Now they can hear you as well
POLICE in the United kingdom are considering monitoring conversations in the street using high-powered microphones attached to CCTV cameras.
The microphones can detect conversations 100 yards away.
The equipment can pick up aggressive tones on the basis of 12 factors, including decibel level, pitch and the speed at which words are spoken. Background noise is filtered out, enabling the camera to focus on specific conversations in public places.
If the aggressive behaviour continues, police can intervene before an incident escalates.The devices are used at 300 sites in Holland already.
There are more than 4.2 million CCTV cameras, and the average person is filmed more than 300 times a day.
