NVR and Cameras on different IP?

Hi all, I have a bit of a situation and I'm not really an expert on figuring this out. The solution I have in place was originally provided by someone who worked in residential/commercial security solutions but I no longer have any connection to them.

My current NVR is 4 cams max and I purchased another NVR to scale, but the first issue I've noticed is that my original NVR is sitting within one subnet and the cameras are sitting within a different subnet.

The NVR is a Model#4108H-P-2T, sitting on 192.168.x.x whereas the cameras are sitting within a 10.1.x.x range.

Simple plug 'n play to the new NVR has not been successful and I think the IP conflict might be just an additional hurdle so asking about that first. Any insight here would be great, thank you!
 
Nvr poe ports normally 10.1.1.xx starting with 65. So new NVR you trying access on same brand NVR or did you mix, then is NVR POE?

If not POE then will need ip camera tools to change to your ip that you want to use for NVR.

From what I can tell, my OG NVR is Dahua and the one I purchased to scale is a Hikvision DS-7608NI-E2/8P. The cameras are all POE.

I assume then I want to force change the cameras over to the 192.168. range I want? Any way to make them grab one through DHCP?

Yes you could setup the cameras to DHCP and then connect to the NVRs POE port, Keep in mind that some POE NVRs from Hikvision are really brand loyal. Some can force the cameras others won't work at all. Some might need to make sure that ONVIF is turned on and able to work on the POE portion of the NVR..

Will need to work Dahua cameras in ONVIF for it to work. So if the cameras have Onvif disabled that will also need to be turned on..

However I would personally setup the cameras Static IP to match the PORT you want to connect it too.. Then make the connection and change and update to work with ONVIF again is it is supported... This way there will be not issues with IP after reboots and or power changes.. Once connected the camera and NVR could follow, What I mean is setup for on POE if connected to Lan again NVR would notice and change to new lan IP.. Or at least that is what has happened with my system when i move for testing or making changes and give it a lan IP the NVR auto found it and change IP I was like ops lol..

What brand are the cameras?
It's always best to keep NVR's and cameras from the same manufacturer for full functionally

Ok I understand most of this in theory, however how do I know which ports I want the cameras to be sitting on?
 
Some NVRs are POE only others will work with Both POE and normal Lan So if you had NVRs like mine then you could scale out your system using POE+ Switch or POE switch if you were never going to use a high power POE camera.. Personally I would use POE+ switches..
