c. Set the Time Threshold (Seconds) and sensitivity of the rule.
Sensitivity: 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).
d. Click Draw A Quadrilateral, and then move the mouse to the preview screen and click the left
mouse button in sequence to draw the endpoints of the quadrilateral warning zone to complete

linkage is triggered.
