Islamabad(WebDesk): School is a place where you meet number of children with different attitudes.Some children have habit to disturb others with their Crazy attitude.But now a caution for this kind of children.

In  couple schools England a trial of body cameras is being operated, with teachers using the threat of their behaviour being recorded and potentially used as evidence to try to calm down the most disruptive of children.

At least two secondary schools in England have been give the go-ahead to use the devices by their local education authorities. They're similar to the ones worn by many police officers, only, as a weird extra threat to the kids, they announce their intention to start recording a short time before capturing footage, effectively threatening the children to start behaving or else they're making the year-end YouTube bad boy compilation reel.

The idea is to handle the "low-level disruption" caused by troubled pupils, with the cameras constantly buffering an encrypted stream of the action in the classroom -- but only saving out a viewable chunk when a teacher hits the record button.
