I know this is an old Thread, but did not want to start a new one.
Somehow a few months ago I noticed my Thermal CAM getting NoSignal in the Logs. I actually saw the Thermal Lens (Live Feed) show No Signal. Then the Visual Lens did the same thing a few seconds later. This would happen within about 5 minutes intervals. Over the past few months I would periodically watch it, could not put my finger on exact times. Went to the Camera's settings and could not figure out what changed. It worked fine prior.
I did a continuous ping test a few different times to the Camera and not one drop signal, steady 1 to 2ms
Ended up adding another Camera (Doorbell POE) and noticed the same NoSignal issue. Nothing in it's setting stood out either.
Was this from a Windows update? No
BI update since last year my subscription expired.
I do see the loss signal, skipped part in the recorded videos in BI.
Any suggestions be appreciated. Both CAMs are RTSP feeds and I have stay alive on them, tried unchecking and no difference...
