What is Time of Flight Technology and How Does it Work?

Time of Flight sensors work by emitting very short infrared pulses of light. By measuring the time it takes for these infrared light pulses to bounce back to the sensor, the device can produce an incredibly accurate distance map of the environment underneath. Objects and people can be tracked as they pass by – allowing the sensors to be a very accurate measure of footfall.


Time of Flight people counters are the most accurate automated people counting solution available. They are unaffected by changes in light, temperature or humidity. Expected accuracy rates of these automated people counters are 99%.

Key Features

Staff Detection

Staff can be excluded from any count data – or counted specifically.

Children Detection

A rough idea of adult and children numbers can be obtained by recording height measurements.

Works in Darkness

The counters are unaffected by different light levels, patterned flooring, or reflective surfaces.


No personal data is gathered. Customers and staff are not personally identifiable.


Multiple counters can be linked together to cover very wide entrances.
