This article shows how to place sensors for optimal results.
Avoid moving Objects
Incorrect: The sensor is placed in the vicinity of moving objects (revolving door, escalator, opening/closing door).
Solution: Place the sensor further away from the moving objects.
Incorrect: Crossing people flows in the field of detection.
Solution: Move the sensor so as to only have one line of people flows in the field of detection.
Incorrect: Interference from sensors placed face-to-face closely to each other.
Solution: Place the sensors further apart.
Avoid too wide entrances
Incorrect: The sensor’s field of view does not cover the whole area to be detected.
Solution: Turn the sensor 45° or mount the sensor on the wall instead.
Avoid counting legs
Incorrect: Sensor is placed too low, it might detect and count extra movements from limbs.
Solution: Place the sensor at a height of 1.2m .
Correct: Each sensor only detects one people flow, there are no crossing people flows in front of a sensor.
