How to use
Install the NVR in a rack or on a shelf and connect it to the network via Ethernet.

When Dahua AI cameras are connected, enable the desired AI functions such as face detection, perimeter protection or people counting in the camera’s settings to allow the NVR to receive and record analytic events.
Usage recommendations
For best results, use Dahua-compatible IPCs to enable full AI functionality; allocate sufficient storage based on camera resolution and retention requirements (4K recordings require substantially more capacity); and keep firmware updated to ensure SMD and other analytics perform accurately.
