NVR Video Recorder

NVR (Network Video Recorder): Unlike its predecessor, the DVR, a NVR is not limited to be in the same area as your cameras cabling to one section.
 The unit can be placed virtually anywhere, it simply just needs to be on the same LAN network as the IP based cameras. In terms, a network video recorder are distinct from digital video recorders as their input is assigned on a network rather than a direct connection to a video capture card. 
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. 
An 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.

NVR is used in IP video surveillance systems. Because of the nature of these units, a camera that is capable of capturing High Resolution (Mega Pixel cameras) will record and playback as that desired resolution. Our Hybrid DVR security systems exist which incorporate functions of both NVR and DVR.
