A people counter can be anything from a simple manual counting clicker to a highly sophisticated automatic counter.
- Manual counter - a person stands by an entrance and uses a clicker to count people in/out over a period of time. Expensive, time consuming and questionable reliability.
- Beam break counters - simple devices mounted on the side of entrances and count how many times a beam across the entrance-way is broken. Technically simple but very inaccurate when busy or counting groups/families.
- Video counters (mono video, stereo video) - these devices are mounted above entrances and use video analysis to count people. In well lit conditions, accuracy is good, however many end users and customers have concerns over privacy.
- Thermal counters - use advanced thermal arrays to detect the presence and movement of people by tracking their body heat. An anonymous solution, this method has a similar accuracy to video counters.
- Infrared counters - mounted above the entrance-way, these devices use infrared light to accurately count people moving in and out. By using infrared light, privacy of everyone coming and going is protected as no personally identifiable information is captured. Accuracy is extremely high, in excess of 99%.
Irisys specialise in thermal and infrared counters. Both offer high accuracy and both do it anonymously, protecting privacy.
