Add WD Camera over LAN

I have 4k readyview system with 4 cameras. I have already installed 3 directly to the NVR PoE ports, but the 4th I need to connect to another location on my LAN. WD Support says it won’t work but that doesn’t make sense to me. It’s being assigned a dynamic IP from my router currently but i can switch it to static. When i auto-search it sees the camera and IP, but when i try to add it i get the following error message: No more cameras allowed. Please delete idle cameras and try again.

What can i do to resolve this?

Hi J, see my reply to the other thread. It is confusing at first, but it can be done. Too bad, WD does not provide any help with this.
