• An NVR (Network Video Recorder) is a comprehensive IP camera recording device. It comes with a computer as well as specialised video management software. VMS is essential for video recording, but it also allows multiple viewers to watch live and recorded video simultaneously.
• A DVR (Digital Video Recorder) records video from analogue cameras to one or more hard discs. The consumer television market also uses the term DVR.
• Along with the IP cameras, the NVR is connected to the computer network. The key advantage is that you may use existing network infrastructure instead of running wire from your home base location.
• Each analogue camera is connected to the DVR via coaxial cable.
• High-resolution megapixel cameras are supported by the NVR.
• Only VGA cameras are supported by the DVR.
