The recent terrorist attacks in the Brussels metro has revived the idea of an intelligent software to detect suspicious behavior. Defrost, an audio and video case, has already been tested by RATP.
How to detect suspicious behavior in public transport for example? The question arises of an even stronger way since the attacks in the metro in Brussels. Nearly 10,000 cameras already installed metro and RER Ile but new systems could be more efficient than simple video surveillance.
Researchers are working on the development of intelligent software. In June 2015, a device was tested on line 14 of the Paris metro. An audio and video box called Defrost (Detection and Incident Management in a railway vehicle) was used. This case analysis in real time for unusual behavior but for now, it is more vandalism and assault rather than terrorism. Difficult for researchers to work on the subject. Suspicious behavior in a crowd remains difficult to determine. As for data on a possible scenario of a terrorist attack, they are few and researchers do not have access to images to analyze attacks.
For 20 years as industrial thinking but the current context of counter-terrorism should accelerate the development of these tools. smart camera devices could go on the market within one to two years, say experts. For now, we do not know the exact cost but some embedded systems may return less than a thousand euros to equip a subway train car
