What is the best webcam?
A webcam is a special compact camera,designed to work on the Internet. If the laptop or computer monitor does not have a built-in web camera or is not satisfied with the image quality obtained from such a camera, you can choose from a large number of these devices offered on the market.
When choosing a webcam, you should know that there is noa specific classification of cameras and there are no clear requirements for image quality. Therefore, before buying, be sure to view the image created by the device. Also, for reliable operation of Full HD cameras, a reliable high-speed Internet connection is required.
Type of matrix
In webcams, there are two kinds of matrices - CCD andCMOS. The difference between them is in the ways of image processing. Matrices like CCD give a better picture, but are much more expensive. Therefore, in most webcams, CMOS-type matrices are installed. If such a device is intended to be used with a face recognition program, it is better to select a CCD matrix. Matrix Resolution
The standard resolution for web cameras is 640x480pixels, this is 0.3 MPix. If the webcam is also supposed to be used for shooting home video, then it is better to choose a resolution of not less than 1.3 MPix - 1280 x 720 pixels. Such HD cameras already have a good price-quality ratio. The maximum resolution for web cameras is 5 MPx - 2592 x 1944 pixels, but such cameras require a high-quality high-speed Internet connection, otherwise the image will simply not be transmitted. Manufacturers often cunning with this parameter and on the box with a camera of 640 x 480 pixels you can see a proud inscription - 16 MPix, but somewhere on the side of the small font will necessarily indicate the real resolution of the device.Frame frequency
This parameter determines which imagewill see the interlocutor - a normal video or, roughly speaking, a kind of slideshow. The minimum required frequency is 24 frames per second, the optimal one is 30. Some cameras operate at a frequency of up to 90 frames, but this greatly increases the amount of information transmitted.Extra options
The sensitivity of the camera is the ability to shootat a low level of illumination. Important if you are going to shoot in the dark. Autofocus - this function is useful when shooting in motion or moving objects. Very useful is also the presence of a built-in microphone. Another thing to pay attention to is how to attach the webcam and connect to the computer. The USB 2.0 port is mainly used, but USB 3.0 can be used. So you need to make sure that you have the correct connection ports on your computer beforehand.Webcam Defender G-lens 2693 Full HD
