This Guardian article says “something funny has been happening to the CCTV cameras in our neighbourhood. They have started growing ears. Not real ones - at least not yet - but audio functions enabling them to “hear” what is happening around them as well as see. At the moment the experiment is confined to six cameras operating in the Soho area of Westminster, London, which has a high concentration of clubs and bars. An advanced wireless network which the council is building relays the information to a monitoring centre”.
