Dahua Auto focus lock off focus

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

Thanks for the link. I'm pretty much an idiot when it comes to this type of stuff. Is there a discussion that goes into more detail about setup of the system? I honestly don't know how this works. I understand the cameras have to be connected to a network switch, and then a pc on the network is required, but what software/program is used? Does the Sunrise Sunset software handle everything? Does the video feed from the cameras store on the computer hdd? See, told you I'm an idiot with this stuff lol... That's why I haven't done this. I'd love to, but I'm not sure anyone would be willing to take the time to help me understand what I need to do. I think it's just assumed that you already have the required knowledge to apply the utility.

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.

I had to do the same thing. IIRC, I set my Day profile to start at 8am and end at 5pm est. Where I live, the latest it gets light enough to see well in the morning is 8am, and the earliest it gets dark is 6pm. DST really messes things up. I wish they would just do away with it, but that's another topic altogether. I've noticed that my camera still has focus failures occasionally after switching to night profile due to very overcast days causing not enough light for it to focus properly. Moving it back an hour before certainly helped, but it's still not a set and forget thing. Still have to keep an eye on it.

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..
A possible fix for nighttime IPC-HFW5231E-Z12 autofocus issues

Computers have the same ip range as the nvr(192.186.....) but not the cameras, which the nvr assigned 10.x.x ips

Will it work??

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!
