1.1 Add new add-on cameras to your system
1.2 Re-pair camera to NVR when they lose connection. You need to delete the
Network Unreachable channel at first, then re-pair the camera to an unoccupied
channel. (unoccupied channel always shows No Video Source under Status.)
Tips: The IP cameras in pre-packed kits have already been paired to the NVR. So the
cameras will automatically connect to the NVR once they are plugged in power.
2. Add camera by matching code.
2.1 Power on the camera which has no video, and connect this camera to the NVR
via Network cable.

2.3 Click "Refresh", find the camera's IP. Click "Match Code", then click "Yes", the
NVR will start to match code to the camera.
Then you will see the camera is added to the NVR and display video on the screen.
