Functions Description Scene
Tripwire
When the target crosses tripwire
from the defined motion
direction, an alarm is triggered,
and then the system performs
configured alarm linkages.
Scenes with sparse targets and no
occlusion among targets, such as the
perimeter protection of unattended
area.
Intrusion
When the target enters, leaves, or
appears in the detection area, an
alarm is triggered, and the system
performs configured alarm
linkages.
Abandoned
Object
When an object is abandoned in
the detection area over the
configured time, an alarm is
triggered, and then the system
performs configured alarm
linkages.
Scenes with sparse targets and without
obvious and frequent light change.
Simple scene in the detection area is
recommended.
●
Missed alarm might increase in the
scenes with dense targets, frequent
occlusion, and people staying.
●
In scenes with complex foreground
and background, false alarm might
be triggered for abandoned or
missing object.
Missing Object
When an object is taken out of
the detection area over the
defined time, an alarm is
triggered, and then the system
performs configured alarm
linkages.
Fast Moving
When the target moves fast in the
detection area, an alarm is
triggered, and then the system
performs configured alarm
linkages.
Scene with sparse targets and less
occlusion. The camera should be
installed right above the monitoring
area. The light direction should be
vertical to the motion direction.
Parking
Detection
When the vehicle stays in the
detection area longer than the
configured duration, an alarm is
triggered, and then the system
performs configured alarm
linkages.
Road monitoring and traffic
management.
Crowd
Gathering
When people gather and stay in
the detection area longer than
the defined duration, an alarm is
triggered, and then the system
performs configured alarm
linkages.
Scenes with medium or long distance,
such as outdoor plaza, government
entrance, station entrance and exit. It is
not suitable for short-distance view
analysis.
Loitering
When the target loiters over the
shortest alarm time, an alarm is
triggered, and then the system
performs configured alarm
linkages.
Scenes such as park and hall.
