Video recorder is a recording and playback device in the closed circuit television surveillance system. It requires a very long recording time. Most video recorders dedicated to the surveillance system can record 24H to 960H of video. In addition, the video recorder must also have remote control function, so that the video recorder can be easily operated from a distance, or in the closed circuit television system with control signals to automatically operate the video recorder.
