what is the difference between nvr and dvr security systems?

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.

The difference between DVR and NVR security systems come down to the cost, how the data is transmitted, and type of cameras involved. 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.
