1) Threshold: Range [1s-10s], 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 set time, the alarm will be triggered.
2) 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.
3) Percentage: Range [1-100]. Percentage defines the ratio of the in-region part of the
object which can 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.
