What Is an NVR, Network Video Recorder, Definition and How It Works
An NVR, or network video recorder, is a device that connects to IP cameras over an Ethernet network, receives digitally encoded video from each camera, and stores that footage on a local hard drive without requiring a cloud subscription or monthly fees. Camius NVR systems are available in 8-channel, 16-channel, and 32-channel configurations with bandwidth from 128Mbps to 640Mbps and storage from 4TB up to 80TB. Unlike a DVR, which encodes video at the recorder from analog cameras, an NVR receives video that each IP camera has already encoded, which supports higher resolution and more flexible installation.
