When choosing a web camera, you should know that there is no specific classification cameras and there are no clear requirements to the quality of the image. Therefore, it is necessary before you buy be sure to view the created device image. Also, for correct operation of Full HD cameras require high-speed, reliable Internet connection.

The type of matrix

Web cameras are two types of matrixes – a CCD and CMOS. The difference between them consists in the methods of image processing. Matrix type CCD give the best image, but are much more expensive. Therefore, in most web cameras are installed matrix type CMOS. If such a device is supposed to use facial recognition, it is better to choose a CCD matrix.

The resolution matrix

Standard resolution for the web camera - 640 x 480 pixels is 0.3 megapixels. If the webcam was supposed to be used for shooting home video, it is best to choose a resolution not less than 1.3 megapixels – 1280 x 720 pixels. These HD cameras have a good ratio quality-price. The maximum resolution for the web camera – 5 Mph – 2592 x 1944 pixels, but these cameras require a high speed Internet connection, otherwise the image will not be transmitted. Manufacturers often disingenuous with this option and the box with the camera is 640 x 480 pixels, you can see the proud inscription – 16 megapixels, but somewhere on the side in small print is sure to be a valid resolution of the device.

Frame rate

This parameter determines which image will see the source is a normal video, or, roughly speaking, a kind of slide show. The minimum required frequency of 24 frames per second, the optimum – 30. Some cameras operate at a frequency of 90 frames, but this greatly increases the amount of information transmitted.

Additional options

The sensitivity of the camera is the ability to shoot in low lighting. Important if you plan to shoot in the dark. Autofocus – this feature is useful when shooting in motion or moving objects. Very useful is also a built-in microphone.

Another is to pay attention to the method of fixing the webcam and connect to the computer. Mostly used USB 2.0, but can be applied and USB 3.0. So in advance to make sure your computer has the necessary ports for the connection.
