The Best Web Camera Information

There are many different makes and designs of webcams, and a few features each camera can carry out. Of course every camera has a lens, and it can record video, but that does not mean it has a microphone, for example. For some, normally cheap webcams, you need to buy a seperate microphone, or simply if the quality of the webcam built-in microphone is not good (if it has one) then you may also consider an external mic.

Some cameras have the ability to zoom. Although they can zoom, sometimes the picture can become pixilated, meaning that the tiny squares that make up a picture get bigger, reducing the quality. For example, the higher the number of megapizels, the better the quality of the camera, however it can also depend on other things, like the lighting conditions and so on.

So in that respect, a camera with 1.3MP is going to be less quality than a camera with 5MP. A number of more expensive webcams come with software in which you can do cool things, and add features and effects to your webcam without having to download seperate software. ManyCam is a freeware example of something that you can use without paying, and it will add effects to your webcam, like it’s snowing inside your house, or you are on fire, or it could scroll text across your webcam.

Some more expensive webcams have paid software that comes free when you purchase the webcam, although not all of them have them. Tracking is also another very cool features a number of webcameras today have. Tracking in a webcam finds your face, and then follows it where ever it goes. For instance. if you move slightly to the right, the robotic lens will follow your face, but not all cameras have this.

Webcams vary in price, so really it doesn’t count on how much you should pay for the item, but how much you would be prepared to pay for it. For example, is your budget 10 dollars/pounds, or 100. Of course, you are going to get a better camera if you pay 100 dollars, rather than 10 dollars? Not exactly. Some prices can be boosted by the name. Microsoft is a large company, so more people would probably buy their items, as they see it on their operating system/computer.

Other less popular companies may have better quality for webcams, but marketers can take advantage of the fact people will by hardware with a certain large brand, so they rise the prices very high. Some people prefer Logitech, some Microsoft and others, but it all depends on the features you want. Always read the specs before purchasing a product to make sure it is compatiable with your programs, systems, and it can keep up with demand. Don’t buy the first one you see and shop around to get the best deal.

Webcam Problems - Troubleshooting

Broadband internet brings people many conveniences, one of which is shortening the distance between people who are far away from each other by using their webcams for video chatting and online meetings. But doubtlessly these camera devices also would expose many problems when using. Here I will talk about some troubleshooting tips.

Common webcam issues contain that PC camera is non-responsive; images are blur or even no images; you might actually get an error message or will not be able to choose the camera as the video source in your program, etc. However, before repairing your webcam issues, make sure you know well how to use this device. You can refer to the manual and all documentation that came with it. Then we begin to locate the problems.

Step 1 Check whether the connection between your webcam and computer is active or not (laptops with a built-in webcam can skip this step). Make sure your USB cable is properly plugged, and also try to connect your camera directly to your PC rather than a USB hub (if you are using).

Step 2 Turn off your computer, unplug the webcam, boot up your machine and then plug your camera back in. Let the system pick up the webcam, probably reinstall or repair drivers and then see if that works.

If it fails, go to the Device Manager and check, there are tow possibilities: One, it might be recognized as a camera, but the right driver is not installed or missing; a yellow exclamatory mark beside Camera under the list of Sound, video and game controllers will indicate a problem.

The second possibility is that this camera is not recognized by your system, and it will be listed under Other Devices in Windows XP with a question mark beside it. In either case you need to update the driver; since Windows fails to install a right one for your camera, you can download an automatic driver tool to help you. Personally I use Driver Checker, it scans your PC for installed hardware and allows you to install and update the right drivers quickly and easily.

Step 3 If the above tips fail, uninstall the software that came with your camera by using the Add or Remove Programs in the Control Panel, and then restart your PC as well as reinstall the webcam software. This method can fix the problems in most cases, but depending on the software sometimes you need to unplug your camera when installing the software.

Step 4 Most of the webcam programs have options of video source for the webcam feature, if you have multiple devices that qualify for video, you need to choose your camera as the source for the webcam feature in that program.

Step 5 Make sure your computer has the latest version of Microsoft Direct X, version 9 or newer, since all webcams and other video applications use Direct X for video processing.

To check your Direct X, you can click Start and select Run; type dxdiag in the open box and click OK; choose the System tab and then you can see the version of your Direct X tool at the bottom of the System information section.

Step 6 If the quality of your webcam's images are blur, check if it has a focus ring. If it has one, try to get the subjects in frame, in the position they will be when the video is being taken, and adjust the focus ring on the camera lens until the image is sharp and clear.
