Hi @Alfiezoom 

Thanks for posting in our business forum.

Is there a router on the network? If not, the NVR will play as the DHCP server. So, make sure your HV cameras are under the subnet of the DHCP server hosted by the NVR. 

Make sure they are under the same network(subnet). It should add them normally.

I discovered that the nvr wasn't connected properly to my router. 
 

I fixed this, but there is now a different error. I believe this is because the cameras have an IP of 192.168.254.X instead of 192.168.1.X. Is this right?

 

I tried to change the camera IP through the nvr but it's now asking for a password... if I skip that window it fails. 
 

Assuming this is why it's failing, do you know if there is any way to change my network IP to 192.168.254.X instead of having to figure out how to reset my cameras?

You cannot skip the password if you have one.

AFAIK, all cameras have authentication systems. I don't think you should skip that.

Change your router subnet to 192.168.254.0/24. Or set a static IP address to each one of the IP cameras and NVR. This will be done manually. NVR cannot batch change that because it does not have control on your IPC.
