Sensitivity
The higher the value is, the more easily the alarm can be triggered.
Target Detection
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 selection 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.

The device performs perimeter protection when the target stays in the detection area for
more than set value.
