COUNCILS USE BUGS IN LAMPPOSTS TO EAVESDROP ON YOU
A network of new “intelligent” listening devices which can monitor discussions has been deployed on Britain’s streets for the first time.
The so-called Sigard system has been tested in London, Manchester, Birmingham, Glasgow and Coventry. The microphones, connected to CCTV cameras, can recognise aggressive “trigger” words and sounds, then automatically direct cameras to zoom in on the speakers.
......
The microphones can listen in on conversations up to 100 yards away. The cameras then record both sound and images.
Manufacturers say Sigard can distinguish between distress calls, threatening behaviour and general shouting.
The system filters out background noise and focuses on suspect sounds.
Sigard systems are used widely in Holland, where 12 cities have fitted the microphones.
这么强大的Big brother系统估计很快就会在全球普世开来,呵呵。 以后说话得小心了。
