The technology is called “Sky Fence” and creates a 600m shield around a prison which will detect and deflect the remote-controlled devices.
It uses a series of ‘disruptors’ – sensors to jam the drone’s computer – and block its frequency and control protocols. The operator’s screen will go black and the drone will be bounced back to where it came from.
Drones have become a major security problem in Britain’s prisons and are increasingly used to smuggle in drugs, weapons, and phones.
The new system is being introduced at Les Nicolles Prison on Guernsey, where around 20 disruptors will be installed on the perimeter and inside.
