Difference Between DVR vs NVR . Which Is Better

The difference between the network video recorder (NVR) and digital video recorder (DVR) is in how they process raw video data. 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. Unless they’ve been reconfigured, the DVR connects to an analog CCTV system via a coax , while the NVR connects to an IP camera system over an Ethernet or WiFi connection.
