To define intrusion detection:
1. From the menu toolbar, click Configuration > Events > Intrusion Detection .
2. Check the Enable Intrusion Detection checkbox to enable the function.
3. Click Draw Area , and then draw a rectangle on the image as the defense region.
When you draw the rectangle, all lines should connect end-to-end to each other. Up
to four areas are supported. Click
Clear to clear the areas you have drawn. The
defense region parameters can be set up separately.
Note: The area can only be quadrilateral.
4. Choose the region to be configured.
Threshold: This is the time threshold that the object remains in the region. If you
set the value as 0, the alarm is triggered immediately after the object enters the
region. The range is between 0 and 100.
Sensitivity: 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. The range
is between 1 and 100.
Percentage: This defines the ratio of the in-region part of the object that can trigger
an alarm. For example, when you set the percentage as 50%, half of the object
entering the region will trigger the alarm. The range is between 1 and 100.
5. Click Edit to set the arming schedule for the alarm input. See “Motion detection
alarms” on page 26 for more information.
6. Specify the linkage method when an event occurs. Check one or more response
methods for the system when an intrusion detection alarm is triggered.
