I'm not the best person to reply (wait for others), but I will add that if you do have them in the same network, go into your DHCP settings and assign a separate subnet just for the cameras. This will help you identify them more easily or separate by IP address if needed. Mine are PoE and the DHCP server gives them a separate IP address subnet based on the leading characters of the MAC address.
For example, if MAC address equals AB-CD-12-xx-xx-xx (where xx is a wildcard), assign IP address from 172.16.110.1 to 199. Whenever I see 110 subnet in my network monitoring tools, I know it's a camera.
I'm not saying this is the best or only method. This is one possibility and it's working good for me.
