in general, many NVRs PoE ports are not designed to have a switch downstream .. thus the diagram ..
That's what I was wondering. If the NVR POE ports were even designed to handle a switch?

No the POE ports of the NVR are not designed to handle a switch (although some have got it to work). The proper way is to connect the LAN/WAN port of the NVR to the switch.
of course if your Apartment has an IT admin.....then they may have other network addresses in play........
I just did a device search and it came up with one camera, I'm assuming that's the down camera. When I tried to add it to the system it said, "Please remove a device first, there is no free digital channel now!". It says that if I click the Add button or the Manual Add button. I also noticed the IP address, subnet mask and default gateway on the camera found are all the same numbers, 239.255.42.42. but on the monitor in the blank square it says, "192.168.0.236 Can not find network search".
I wonder if the surge somehow messed up the NVR to think it has less channels that it does? One usually gets that error if they try to add more cameras than the NVR is designed for.
The "please remove a device/bad channel" is an NVR issue. It would not get that error from an external switch issue.
Now what it could be is that the NVR already has all the channels allocated and you may need to delete the problem channel so that you can add the camera back.
So let's say as an example that it is a 4 channel NVR that had 4 cameras connected. Power surge wipes out settings to 4th camera but the NVR still has it registered to that channel so it comes up black. But you see cameras on channels 1,2,3. So delete camera 4 in NVR and then add it back.
That makes perfect since but out of 16 channels on the NVR I only have 12 cameras physically plugged into it, the other 4 are on the switch which includes the down camera.. It's an 8 channel switch but not sure how to delete a switch channel or if that's even possible?
So you have a 16 channel NVR with 12 of the POE ports on the NVR being used PLUS 4 that are attached to a switch. That is 16 channels being used on a 16 channel NVR.
You can do nothing about the switch - it either is providing power or it isn't. This isn't where you delete the channel.
It is the NVR that is spitting out the error. That is where you need to delete a channel. For some reason the NVR is not recognizing that 16th camera as the one connected to it.
So you had 16 cameras and 15 are working? Which ever channel isn't working in the NVR - delete that channel. Then see if you can add that 16th camera back.
But they are not free channels as the NVR can only accept 16 cameras total whether they are on a separate switch or the back of the NVR. Internally channels 10-13 are assigned to those channels.
Yes, so if it is Channel 12 that is the missing camera, unplug the camera from the router and then delete channel 12 from the NVR and then plug the camera back into the external switch and try to add it manually using whatever IP address you have assigned to it.
Excellent advice, now when I plug the switch back in will the router automatically assign all new IP addresses to the 4 cameras, (10 - 13) or will I need to assign new ones manually?
+1^^.You should be manually assigning static IP addresses to the cameras on the external switch by logging into the camera GUI and assigning them.
If the router is assigning those 4 cameras IP addresses, then that could be the problem because it probably changed the IP address based on when it sees a device on the router.
Two questions:I didn't have to manually add the IP, mask or gateway, it did it itself so I'm definitely happy now, well until another power surge, lol.
