Focus
Focus method — focus — provided in the design of the camera.
The simplest and most common option is manual focus; it requires some setup steps, but does not cause any particular difficulties, besides, it allows you to set the sharpness as you wish, without relying on automation.
Autofocus, in turn, saves the user from having to fiddle with the settings, however, it is also more expensive. In addition, autofocus systems may not work as you would like, and they still sometimes have to be adjusted manually (however, such a need is extremely rare).
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.
Rotation angle
The range of rotation angles in degrees supported by the webcam. In this case, it means turning the camera to the right or left, without tilting back and forth.
Indicators
Types of indicators (usually light) provided in the design of the camera. In modern models, there are (separately or together) two types of indicators:
— Nutrition. An indicator that indicates that everything is in order with the power supply. On some models, this indicator only works when the camera is turned on and ready to use, on others it can also work in standby mode — for example, it will glow in a different light than when the camera is on.
— Activities. An indicator that indicates that the camera is shooting video — and, accordingly, it is being recorded or broadcast on the Internet. Such an indicator makes it easier to keep track of the shooting mode and avoids unpleasant situations, such as accidentally broadcasting to the Internet from a camera that you forgot to turn off.
