The head of a campaign group has raised concerns about the number of schools that use CCTV cameras. Director of Big Brother Watch, Nick Pickles, said: “This research raises serious questions about the privacy of schoolchildren across Britain, with some schools having one camera for every five pupils.” Almost one in 10 of the schools which use CCTV said cameras were positioned in such locations as changing rooms, while 54 have more than one camera for every 15 students.
