A Network Video Recorder, or NVR is an internet protocol (IP) based device that sits on your computer network. Since the NVR sits on your computer network, Network Video Recorders can be accessed and managed remotely via your Local Area Network (LAN) or over the Internet, allowing you greater flexibility. One of the basic functions of a NVR is the simultaneous recording and remote access of live video streams from your IP cameras. One of the main attractions to Network Video Recorders is their ease of use and installation.
Typically, a Network Video Recorder will feature advanced recording and playback capability, an intuitive remote control unit, a user-friendly graphical user interface (GUI), Intelligent Motion Detection, and PTZ camera control. NVRs are designed to handle the vast amounts of simultaneous video streams coming in for recording and broadcasting the same feed out live to client machines locally or remotely.
