Is it possible to add IP POE cams behind Dahua NVR to HA?

Hi guys, super new to this but loving HA.

I have a 16 port Dahua NVR with about 9 POE cams behind on a 10.x.x.x subnet.
I see that you can attach an IP Cam directly on the same subnet using ONVIF.
Is there any possible though to get the streams of all cams into HA?

My guess is that they would have to be exposed by linking the POE switch in the NVR to my main network then changing all their IPS to match my LAN subnet were HA sits?

Thanks in advance

I have cameras from my dahua nvr exposed in HA. I have found that the performance is pretty rubbish once I add more than 2 cameras. I’m away from home at the moment but will get code snippets for you.

I also have an appdaemon function that exposes motion events via mqtt which is pretty handy!

Did you ever get this working? I am in the same situation with an 8 port Dahua NVR.

I have not
I really wish I could integrate my cams
I have several 6 and 8meg cams that were a bit costly and i can only use them natively

Any luck for you?
