Detecon Target
This funcon allows alarm triggering by specied selected target types. If the detecon target
is not selected, all the detected targets will be reported.
Note
This funcon is only available for certain device models under certain sengs. Please refer to
the actual sengs.
Sensivity
It stands for the percentage of the body part of an acceptable target that goes across 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.
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.
