I read the entire post but not find solution
. I can't find the difference of the POE via injector or via NVR
I more or less understand how it works. i acces via web interface NVR
For the cameras I have put the range 192.168.1.X
For the NVR 10.30.6.45 because the main network of my work is 10.30.6. *
I can access the camera and its configuration with a POE injector directly. The address is 192.168.1.91
When I connect it to the NVR and access the interface it can't find it.
but curiously, on the first try, he found two cameras of different brands and of worse quality than the Alhua dome.
