From the Daily Mail:
Britain's first 'talking' CCTV cameras have arrived, publicly berating bad behaviour and shaming offenders into acting more responsibly.
Littering, bikes in pedestrian areas, and other anti-social behaviors are being targeted. Don't worry, though:
The control room operators have been given strict guidelines about what commands they can give. Yelling 'Oi you, stop that', is not permitted.
'We always make the requests polite, and if the offender obeys, the operator adds 'thank you'. We think that's a nice finishing touch."
Camera-happy Brits also learned today that it's easy to avoid getting caught speeding by smart cameras--all they have to do is change lanes.
