1) Draw a detecon area. Click , click on the live view to specify the vertexes and draw the
boundaries of the detecon area, and right click to complete drawing.
2) Set the minimum size and the maximum size for the target to improve detecon accuracy.
Only targets whose size are between the maximum size and the minimum size trigger the

Threshold
Threshold stands for the threshold for the me of the object loitering in the region. If the
me that one object stays exceeds the threshold, the alarm is triggered. The larger the value
of the threshold is, the longer the alarm triggering me is.
Sensivity
Sensivity stands for the percentage of the body part of an acceptable target that enters the
predened region. Sensivity = 100 - S1/ST × 100. S1 stands for the target body part that goes
across the predened region. ST stands for the complete target body. The higher the value of
sensivity is, the more easily the alarm can be triggered.
