Wireless people counter SensMax Pro D3 Long Range people counting in retail stores and medium-small shopping malls. This type of people counting sensor has radio module with extended connectivity range up to 150m. Bidirectional counting algorithm detects visitors movement direction In or Out.

Bidirectional people counter SensMax Pro D3 LongRange is a wireless people counting device with a powerful radio module with extended communication range up to 150m. This type of sensor can detect visitor movement direction IN and OUT. Bidirectional counting shows you how many people visited a shopping mall or a big store through the main entrance, floor by floor, or particular zone. The extended communication range allows using one data gateway for many people counting sensors.

This people counter device is battery powered. Battery life is up to 1 year. People counting sensor scans area 200 times per second, therefore counting accuracy is high up to 94-96%. This type of sensor has a built-in memory for data backup of hourly data per 25 past days.


wireless people counting bidirectional count how it works


Wireless people counters create an invisible infrared barrier using three rays for movement direction detection. Bidirectional people counting algorithm: one crossing IN = +1 visitor and one crossing OUT = -1 visitor. You can see both stats per each direction and a summary report of two movement directions. The difference between them shows the number of people inside the premises. People counter collects statistics automatically for 24/7 and deliver it to the central database using a data gateway every 20 minutes. There are two types of data gateways LAN/Internet or WiFi internet, as well as two types of software - cloud-based or client-server. People counting system provides various ready to use reports per hour, day, week, month, year. You can find people counting software features comparison here.
