Select the <Camera> to configure the VCA.
You can check the checkbox of
<Save VCA Picture> to save the captured pictures of the VCA
detection.

6.
Click the
<Rule Settings> button to set the intrusion detection rules. Set the following
parameters.
1)
<Threshold>:
Range [1s-10s] – this is the threshold for the time of the object loitering in
the region. When the duration of the presence of the object within the defined detection
area is longer than the set time, the alarm will be triggered.
2)
Drag the slider to set the detection sensitivity.
<Sensitivity>:
Range [1-100]. The value of the sensitivity defines the size of the object
which can trigger the alarm. The higher the value is, the more easily the detection alarm
can be triggered.
3)
<Percentage>:
Range [1-100]. This defines the ratio of the in-region part of the object
which can trigger the alarm. For example, if the percentage is set as 50%, the alarm is
triggered when the object enters the region and occupies half of the whole region.
