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.
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.
Cable in box
Detachable cable design provides additional options for connecting a WEB-camera: the bundled cord can be changed to a longer or shorter one. Also
, the detachable cable is very convenient for storage and transportation.
The built-in cable is always in place - you can lose it only with the WEB-camera itself. On the other hand, a fixed wire cannot be quickly replaced with another one (for example, a longer one); and if it is damaged, you will have to carry the WEB-camera for repair or change it entirely.
