Reuse a port in Hikvision NVR for a new Hikvision camera

Hi Guys

Please help me here!

Back in my old house, I had a Hikvision NVR and 4 Hikvision Cameras. I had those 4 cameras connected to ports 1, 2, 3 and 4 over POE. Everything worked well for many years. When I moved to my new house, I disconnected all the cameras without labelling which camera was connected to which port. In the new house, when I connected back these old cameras randomly to ports 1, 2, 3 and 4, they didn't work, so I connected to ports 5, 6, 7 and 8 and it started to work again. All well. Now I bought 4 more new Hikvision cameras but I can't get these new 4 cameras to work in old ports 1, 2, 3 and 4. I haven't installed these new cameras in any locations yet, instead connected to the NVR with a 1 meter LAN cable.

OLD HOUSE
Port1: old camera1 - worked
Port2: old camera2 - worked
Port3: old camera3 - worked
Port4: old camera4 - worked
Port5: empty
Port6: empty
Port7: empty
Port8: empty

NEW HOUSE
Port1: new camera5 - not working - network not reachable
Port2: new camera6 - not working - network not reachable
Port3: new camera7 - not working - network not reachable
Port4: new camera8 - not working - network not reachable
Port5: old camera1 - working
Port6: old camera2 - working
Port7: old camera3 - working
Port8: old camera4 - working

I can login into the WEB UI of all these 4 new cameras with the same IP that is configured in the NVR. Password for NVR and Camera is different but correct passwords are in use. I think, the ports 1, 2, 3 and 4 got messed up some how. How do I reset these ports 1 to 4? I do not want to reset the whole NVR as, what if the old cameras also stops working after the reset? What process must be followed when connecting a new camera to a port that was used by another camera?

It is either 2 things - that is a budget NVR and if the new cameras are higher MP than the original, then the NVR may not be able to handle them.

But since you tried the original cameras too, more than likely it sounds like the POE went out. These are typically connected to the boards in blocks of 4, so we "commonly" see blocks of 4 POE go out and that is probably what happened.
