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