A survey of North American citizens has revealed that the majority of people would prefer their children's schools to be protected by a CCTV system.
The Ipsos Public Affairs research, which polled 1,000 people in both the US and Canada, found that 60 per cent of Americans and 52 per cent of Canadians said that surveillance cameras would make schools safer.
Only 30 per cent of people in the US and 11 per cent in Canada thought that armed guards in schools would be an effective way of keeping schoolchildren safe.
Furthermore, 54 per cent of US adults polled said they are more concerned about their children's safety while they are at school than they were 12 months ago, while 40 per cent of Canadians stated they are now more worried.
Research from the UK suggests that around nine out of ten schools use CCTV in some way.
