I've got 4x Dahua cameras and added a 5th tonight, loaded up the Configtool, initialized the new camera, but I've been unable to change the IP address. For reference in the picture, MAC ending f9 is the new camera that I want to change the IP to 192.168.1.120 and MAC ending e0 is an established camera which should be at 192.168.1.108. When I try to "Batch Modify IP," I input the IP info as shown in the attached picture, but it gives me an error that says "Operation Result Network error, maybe timeout." Unsure what I need to do next? I cannot seem to uninitialize? Reset the camera?

Or if your wifi router supports it, maybe use dhcp reservation to assign that mac to desired ip.

MAC Address ending E0 and F9 are the same IP address, this is the problem. Unplug one of the two cameras, change the IP to something other than .108 using the DahuaWIKI @EMPIRETECANDY provided. Re-connect the other camera, and change its IP address as well.
Good stuff from @Mike A. and @SpacemanSpiff , IMO, which begs me to recommend not leaving any in-service Dahua cams at the default .108 IP or Hikvisions at .64, as it can create unnecessary aggravation such as the above when adding a new cam.

Never establish a camera at .108. That needs to be reserved for new camera config.
