Sensitivity: It is used to set the size of the control target object. The higher the sensitivity, the easier
the object is judged to be the target object. The lower the sensitivity, the larger the object will be
judged as the target object. The sensitivity can be set in the range of 0 to 100.
Time Threshold (s): An alarm is generated after the target enters the warning zone for a continuous
dwell time. If the time threshold is set to 5 seconds, the target intrusion zone is triggered for 5
seconds. The range is 1 to 10 (seconds).
