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?
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!
