The Covid-19 epidemic is an opportunity for French companies to demonstrate their technological know-how. How to ensure that employees working in the same warehouse or in the same office comply scrupulously and at all times the famous physical distance of two meters between each person? The Parisian start-up Invoxia thinks it has found a solution with the Spacing Companion, a beacon the size of a large USB drive, which starts blinking and beeping when it is approached too close to another identical beacon. Each employee must therefore be equipped to be notified automatically.

These tags do not take into account whether one is positive or not for the coronavirus, it is just an alert device to respect the rules of physical distancing.

To develop this product, Invoxia did not go far, but only adapted an existing product, its GPS Tracker, a low-consumption location tag, for vehicles or luggage, allowing them to be found in the event of theft. In its “anti-Covid” version, the device does not use GPS but Bluetooth. There is no localization and anonymity is preserved because it is not necessary to identify yourself to use it.

Another French innovation: the French company Outsight, specialized in 3D cameras for autonomous cars, offers an infrared laser camera capable of locating a person with fever in the middle of a crowd, detecting people without masks and measuring the distances between individuals in the context of measures to respect physical distance. The technological particularity of this solution is to be able to virtually “mark” a person, using a small red tag which is displayed above their silhouette on the video image, in order to allow an operator of the easily follow on a screen. The company Outsight specifies however that there is neither facial recognition nor identification of the people filmed by any means.


Designed for public places, such as airports, this camera is used in particular at terminal 2 of Roissy airport. Again, this is an existing device that has been adapted to the Covid-19 situation. At Roissy, the camera is only used to manage passenger flows to date, its “anti-Covid” features have not been activated.
