can be detected.

Sensivity It stands for the percentage of the body part of an acceptable target that goes

across the pre-dened line. Sensivity = 100 - S1/ST × 100. S1 stands for the

target body part that goes across the pre-dened line. ST stands for the complete

target body. The higher the value of sensivity is, the more easily the alarm can
