Difference Between DVR and NVR

DVR stands for “Digital Video Recorder” and NVR stands for “Network Video Recorder”. The main purpose of both DVR and NVR is to record the video. The main difference between the DVR and NVR is that DVR processes the video signal date at the recorder while the NVR encodes the video signal data and process in the camera where the remote viewing and data storage functions performed by NVR recorder.

Another difference between DVR and NVR is that analog cameras are needed in DVRs with coax cables while IP cameras (Internet Protocol) are required in NVRs as they process the video data signals differently through Ethernet cables. Keep in mind that NVR can be wired or wireless system whereas DVR can be wired security system.

If image quality is the consideration factor, NVR security system is better than DVR system as NVR process the data via digital System as compared to DVR analog system. In addition, the video and image quality of NVR system is better than DVR but NVR security system is little bit expensive than DVR. In recent technologies era, both systems are reliable and the suitable option depends on the user needs.
