4. Set parameters of the rule.
-
Sensivity
The higher the value is, the more easily the alarm can be triggered.
Target Detecon
You are recommended to select the target as Human & Vehicle. In distant view, the device
cannot classify the target with pixels less than 10*10. The target will be recognized as
human directly. So the
selecon of this item will not trigger false alarm or missing alarm.
Background Interference Suppression
Eliminate the environment interference to reduce the false alarm. For example, the wind
blows grass.
5. Draw the rules.

When the rule type is selected as Line Crossing, click to draw a line in the live view. You
can drag end points of the line to adjust the posion and length.

Note
Draw three segments of the rule from near to far to cover all of the detecon area.
6. Check to enable Filter by Pixel. Then Draw max size and min size rectangles to lter the target
among human, vehicle, animal, and others. Only the target whose size is between the Max. Size
and Min. Size value will trigger the alarm.
