Big Brother will be taking his place at an elite secondary school next month. Closed-circuit television is to be installed at St Paul's College in Bonham Road, Mid-Levels, to ensure staff and student security. The move, which will cost tens of thousands of dollars, is rare. One camera will be installed on the roof of the boys-only school, giving a full view of the playground. Another two are being installed in the locker room on the second floor, next to the changing room. The Human Rights Monitor group said the school would have to handle the matter with great care. But principal Timothy Ha Wing-ho denied the cameras would infringe rights. 'It's nothing to do with human rights. The cameras are only for security reasons,' said Mr Ha. 'If there are accidents in the playground or any thefts in the locker room, teachers will know through the CCTV. The cameras are to protect the students. 'The cameras in the locker room will be installed with fixed-focus lenses. 'Only students opening or closing their lockers will be filmed, not the boys changing clothes.' He said each year the school had a few cases of lost property. The idea came from parents concerned about safety. He said the closed-circuit TV would be connected to the staff room so teachers could monitor the screens. Human Rights Monitor director Law Yuk-kai said information obtained through closed-circuit TV had to be handled with care. 'We believe children enjoy the same human rights as adults. But we accept that sometimes something has to be done to protect youngsters. In this case it's not easy to say whether the school is right or wrong. 'But the school must always stick to its purpose in installing closed-circuit TV. If the cameras are for security, the information obtained must be used in the security area,' he said. Teachers should not use any film of playground activities to discipline students, Mr Law said.
