An NVR (Network Video Recorder) is the central unit of your IP camera system. It records, manages, and makes your cameras accessible from anywhere. Choosing the right NVR is just as important as choosing the cameras.

PoE Ports: Built-in PoE ports simplify installation. Plan for one port per camera.
解像度： Make sure the NVR supports your camera resolution (4K-capable).
Compatibility: ONVIF compliance allows using different camera brands.
