Wireless People/Door Counting Technology
Counting Technologies offers highly-accurate infrared-based people counting solutions to gather valuable customer information. Active infrared (IR) measurement involves the use of a small sensor set which emits and detects an invisible beam of infrared light. The unit has an optical lens system and electronic circuits to emit a narrow beam of pulsed light from an infrared light emitting diode. The counter is a two-sided set, which allows lower power requirements resulting in longer battery life.
As a person walks through the beam, the light is absorbed and reflected. The beam is momentarily interrupted and a counter is incremented. Light modulation techniques ensure that the counting is more reliable and not affected by infrared light emitted from other sources, such as sunlight.
- Infrared counters typically cost between $300 and $700 per unit.
- Infrared counters are highly accurate for low to medium volume entrances.
- Infrared counters have virtually no maintenance required after installation.
- Infrared counters are more adept at reducing overcounting from children by adjusting the height of the counter
Directional Counting
The direction of a person's movement is determined using a dual-beam system. Using a dual-beam system, the unit can distinguish between one beam being interrupted prior to the second beam being interrupted. Non-directional counters are smaller and easier to mount at the entrances, but since the raw count must be cut in half, the accuracy of intra-day counts (i.e. 9:00 to 9:30 am) will decrease.
Directional counters will provide a more precise number during any given time interval, but if the traffic is primarily being looked at by management as a Daily Total, the non-directional counter should show a similar margin of error since all who entered the site also walked out during that day.

418 MHz Directional Counter
Counting Technologies has the only battery-operated, wireless directional counter. All other directional counters require electrical power. These counters have a 3-year battery life. Occupancy rate of a location can be monitored using dual-beam systems. An increasing number of fire districts are requiring businesses to know their occupancy at any given time, and remain in compliance with zoned fire codes.
