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

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".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.
No IT admin. So if I change the subnet mask to 255.255.255.0 and the gateway to 192.168.0.1 but leave the IP address at 239.255.42.42 then it should work?of course if your Apartment has an IT admin.....then they may have other network addresses in play........
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.I just did a device search and it came up with one camera, I'm assuming that's the down camera.

I'm sure that's possible but I'm leaning towards it being a bad channel on the switch or a bad camera. That's more of a guess than anything, lol. When I tried to do another "Device Search" it came up with no results, no matter how many times I hit the button or how long I waited it came up with nothing but the other 3 cameras on the switch still work fine. The cable and connectors are also fine so I guess my next attempt will be to switch around a couple cameras on the switch and see if they come up or if they have IP conflicts? Or if I do have a bad channel on the switch I'm wondering if it could fry a camera?I wonder if the surge somehow messed up the NVR to think it has less channels that it does?

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?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.
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.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..

Cameras 1 - 9 and 14 - 16 are plugged into the NVR, cameras 10 - 13 are plugged into the switch then the switch is plugged into the router so there's actually 4 free channels on the back of the NVR but the camera that is down is camera 12 that's plugged into the switch. Now can I delete channel 12 on the NVR and expect the NVR to fill that spot with the down camera?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.
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?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.
You should be manually assigning static IP addresses to the cameras on the external switch by logging into the camera GUI and assigning them.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.
