What Are the Differences Between DVR vs NVR?

While searching for a CCTV camera, you might find terms for camera systems like Network Video Recorder (NVR) and Digital Video Recorder (DVR), but what do they mean and what should you pick between DVR vs NVR? Find out below.


About NVR

A Network Video Recorder or NVR records and retains video from the network which is done through your wireless network with an IP camera. This allows it to record at a very high resolution, all the way up to 4k resolution in exchange for a less stable signal.

About DVR

A Digital Video Recorder or DVR converts the raw footage sent from the analog CCTV camera into a digital video file through a coaxial cable. The file is stored in a hard disk. This results in a lower resolution video but with a reliable connection.


Both DVR and NVR record and stream videos reliably, with NVR offering a higher quality of the video. So the main difference between the two systems is the scalability, the method of transmission of data and the type of cameras used. While NVR has an easier installation method, higher video quality and native audio support for cameras with mics, it tends to be more expensive than a DVR system. However, if you just need a straightforward security setup, a DVR will be satisfactory especially if you already have a preexisting coaxial cable setup from a previous security system.
