The centre of the system is the patented FU electronic outrigger. The electronics are integrated into the fencepost to make it vandal resistant, and to be able to monitor a 2.5-m high fence. This means that attempts to climb the fence can be located exactly and the CCTV system activated accordingly.
The sensitivity of the system, i.e. the thresholds at which the electronic outrigger activate the alarm, is set in the central control unit and can be varied for different sections of the project. Therefore, false alarms caused by wind, snow, hail or ground movement can be completely eliminated.
