I'm not sure what's going on, but after having to re-setup our cameras due to network changes (and forgetting the admin password) they will currently only show a live feed through the monitor if it's set to View 1 or View 4. Viewing 8 or 9 just shows a black feed with a red recording symbol in the bottom corner.
They are currently configured in the NV1108 NVR through ONVIF @ 720p 20fps and are recording normally, even when switching views to one that is black. It is only the view that's affected.
Cameras are the FI9816P if it matters.
Thank you for your help!
