Hi-tech cameras that can scan crowds for terrorists and shoplifters have beaten a trained Scotland Yard “spotter” in a unique test.
The facial recognition cameras picked out four out of six “faces” in a crowded station concourse but the human eye only spotted two of them.
Now makers of a new system called Face Alert say it has produced 98 per cent accuracy scores on moving targets in trials. BBC researchers pitted the system against Idris Bada, a civilian detention officer at Charing Cross police station who is one of a squad with exceptional memories for faces recruited to a team to identify theLondonrioters.
