Digital Video Recorders

A digital video recorder (DVR) is designed to record surveillance video specifically from analog signal CCTV cameras.  A DVR takes the analog signal and digitizes it in order to display and record it on a hard drive as well as transmit it over the network to client machines for live and recorded viewing.  A DVR has direct CCTV inputs for each camera.  DVRs come in 4, 8,16, and 32 channel systems.  Each channel can display and record one camera.
