Step 6 Follow the steps to set the detection rules and detection areas.
1) Select a Virtual Panel to configure. Up to 4 virtual panels are selectable.
2) Drag the sliders to set Time Threshold, Sensitivity, and Percentage.
− Time Threshold: The threshold for the time of the object loitering in the
region. When the duration of the object in the defined detection area is
longer than the threshold, device will trigger an alarm. Its range is
[1s-10s].
− Sensitivity: The size of the object that can trigger the alarm. The higher
the value is, the more easily the detection alarm can be triggered. Its
range is [1-100].
− Percentage: The ratio of the in-region part of the object that can trigger
the alarm. For example, if the percentage is 50%, when the object enters
the region and occupies half of the whole region, device will trigger an
alarm. Its range is [1-100].
3) Click Draw Region and draw a quadrilateral in the preview window by specifying four
vertexes of the detection region.
