Dahua Camera Integration

Hello

Newbie here. I added my Lorex NVR through Dahua integration via HACS.
Out of 4 cameras it pulled only 3 (and some other motion etc) but all 3 feeds are of same camera.
The NVR and HA both are connected to fortigate.
NVR creates it’s own 10.x vlan for all 4 cameras.
So for eg. NVR IP is 10.10.30.2 and HA is 10.10.50.2… Cameras are 10.1.1.0/24 ( i tried changing the subnet in NVR but it says NVR and Camera cannot be same network)…

Please give me your inputs…

Each camera needs to be added separately, with an index from 0 to 3
