Electric razor wire is more protective than the razor wire, it is designed to provide an intruder detection signal and if required can also provide a 7000 volt repulse shock.
Because the coil comes with a built in condutor, it provides for a low cost alarm system.
The coil is simply attached to a fence, wall or roof. An energiser is connected and the user has a physical barrier, detection and electric repulse system.
Innocent access to the live wire is prevented by the outer coil of barbed tape concertina.
As the inner coil is attached to the outer coil, the two coils move together in windy conditions etc. Thus avoiding false alarms.
