There are four unique sets of precise positioning
LEDs evenly distributed on the door panels,
showing the status of 33 detection zones, as

the detection zone turns on, and an alarm is
generated.
(No alarm is generated if the device is in mute
state.)
C. Infrared sensor
After being connected to a power supply, the
metal detector starts to work. When no person
or object passing through the device, the
infrared sensors stop alarming to avoid false
alarm and accurately count passengers and
