Detection Target
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 false
alarms caused by wind blowing grass.
