Although crime statistics point to the fact that law-and-order issues are actually less of a problem now than in the past, the general public's perception remains one convinced that muggery and buggery hides behind every street corner. Politicans and the media stoke these fears, and we get hastily made laws and policies enacted as a result. Over in the UK, the trend over the past two decades has been to abrogate day-to-day policing of the streets to an army of CCTV cameras. Soon, if scientists have their way, the cameras will be able to train their focus on suspicious sounds automatically with new AI technology.
Researchers from the University of Portsmouth in the UK are working on refining AI software that currently allows the cameras to identify visual patterns associated with law-breaking. The plan is to add an audio capability, so that the noise of breaking glass (for example) would cause the camera to take notice and alert an operator. Eventually it is hoped that the AI software would be even more sensitive, according to Dr David Brown, one of the researchers, speaking to the BBC: "Later versions will get cleverer as time goes on, perhaps eventually being able to identify specific words being said or violent sounds."
