-quality glass. The AF-S Nikkor 300 f/4.0D costs around $1,300, and the AF-S Nikkor 300 f/2.8G II costs about $5,600, as of May 2011.

What Is The Best Pixel Number For A Digital Camera

When buying a digital camera, every consumer is faced with the same question. What is the best number of pixels? Depending on your use for the camera, and your budget, the number of pixels can be a very important consideration. Don't overspend for more pixels than you need, or cut yourself short with your digital work. Pixels are the paint on the digital photography canvas. Take a moment to learn more about what pixels are, how they effect your digital images and what number you should choose for your photography needs.

Features

Pixels are the meat and potatoes of a digital image. Pixels, or picture elements, translate into tiny little dots of information in a digital picture. If you could zoom in on a picture close enough to see the pores of human skin, you would be looking at each individual pixel that makes up the photograph. Pixels are organized pieces of digital data, positioned together to make up an image.

Identification

Digital cameras are rated by the number of pixels they use to capture images. The term "megapixel" refers to the millions of pixels available on that camera's sensor. An 8MP camera contains 8 million pixels on its sensor, which means it gathers 8 million pieces of information to make one whole picture. (MP is the abbreviation for megapixel.)

Types

There are a few different types of digital sensors. A compact digital camera has a CCD sensor covered in light receptors, or pixel wells. An SLR (single lens reflex) camera most often contains a CMOS sensor. The pixel wells on a CMOS sensor are larger, and produce more detailed data.

Benefits

Selecting a camera with a larger megapixel rating means your images will be recorded with more information. Think of an artists's canvas. More pixels are equivalent to more strokes of paint to create a picture. If you have more paint, or pixels, to work with, your pictures will be clearer, contain more fine details and be sharper. When more data is recorded, it is easier to enlarge the photo and have the image still look sharp and clear. Cropping a picture that originally contains a lot of pixels will also produce a clearer image than one made from fewer pixels.

Misconceptions

Using a camera with a large number of pixels, or high megapixel rating, doesn't mean you will instantly have better pictures. Taking a good photo also requires getting the camera focused, attaining the proper exposure and framing the photo well.

Most digital camera users can't tell the different between a photo taken on a 5MP camera or a 10PM camera, until the image has been altered. Those extra pixels become noticeable when the photo is enlarged and stretched or cropped to enlarge a specific portion of the picture.

Digital camera users that use their photos on the computer exclusively, rarely notice a difference in image quality between a 5MP and 10MP camera, since they are only viewing them on a computer monitor.
