Verification
Step 1 Select the verification type, and then click
Calibration Valid
.
To verify vertical ruler and horizontal ruler, respectively select
Height Verification
and
Width Verification
.
Step 2 Draw a straight line in the image to verify whether the rulers are correctly set.
In case of big difference between the estimated value and the actual one, fine-tune or
reset parameters until the error requirement is met.
5.8.2 Rule Configuration
Set rules for IVS, including cross fence detection, tripwire, intrusion, abandoned object, moving
object, fast moving, parking detection, crowd gathering, and loitering detection.
For the functions and applications of the rules, see Table 5-6.

Rule
Description
Applicable Scene
Tripwire
When the target crosses tripwire from
the defined motion direction, the
system performs 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, the
system performs alarm linkages.
Abandon
ed object
When an object is abandoned in the
detection area over the set time, the
system performs 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,
the system performs alarm linkages.
Fast
moving
When the motion speed is higher
than the configured speed, the
system performs 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
configured time, the system performs
alarm linkages.
Road
monitoring
and
traffic
management.
