At the same time, due to the need for a control center through the console to control the camera, lens, PTZ, etc., and thus in the transmission system also contains the transmission of control signals.
8, control and recording part
The control and recording part is responsible for the control of the camera and its auxiliary components (such as lens, PTZ), image, and sound signal recording. The current hard disk recorder technology has developed more perfectly, it can not only record images and sound but also contains a screen splitting switching, PTZ lens control, and other functions, basically replacing the previous use of screen switchers, screen splitter, PTZ controller, lens controller, and other products.
9、Display part
