Network Video Recorder (NVR) Meaning
A Network Video Recorder (NVR) records security video surveillance footage in digital format on a hard drive. The NVR lacks video capture capabilities, so video from surveillance IP or CCTV cameras is processed and encoded on the surveillance IP or CCTV camera and transferred to the NVR via ethernet or Wi Fi. IP video surveillance systems typically use NVRs.
