The skies could soon be filled with the buzzing of thousands of tiny spy drones trained to snoop on British streets, the Home Office has warned.
They are one of a number of futuristic snooping techniques that could become reality including CCTV that recognises faces and cameras in the back of taxis.
The warning comes as the Pentagon revealed it is pumping hundreds of millions of dollars into new drone technology such as the ‘nano-hummingbird’ – a tiny remote helicopter equipped with video and audio equipment that can record sights and sounds.
Ministers said that advances in technology have meant such hi-tech measures are now possible and could soon be ubiquitous across the country.
The suggestions came in a proposed code of practice drawn up to help regulate the spread of CCTV, that will be overseen by a newly appointed Security Camera Commissioner.
