4.4.4.1.3 Abandoned Object
It means triggering alarm when the abandoned object exceeds the time set by users in the monitoring
scene.
Abandoned and missing object detection can be confusing in a situation where foreground and
background is both very complex.
It will trigger alarm when pedestrians or vehicles stay still for a long time, which is considered as
abandoned object. In order to filter this kind of alarm, generally the abandoned object is smaller than
person and vehicle; therefore it can filter person and vehicle via setting filter size. Besides, it can avoid
false alarm of short stay for people via extending alarm time.
Application scene: It can be applied to the scene where the target sparse and there is no obvious and
frequent light change. As for the scene with high target density and frequent blocking, alarm leakage will
increase; as for the scene with more people to stay, false alarm will increase. As for the detection area,
it is required to be simple; it can’t be applied to complicated areas.
The config steps are shown as follows:
Step 1
Select rule type as “Abandoned Object” and the config interface will be shown in Figure 4-87.
