Unfortunately I'm right there with you. I dont think it effects enough people to consult the school of you tube

Thank you very much. Will it work in my situation?(entire network 192.x.x, including Nvr. Nvr assigned private IPs to the cameras in the 10.x.x range)
I dont think it will if the cams need to communicate with the always on computer.
I could change the IP range the nvr uses to the 192 range, but that increases my camera exposure to the net right?

If you put your cameras on the same 192.x.x. Range as the rest of your entire network, the cameras themselves would be capable of reaching out to the Internet, but unless you setup port-forwarding on your router (or enabled the uPNP feature on the cameras), your router should prevent anyone on the Internet from being able to reach in to your cameras.
But you’re right — the computer does need to be able to connect to the camera(s) in order to flip the camera between day/night profiles (and to send it the focus commands).
If it’s just your Z12E that’s having the focus issue, maybe you can just put that one camera on the 192.x.x.x network? I don’t have any experience with a PoE NVR, so I’m not sure if it’s possible to do just one camera.
This is probably overkill, but another option (assuming your computer can be expanded, and your PoE NVR has an open port) would be to install a second network card in your PC and connect it to your PoE NVR. Then your PC should be able to access the cameras on the 10.x.x.x network, as well as everything else on the 192.x.x.x network.

Yep thats one of two parts to insure focus when it switches from Day/Night and vice versa..
The other is to provide something for it to focus on..

I am setting up a N45BA5 camera with the
DH-PFL0550-E6D 5mm-50mm Various-Focal lens for capturing tags in our neighborhood and quickly realized I needed to be able to switch profiles based on sunrise/sunset times to get things working as desired. I found this utility too and was very confused as to how I could talk directly to the cameras because of the way my DaHua NVR used a separate subnet for its POE camera ports. While talking with support I found an answer that is working great for me. My NVR is a 4port unit and I only have 3 cameras on it. The default NVR setup uses a 10.1.1.0/24 subnet for these ports and always assigns the same 4 addresses for each port. D1 is 10.1.1.65 with the next 3 being .66, .67 and .68. I have a Windows VM running the sunrise/sunset service and all I had to do was configure the Ethernet interface with a static IP of 10.1.1.68 and connect it to the D4 fourth port. (I have another interface setup with my normal network Ip/subnet/gateway so it can reach Internet and also be easily accessed via Remote Desktop. When on this VM, I can open 10.1.1.65 (or .66 or .67) and access each of my 3 cameras directly and the service does a great job of handling the focus too. If you need all of your ports for cameras it gets a bit more complicated, but can still be achieved with vlan capable switches and /or a router.
Hopefully this will work for some others needing direct camera access with the separate NVR subnet.

Well crud! Just realized this has already been covered! Sorry for the redundant post!
