What is the difference between a NVR and a DVR?
The Differences Between DVR and NVR In a DVR system, the camera stream is captured from analog cameras. Because analog cameras are unable to process video at the source, they pass the raw video feed to the recorder via coaxial cables. In an NVR system, video is captured with digital, or IP (Internet Protocol) cameras.
Which camera is better NVR or DVR?

NVR systems tend to have better picture quality, as well as easier installation, increased flexibility, and native support for audio on every camera that has a microphone.

Ideally, the NVR should be placed in a secure area with easy access to wiring access areas, such as a utility room. For businesses with an IT room or closet, this is the best place for the NVR. The NVR can tie into your existing cable and network infrastructure and can be rack mounted for a clean installation.

Not every video recorder will work with every camera. DVRs require analog cameras, while NVRs use IP cameras, but the compatibility question extends beyond that distinction. Some NVR systems, as I said, are compatible with the IP cameras only from certain manufacturers.
