Network Video Recorder

     A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card, or other mass storage device. An NVR contains no dedicated video capture hardware. However, the software is typically run on a dedicated device, usually with an embedded operating system.

     Network video recorders are distinct from digital video recorders, as their 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 streamed to the NVR for storage or remote viewing. NVR is used in IP video surveillance systems. Hybrid NVR/DVR security systems exist which incorporate functions of both NVR and DVR; these are considered a form of NVR. NVR home security systems are wireless, tend to be easy to set up, can be accessed through a web browser, and allow the user to be notified by email if an alarm is triggered.
