I've set up my MV71 motion alert with "Minimum event duration for trigger" and "Sensitivity" because it sends too many alerts even it seems not that much when I review it through dashboad.
My question is if I setup "duration for trigger", how often it triggers the event. Let's say I set "10 seconds" for "duration for trigger", what happened if the object in the camera still moving after 10 seconds?
Do I get an alert every seconds after 10 sec? or I get an alert every second after first alert? or I only get once and no more alearts for a while?
I'm not sure, but I think it uses the same logic it also uses for motion search. So if there is continuous movement it would register as a single motion event. That said, no algortithm that does this will be flawless. So I think the real behavior will lie somewhere in between. You won't get an alert every 10 seconds, but sometimes a single event of longer duration might trigger multiple alerts.
Again, I'm not sure, but I think that'll be the behavior.
Thank you for your reply. What you are saying is very similar to the actual behavior which I get several alerts when an object is continually moving around. However I'd like to confirm the behavior of motion alert feature. So I will open a case and ask them detail.
