This is the time threshold that the object remains in the region. If the
value is set as 0, the alarm is triggered immediately after the object enters the
region. The range is between 0 and 100.
Sensitivity:
The sensitivity value defines the size of the object that can trigger the
alarm. When the sensitivity is high, a small object can trigger the alarm. The range
is between 1 and 100.
Percentage:
This defines the ratio of the in-region part of the object that can trigger
an alarm. For example, when the percentage is set as 50%, half of the object
entering the region will trigger the alarm. The range is between 1 and 100.
