In order to collect foot traffic data, the F21 sensor must be mounted for optimal accuracy.
A good mount means:
The F21 sensor is centered above the entryway
The edge of the F21 sensor is in line with the edge of the doorframe
There is nothing blocking the F21 sensor's view
The sensor will not collect accurate data if:
The sensor is not top-mounted on the entryway
The sensor is not centered on the doorway
The edge of the sensor is not in line with the edge of the doorframe.
The sensor's field of view is blocked by an obstruction
The sensor has been painted or altered from its original state
