Abandoned Object
Abandoned object means the system will trigger alarm if the abandoned object in the monitoring scene
exceeds the time which has been set by the users.
Abandoned object and missing object can be confusing in a situation where both foreground and
background are complicated.
It also triggers alarm as abandoned object if there is pedestrian or vehicle staying still for too long. In
order to filter this kind of alarm, generally the abandoned object is smaller than people and vehicle;
therefore it can filter the people and vehicle via setting size. Besides, it can avoid the false alarm caused
by short stay of people via extending alarm time properly.
Application scene: It can be applied to the scene where the target is sparse and there is no obvious and
frequent light change. False alarm will be increased in the scene with high target density and frequent
blocking; false alarm will be increased in the scene where there are more people staying. As for the
detection area, try to make it simple, the function is not suitable for the area which is too complicated.
