So first off, the NVR us acting exactly as designed . It puts the cameras on a 10.1.1.x subnet that can’t be reached no matter what you do* without first connecting to the NVR and then using the IE link to reach the cameras. Built in security.
*You can connect your laptop to a port on the NVR and reach the cameras via 10.1.1.x as the laptop will get assigned an address on that subnet as well.
Show me a screen cap of the registration page of the NVR. Are the cameras using port 1,2,3 etc or 37777? If they are using 37777 you will see the problem you are describing. Usually this is because they were manually added vs allowing the NVR to find the camera and connect automatically.
I’ve not run HiK cams on my Dahua NVRs so not certain how they react to the NVR ports
