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
