Rule Description Applicable Scene
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 dened time,
an alarm is triggered, and then the
system performs congured 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.
Fast moving
When the motion speed is higher than
the congured speed, an alarm is
triggered, and then the system
performs congured 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 target stays over the
congured time, an alarm is triggered,
and then the system performs
congured alarm linkages.
Road monitoring and trac
management.
Crowd gathering
When the crowd gathers or the crowd
density is large, an alarm is triggered,
and then the system performs
congured 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 detection
When the target loiters over the
shortest alarm time, an alarm is
triggered, and then the system
performs congured alarm linkages.
After alarm is triggered, if the target
stays in the area within the time
interval of alarm, then alarm will be
triggered again.
Scenes such as park and hall.
Congure IVS rules. This section takes tripwire as an example.
