duration of the object in the defined detection area is longer than the set time, the alarm will be
triggered.
2) Click-and-drag the slider to set the detection sensitivity.
Sensitivity: Range [1-100]. The value of the sensitivity defines the size of the object which can trigger
the alarm. The higher the value is, the more easily the detection alarm can be triggered.

trigger the alarm. For example, if the percentage is set as 50%, when the object enters the region and
occupies half of the whole region, the alarm is triggered.
