The Sky Fence system will stop the devices travelling into and over the prison fence to prevent illegal items such as drugs, weapons and mobile phones from being dropped into the grounds.
While it is not known whether drones have been used to get items into Guernsey Prison previously, it has become a well-known problem for many UK prisons.
Last week, a man was charged in connection with using drones to smuggle cannabis, steroids and mobile phones into HMP Birmingham.
The new system forms part of Guernsey’s Home Affairs security upgrades – a £1.7m project that also includes new cameras, a new lighting system and new alarms.
Bill Millar, Jersey’s prison governor, said La Moye has not encountered problems with drones but they would monitor the success of the system in Guernsey.
Richard Gill, a drone expert who developed the system, said ‘disrupters’ will be used to create a 600-metre tall electronic barrier around the prison.
‘It will look like it is bouncing off a forcefield. The operator’s video screen will go black and they will lose control,’ he told The Times.
Prison governor David Matthews said Guernsey was leading the way in the world for prison technology.
‘This is the first time this technology has been used in any prison anywhere in the world.
‘Drones could carry weapons, contraband, mobile phones and drugs. This is about prevention,’ he said.
