CCTV behavior
The CCTV camera registers the data and it transmit it to the server. The server gathers data and stores or displays them openly on certain screens. Of course, the image can be accessed online, depending on needs and system. If you have one, a server can choose a stand-alone DVR (Stand Alone Digital Video Recorder).
