Technology Laser


SIGMA provides a all-in-one people counting solution. It is made up of a laser based sensor, a device management platform and a mobile app to create peace of mind.


Accurate technology

Independent of light variations and weather conditions, the laser time-of-light technology guarantees an accurate counting system, whatever the environment.
Thanks to its high resolution detection field (250 dots per curtain), the people counter offers a reliable counting solution that accurately identifies adults, children and groups of people.

Independent of light conditions

Our laser technology is totally independant of light conditions. You can now also count with high accuracy in dark or bright places.

Indoor/outdoor installation

Even in extreme weather (rain, fog, snow), the laser technology performance remains completely stable. SIGMA is also IP53, which means you can install it inside or outside.

Coverage of large passages

You can define the counting field with precision and pair multiple SIGMA sensors to cover a wide area.
