SIGMA is an all-in-one people counting solution.

BEA’s SIGMA is  made up of a highly precise, laser-based sensor. It sets up via your smartphone. With our online device management, you can easily manage multiple sensors, at multiple locations.

SIGMA laser technology

Independent of light variations and weather conditions, the SIGMA’s laser time-of-light technology guarantees an accurate counting system, whatever the environment.

High precision, autonomous and a lot more

SIGMA provides better data wherever you need it. Inside, outside, even in extreme weather conditions. Discover the advantages of a precise technology in all the situations.

  • High precision

    A 11250 laser dots (per second) detection field accurately, and anonymously, detects adults and children, whether in groups or individually.

  • Day or Night, Light or Dark

    Time-of-Flight technology works regardless of time-of-day conditions. The SIGMA operates independently of lighting conditions for accurate counting, 24/7.

  • Indoor/outdoor installation

    Even in extreme weather (rain, fog, snow) the laser technology performance remains completely stable. The SIGMA is IP53 rated to ensure performance in indoor and outdoor settings.

  • Autonomous connectivity

    Delivered with a cloud-based connectivity, the people counter can be completely independent from a local network and its cabling and system constraints.
