Cameras, algorithms… and black screens. In Massy, a rather quiet town in Essonne, video operators no longer waste time in front of their screens. “When I want to know something, I launch a scenario and then I analyze the results,” explains Régis Lebeaupin, responsible for video protection at the municipal police.
“We had, in a city street, always the same problem: users who regularly take a prohibited direction, continues the agent. CCTV enabled us to identify that they were employees of the same company and that it always happened at arrival and departure times. Rather than being repressive, we sent word to the management of the company. »
With conventional video surveillance, it would have been necessary to spend hours in front of the cameras. “There, I simply entered some information into the software before leaving and, the next day, retrieved all the information that interested me,” says Régis Lebeaupin.
Real-time detection of unauthorized dumping, management of prohibited directions, detection of raiding, monitoring of intrusions into municipal buildings… At the Massy urban supervision center, each problem has its own algorithm. The city, a long-time user of video surveillance, has been using image analysis tools from XXII, one of the most important French start-ups in this booming sector, for a year. Technologies similar to facial recognition, with the difference that they do not analyze biometric data, with a legal status that is currently unclear.
“To fully understand, you have to go back two years,” rewinds Franck Rougeau, deputy mayor in charge of economic development and innovation. The observation is simple. The city had, at the time, 200 state-of-the-art cameras, bought at exorbitant prices but largely underused. “We wondered how to optimize? Going through artificial intelligence, ”continues the chosen one.
Two ideas are already there. Having a tool that goes beyond the security framework and capable of allowing the feedback of reliable information in real time. Franck Rougeau, an entrepreneur, is moving towards XXII, whose CEO, William Eldin, has in the past founded Coyote, one of the most widely used mobile speed camera detection applications in Europe. “A year later, it’s a tool we no longer want to do without,” points out the elected official.
“This is a real tool for streamlining the work of the municipal police, continues Régis Lebeaupin, for example by controlling traffic at specific times rather than continuously. But it is above all a local policy tool because it allows us to respond concretely, quickly and in an informed manner to the concerns raised by our constituents, thanks to the sensors which are optimized. »
Easily customisable, automated video protection, as it exists in Massy, is now used as an information and decision-making tool for all city departments. “After confinement, the technical services had to decide if we wanted to keep the cycle paths open during the Covid, remembers Régis Lebeaupin. XXII’s technology allowed us to precisely analyze their attendance without having to assign an operator to view the images or send someone to count in the field. »
A transversal approach that goes beyond protection or technical services. Thus, in the service of heritage, artificial intelligence makes it possible to detect anomalies, such as forgotten lighting. In sport, it is used to quantify the number of people present at major events in order to better organize their supervision. “It’s a transversal approach, a real video management”, sums up Franck Rougeau.
Every six months, XXII’s software is updated to offer new features. Another should take place in the coming weeks and includes an image analysis algorithm capable of identifying fire outbreaks in real time.

75% of working time has been saved by video operators in front of Massy CSU screens since the installation of the software suite offered by XXII. “By automating certain actions without added value, we limit wasted time, ensure better quality of city services and professional well-being for officers,” points out Régis Lebeaupin, video protection manager at the municipal police.

“Image analysis responds to human limitations”
“Cities occupy a special place in the world of video protection. They are among the rare actors to have operators permanently in front of video walls. We know that, from 25 simultaneous images in front of an operator, they become a screen background. Image analysis tools respond to this human limit by submitting to the operator’s gaze those that deserve to be looked at.
Rather than constantly monitoring a camera overlooking an emergency exit, the operator will only take a look at it when an alert is displayed, for example if someone tries to break in. Similarly, existing technologies make it possible to identify and resolve many problematic situations: gathering on the public highway, vehicles in the wrong direction, raiding, etc.
