Parameter
Note
Name
It is to modify the region name, which is used to identify different
regions.
Sensitivity
The bigger the sensitivity is, the easier it becomes to trigger motion
detect, but meanwhile it increases false alarm rate, it is advised to
use default value.
Threshold
It will trigger alarm when the target covers a higher percentage of
the detection area than the value which has been set. For
example, set threshold as 10, the moving target covers more than
10% of the total detection area, and then it will trigger alarm.
The bigger the threshold is, the more difficult it is to trigger motion
detection.
