What is an NVR system?
A network video recorder (NVR) is a computer system that records video footage and stores it on a hard disk, a mass storage device, or cloud storage. NVRs are paired with digital internet protocol (IP) cameras to create a video surveillance system.
Whats the difference between NVR and DVR?
A DVR converts analog footage into a digital format, while an NVR typically only works with digital footage. DVR systems process data at the recorder, while NVR systems encode and process data at the camera before transmitting it to the recorder for storage and remote viewing.
What is the difference between NVR and VMS?
A VMS is a program that allows a computer to record video in much the same way as an NVR.

The difference is in the functions, longevity and ease of use that they offer the user.
