Megapixels

The number of megapixels in the matrix that the camera is equipped with, in other words, the native resolution of the matrix. First of all, the maximum photo size directly depends on this indicator: for example, a 1600x1200 frame requires at least 1600 * 1200 = 1,920,000 pixels ≈ 2 MP. With video, the situation is somewhat different, where the actual resolution of the matrix can be noticeably higher than required for the frame.

There is an opinion that the more megapixels, the better the image is obtained. Formally, this is not the case: the resolution of the sensor only affects the detail, and in itself numerous megapixels can even worsen the picture — especially if the matrix is small. However, in fact, high-resolution sensors are often installed in fairly advanced cameras, in which high image quality is achieved through a number of characteristics.

HD filming (720p)

Historically the first of the high definition HD (720p) standards. Initially, it assumed a resolution of 1280x720, however, in webcams, models with a different frame size are also included in this format — in particular, 960x720 and 1280x960, which have a 4:3 aspect ratio of the frame (unlike the original 1280x720, for which it is 16:9 ). Anyway, HD-models are relatively inexpensive and not particularly demanding on the quality of communication, however, they allow you to get a fairly detailed “picture”.

Field of view

The viewing angle determines, first of all, how wide the field of view of the camera is, what area of the scene being shot falls into the frame. Accordingly, a wide viewing angle allows you to capture more space and the lower the likelihood that something of what is happening will be behind the scenes. On the other hand, it should be taken into account that a strong increase in viewing angles leads to distortions of the “picture”, especially at the edges, as well as to a decrease in the size of visible objects and a decrease in detail.
