the device can take linkage acīons.
Steps

2.
Check Enable.
3.
Select one Region. For the region seī«ngs, refer to Draw Area .
4.
Set the detecīon target, sensiīvity and the target validity.
Sensiīvity It stands for the percentage of the body part of an acceptable target that goes
across the pre-deī®ned region. Sensiīvity = 100 - S1/ST Ć 100. S1 stands for
the target body part that goes across the pre-deī®ned region. ST stands for the
complete target body. The higher the value of sensiīvity is, the more easily
the alarm can be triggered.
Detecīon
Target
Human and vehicle are available. If the detecīon 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.
