indicates vertical ruler, and indicates horizontal ruler
●
Select an added ruler, and click
to delete the ruler.
5. Set the global sensitivity.
Adjust the lter sensitivity. With higher value, it is easier to trigger an alarm when low-contrast
object and small object are captured, and the false detection rate is higher.
6. Enable Privacy Protection. After enabled, the human detected will be blurred by mosaic.
7. Click Apply.
Result
1. Select the verication type, and then click Calibration Verication.
To verify vertical ruler and horizontal ruler, respectively select Height Verication and Width
Verication.
2. Draw a straight line in the image to verify whether the rulers are correctly set.
In case of big dierence between the estimated value and the actual one, ne-tune or reset
parameters until the error requirement is met.
8.4.2 Rule Conguration
Set rules for IVS, including cross fence detection, tripwire, intrusion, abandoned object, moving
object, fast moving, parking detection, crowd gathering, and loitering detection.
Prerequisites
●
Select AI > Smart Plan, and enable IVS.
●
Select AI > Smart Plan > Global Cong to nish global conguration.
Background Information
For the functions and applications of the rules, see Table 8-7 .
Table 8-7 Description of IVS functions
Rule Description Applicable Scene
Tripwire
When the target crosses tripwire from
the dened motion direction, an alarm
is triggered, and then the system
performs congured 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
congured alarm linkages.
Abandoned object
When an object is abandoned in the
detection area over the congured
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
