Sensivity Sensivity stands for the percentage of the body part of an acceptable target
that enters the pre-dened region. Sensivity = 100 - S1/ST × 100. S1 stands
for the target body part that goes across the pre-dened region. ST stands for
the complete target body. The higher the value of sensivity is, the more
easily the alarm can be triggered.
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.
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.
