I'm a complete noob and was trying to set up my new camera yesterday but couldn't find it in my router. I found out the reason was because their IP addresses were not similar as my router was on 10.0.0.x and the camera factory default is 192.168.1.108. You will not be able to access the camera directly if it's not recognized as attached to your router. Since your camera is on 10.40.10.x I'm assuming your new router is on something very different for its IP address like 192.168.1.x or 10.0.0.x. The only way to access your camera is through Dahua's "config tool" is what I found. Search for that and install it. It will search for all cameras on your network. You can then edit the IP address in there. It took me an hour to figure this out!
