H500 Ignores Subnet Mask
This happens when "detecting" cameras and devices on the same network, the H500 use the first 3 bytes of the IPv4 address (class C) and ignores the subnet mask. For example, on a 10.10.0.0 network with a 255.255.0.0 subnet mask (class B), devices with address 10.10.1.1 and 10.10.2.2 should be considered on the same network.
I had this problem in setup today because I use a class B 10.x.x.x network at home. Unknown devices get a 10.5.1.x address and I move them to 10.5.2.x static assignments when identified. I had moved the cameras to 10.5.2.x and plugged in the H500. It would "see" the cameras but not allow them to be added claiming they were "not on the same network". When I moved the H500 to a 10.5.2.x address and rebooted it, it then allowed the cameras to be added.
