Do your cameras randomly drop out for a few seconds saying "no signal detected' every few minutes?

All of my cameras are fine, but these two always dip out and say no signal detected after a few minutes. I can't seem to figure out why. Any ideas?
 
What cameras make/model.

It is possibly a wonky camera in BI that deleting it and re-adding it can correct (best case).

If you have SD cards in the camera, they could be failing and causing this.

Worse case is the power supply (like the POE switch) is starting to fail and BI is picking up on the that and will eventually fail.

I have experienced all of these LOL.

I don't think it's the switch, I just replaced it with a pretty heavy duty one rated way above what these cameras are meant for.

They're Reolink Duo 2's.

I know you guys hate Reolinks... but any help would be good.

Oh that explains it LOL.

Those are such new cameras and do things like splicing two images together into one and then with them not following normal ONVIF protocol, BI is probably interpreting it as no signal.

Does it actually No signal and you have no image or is it logging it as no signal but the image is still there? If it is the latter, just accept the bug.

In either case, probably need to send a request to BI support so they can look into it. it might be a simple coding fix hopefully.
 
The only time I've encountered that is with a bad cable on a Dahua camera and on a Reloink, even with a known good cable.

So it's actually both. The image will freeze on the screen for a period of time then it will say no signal randomly. They just sort of pop back and fourth every minute or so with a no signal.

Also, side note, what are the purple bells? I can't find their meaning anywhere in the BI manual with Ctrl F.

Yeah, reach out to support. They will probably want access to the camera to see if it is something in the code they can fix for that particular camera.

A new camera status “bell” icon replaces the trigger icon once an alert is confirmed. This helps to emphasize the difference between the “triggered” and “alerted” states—not all triggers become alerts based on filters and AI analysis.

oh neat. thanks. Okay sounds good.
 
Maybe try rolling back to an older version of BI....So maybe it'll play nice with the cams then.

You're essentially Beta testing with 5.6
 
I had a lot of signal lost errors awhile back and it turned out to be my switches could not handle all the traffic. After upgrading the switches to 1gb everything was fine. I found it by assigning my cams to groups which represented the switches - S1, S2, etc... By grouping them that way I could easily detect patterns using the BI Status window

I had this EXACT issue with my Duo II's. They would lose signal (only in BI, not in the Reolink App) 100-200 times/day. Dreg Mitch advised me to disable RTSP keel-alives for the camera. I made the change and have not had a signal loss since.

I experience this from time to time. I have discovered that Windows will change the Speed & Duplex setting in my NIC to 10 MB or slower. Changing this back to GB or better resolves the issue.
