CCTV that can automatically monitor criminal behaviour and track suspects is being developed by UK scientists.
Researchers at Kingston University have created a system that uses artificial intelligence to recognise specific types of behaviour, such as someone holding a gun.
The technology is capable of following a person across multiple cameras.
Privacy campaigners warned that it might be used to target groups such as political protesters.
However, the developers insisted that their invention would allow police to focus on law breakers and erase images of innocent civilians.
The technology works by teaching a computer to recognise specific types of public behaviour, known as “trigger events”.
“In riot situations, it could be people running – a crowd might converge in a certain place,” said Dr James Orwell of Kingston University
“If somebody pulls out a gun, people tend to run in all sorts of directions. These movements can be detected.”
When an event is triggered, the software collates video footage from before and after the incident to record a full history of the suspect’s movements.
“If a window was smashed and shop looted in a town centre street, the technology would trace back to see who smashed the window and then retrace his steps to see when and where he entered the town centre.
“The technology would also trace where the man had gone after leaving the scene,” said Dr Orwell.
