Question: I have IP cameras on the PoE switch in the network. The search is greyed out. How do I add them to the Camius PoE NVR?

Answer:

To add cameras not connected directly to the NVR, move the mouse cursor to the bottom left, click the main menu button, and then click Setup >> Channel. 

On the Channel list on the bottom half, right-click on a free channel with POE in red and switch from ‘Auto‘ to ‘Manual.’

After this step, this search button will not be greyed out anymore.
