A video recorder is a tape recorder for recording TV images and accompanying sound, which can store TV program video signals, and can later send them back to a TV transmitter or directly to a TV set. The video recorder is a recording and playback device in the CCTV surveillance system. It requires a very long recording time. Most of the video recorders dedicated to the surveillance system can record 24H to 960H video. In addition, the video recorder must also have a remote control function, so that the video recorder can be easily operated from a distance, or the video recorder can be automatically operated with a control signal in a closed-circuit television system.
