♦ * NVR

Network Video Recorder

IP cameras utilize a NVR to store, save, and view the video that is encoded and digitized in a IP Camera. NVRs allows advanced control of the video surveillance systems and projects the video into the security team's control center.

NVRs are to IP camera what DVRs are to analog cameras. With an analog system, cameras send video signal to the DVR which turns the analog signal into digital video files. Since, IP cameras deal directly with digital signals, they do not need to encode the video files, and instead focus on controlling them, displaying them, and often running advanced video analytic software.

Many PC Based DVRs also have the capacity to function as NVRs, but depend upon their internal components. If you have security camera system that has both IP cameras and analog cameras, your best choice is often to use a PC-Based DVR/NVR.
