Discover the case studies from our customers

As you can read from our case-studies below in which you will discover how our teams could meet each customer’s needs and issues, our know-how needs not be proved anymore.

CO / NO detection and smoke extraction coupling

For a real estate program including parking on two basement levels, Fern must build a ventilation system and look for a trusted partner to couple CO / NO detection to regulatory smoke extraction.

Detecting the pollution and air flow

We suggested in a private underground parking lot in Paris that all the devices for detecting the pollutants, for the servitudes and for the ventilation management controls should be replaced.

Air flow and energy economy

In order to improve the quality of the air in a garage, the ALHYSEES company wanted to control a fan as early as possible while optimising the energy consumption linked to this ventilation.

Car parking management

An airport contacted us so that we would provide a solution for plate detection when getting inside and outside of the parking lot which would also detect the cars making abusive usage of car parking.

Automatic License Plate Recognition

The deployment of an automated license plate recognition solution allows Migros Genève to solve its three parking management problems

Hesion helped Babcock Wanson to build a starting stock to carry out simplified standard exchanges, with many benefits
