Which model number / version are you using? Headlights are common source of false alarms generally but newer versions of video analytics have often improved on this.
I have to say I get very few false triggers from lights on my 5442's, and the SD6AL445XA-HNR-IR PTZ has been rock solid amazing with regards to false alerts... REVIEW: SD6AL445XA-HNR-IR 4MP 45x Starlight IR AI PTZ
PTZ set for humans only- very busy 4 lane road
5442 same location, zig-zag tripwire set to Human only
I can’t read French but I think that message is telling you that Smart Motion Detection (SMD) will no longer work if you disable regular MD, which is correct, they are tied together. You don’t want either.
ok thank you i note for the photos i will take screenshot for the next few times and i didn't know that we could just select the ivs i will test again ;-)
