A<->B: The object going across the line from both direcons can be detected and alarms are
triggered.

detected.
B->A: Only the object crossing the congured line from the B side to the A side can be
detected.
Sensivity
It stands for the percentage of the body part of an acceptable target that goes across the pre-
dened line. Sensivity = 100 - S1/ST × 100. S1 stands for the target body part that goes
across the pre-dened line. ST stands for the complete target body. The higher the value of
sensivity is, the more easily the alarm can be triggered.
Detecon Target
Human and vehicle are available. If the detecon target is not selected, all the detected
targets will be reported, including the human and vehicle.
Target Validity
If you set a higher validity, the required target features should be more obvious, and the
alarm accuracy would be higher. The target with less obvious features would be missing.
