I'm getting odd false IVS alerts and can't figure out why. This happens with a new T5442T-ZE that I put up and previously with a T5842T-ZE in the same location. So seems to be something about the scene and/or how I'm doing things but don't know what that might be.
More specifically what's happening is that at random times (day, night, in between) I get a series of 3 IVS alerts. Sometimes just 1 or 2 but most often it's a cluster of 3 about a minute apart. Happens probably 3 or 4 times every day. There's never anything that I've seen that should be triggering (with one exception shown below which did not actually trigger an alert).
This is the scene:
Kind of overkilled with tripwires/intrusion while trying to test to see what was triggering but the same happens with a much more simple set of rules. I've left the live view up on a second monitor to try to watch what's happening when I get the alerts. In this particular case, it appeared to want to trigger on the light post BUT it did not flash and did not actually generate an alert. I suppose not enough confidence or not moving or whatever. But this was the only time that I've ever seen anything turn red so I captured it. Other than this one time, when I get the alerts I see nothing ever turn red.
This is the only location where I have any false alerts like this with Dahua IVS. The positive side works great. Always triggers for a human. I can see whatever lines turn red and flash and alerts go through fine. I can have IVS alternately set to no target, human, vehicle, combination and the same happens.
I've confirmed that's the only motion detection that should be turned on in the cam. I'm not running Deep Stack. BI's motion detection is off and the triggers come as externals. Not running anything else to trigger. I can have the shadows from the tree moving like crazy and no alerts. A completely quiet, static scene and alerts.
Any ideas?
