Some Reolink Cameras show video, some don't

I have 6 Reolink cameras of various types, all connected via ethernet to Reolink NVR RLN16-410. Three show video in HA, others don’t. Added Bridge to Apple Home, then all cameras and get video from all (not streaming) in AppleHome. Monitor connected to NVR shows streaming live view from all cameras. All cameras seem to be configured the same in HA, all labeled ‘Fluent’ (whatever that means), all equipment has most current firmware. I’m stumped - any suggestions?
