− Time Threshold: 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 threshold, device will trigger an alarm. Its range is [0s-2s]

value is, the more easily the detection alarm can be triggered. Its range is
[1-100].
− Percentage: The ratio of the in-region part of the object that can trigger
the alarm. For example, if the percentage is 50%, when the object enters
the region and occupies half of the whole region, device will trigger an
alarm. Its range is [1-100].
