The sensor cable is deployed as an intrusion detection barrier along a site perimeter The sensor cable can also be buried covertly in

•

Gravel

•

Sand

• •

Sod Other factory approved media Common barriers:

•

chain link fences, ornamental fences,

•

anti-climb fences, walls, rooftops, walls

•

ceilings.

The APU can be located up to 20 Km from sensor cable

19



Unique fibre optic system for noise detection along the fibre.



Consist from two elements – optical fibre and the reading unit.



An acoustic signal is recorded for each metre along the fibre.



The system can detect the position of an event



Can distinguish separate events more than two metres apart .
