At my home I am using Uniview cctv system or UNV, I can confirm that two models are working perfectly which are IPC2328SBR5-DPZ and IPC324ER3-DVPF28, I assume that all models will work with homey.
I tried to connect the whole system through the nvr, the will list all cameras in my house but nothing works, those two are connected through poe switch.
