Pedestrian counter for occupancy monitoring in retail stores, supermarkets and public spaces.

BEA’s LZR-SIGMA utilizes highly precise, LASER-based technology that counts shoppers entering and exiting the store. With our online occupancy dashboard, you can easily set maximum occupancy thresholds and review count data.

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 250-dot 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.

Mount It anywhere

Our solutions fits into any building environment. Three different mounting accessories create a flexible solution that can be placed on/in ceilings, on walls, near doors or anywhere accurate counting is needed.
