I have an imou Cell 2 camera that claims to be compatible with Onvif NVRs (IMOU life), but when I try to connect it to my Dahua NVR, it never finds it, and when I add it manually, it never connects.
You redacted what may have been the camera's private IP (which is unnecessary) so I cannot tell if it appears to be in the same subnet as the NVR's LAN ; if it's a POE NVR and the camera is wireless then you'll need to set the camera up with a unique static IP in the same subnet as the NVR's LAN (but outside of any in-place router's DHCP pool) and manually add the camera with that assigned IP (assigned by YOU, not by the NVR).
