What is a DVR?
A Digital Video Recorder (DVR) connects to an analog CCTV system via a coaxial cable. DVR would process analog footage data from the camera into a digital format and stored to a hard disk for later playback.
DVRs are often mistaken as NVRs, but they are different. A NVR input is from a network rather than a direct connection to a video capture card or tuner. Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then transferred to the NVR for storage or remote viewing. Additional processing may be done at the NVR, such as further compression or tagging with metadata.
