Wireless bidirectional people counting sensor SensMax Pro D3

Bidirectional people counter description

Wireless people counter SensMax Pro D3 designed for counting retail traffic in retail stores and medium-small shopping malls with option to detect visitor movement direction.

Bidirectional people counting gives you opportunity to detect how many people visited particular floor of the shopping mall, or how many visitors were inside the store.

Visitor counting system helps to track retail traffic statistics and to display it in various reports per hour, day, week, month and year. 


Why to choose wireless people counter sensor?

Wireless bidirectional people counters SensMax Pro D3 have easy installation that needs no special cabling works, like installing electricity or connectivity cables. Mostly this type of traffic counter device used for visitor counting solutions in shopping malls or any other complex premises where is need to detect visitors movement direction to calculate occupancy statistics or premises fulfillment by people.

Wireless people counters collect visiting statistics per IN/OUT movement direction and send this data to a data collector that forwards all statistics via local area network, internet or 3G connection to a central data base in HQ or SensMax cloud reporting portal. You can see both statistics per each movement direction separately, as well as summary of them that shows actual visitors were inside the premises. 

How wireless bidirectional people counter sensor works?

SensMax Pro D3 people counting sensor uses three infrared rays and advanced scanning technology to determine visitors’ movement direction. People counting sensor scans area 200 times per second, so movement direction detection is 94-98% accurate. It is wireless retail traffic counter device, so you can install it without any special cabling works in easy way by sticking to any surface at the entrance. 

SensMax Pro D3 wireless people counter battery life is 6-12 months depending on people traffic intensity. Front-end battery replacement is very convenient and can be done without people counting sensor removal. 

Bidirectional people counting system sensor stores each movement direction statistics separately into internal memory of the sensor that it is enough to store 25 days of hourly statistics for backup reasons.


Data from bidirectional people counting sensors automatically forwarding to HQ using SensMax TCPIP data collector via LAN/ Internet router, or 3G mobile network for projects where it is not possible to connect local IT infrastructure. Visitor counting system is fully automated and data updates happens each 20 minutes according to default settings. 

There are three modification of bidirectional people counters for various communication ranges. Please note differences and pickup best fit device for your project according to store or shopping mall size: 

  • SensMax Pro D3 – regular communication range up to 30-40m, 
  • SensMax Pro D3 LR – long range communication up to 150m in open space and up to 50m through walls, 
  • SensMax Pro D3 SLR – super long range communication up to 900m in open space and up to 150m through walls.
