Intrusion detection
Intrusion detection allows you to set up an area in the surveillance scene. If
someone enters the area, a set of alarm actions can be triggered.
Figure 12: Intrusion Detection menu
To define intrusion detection:
1. Click Configuration > Smart Event > Intrusion Detection.
2. Check the Enable Intrusion Detection check box to enable the function.
3. Click Draw Area, and then draw a rectangle on the image as a defense
region. When you draw the rectangle, all lines should connect end-to-end to
each other. Up to four areas are supported. You can click Clear to clear the
areas you have drawn. The defense region parameters can be set up
separately.
4. Configure the settings of threshold, sensitivity.
Threshold: Range [0 to10 s]. This is the time threshold of the object to loiter
in the region. If you set the value as 0, an alarm is triggered immediately
when the object enters the region.
Sensitivity: Range [1 to 100]. The sensitivity value defines the size of the
object that can trigger the alarm. When the sensitivity is high, a small object
can trigger the alarm.
Percentage: Range [1 to 100]. This defines the ratio of the in-region part of
the object that can trigger an alarm. For example, when you set the
percentage to 50%, half of the object entering the region will trigger the alarm.
