Smart mobs & camera
Tiré du blog *Smart mobs*, quelques lignes sur les caméras de surveillance dans l'espace public:
This USA Today article says that in "U.K. public places, smarter closed-circuit TV cameras have been given the ability to listen for disturbances and also keep an eye on citizens.The system has already been put into use in the Netherlands to listen for people speaking in aggressive tones, to try to counter violent attacks in Dutch streets, prisons and railways.
The aggression detector has been fitted to CCTV cameras on the streets of Groningen and Rotterdam in the Netherlands. In the U.K., London police also are considering installing the system, said Derek van der Vorst, the director of Sound Intelligence, the company that created the technology.The system works by putting microphones in CCTV cameras to continually analyze the sound in the surrounding area. If aggressive tones are picked up, an alarm signal is automatically sent to the police, who can zoom in the camera to the location of the suspect sound and investigate the situation".
