2. Check the checkbox of Enable to enable the function.
3. Select a region number from the drop-down list of Region.
Region: A pre-defined vertexes area on the live view image. Targets, such as,
people, vehicle or other objects, who enter and loiter in the region will be
detected and trigger the set alarm.
4. Click Area Settings tab and click Draw Area button to start the region drawing.
5. Click on the live video to specify the four vertexes of the detection region, and
right click to complete drawing.
6. Set the Max. Size and Min. Size for valid targets. Targets smaller or larger than
the valid target size are not able to trigger detection.
Max. Size: The maximum size of a valid target. Targets with larger sizes would
not trigger detection.
Min. Size: The minimum size of a valid target. Targets with smaller sizes would
not trigger detection.
7. Click Stop Drawing when finish drawing.
8. Set the time threshold for intrusion detection.
Threshold: Range [0s-10s], the threshold for the time of the object loitering in
the region. If you set the value as 0, alarm is triggered immediately after the
object entering the region.
9. Drag the slider to set the sensitivity value.
Sensitivity: Range [1-100]. It stands for the percentage of the body part of an
acceptable target that goes across the pre-defined line.
Sensitivity = S1/ST*100
S1 stands for the target body part that goes across the pre-defined line. ST stands
for the complete target body.
Example: if you set the value as 60, the action can be counted as a line crossing
action only when 60 percent or more body part goes across the line.
Note: The Sensitivity of the detection is supported by certain models. Refer to
actual display for details.
