Passive ground detection
Buried detektion systems
The main feature of these types of systems is that they are invisible when installed and are therefore very difficult for an intruder to locate.
They follow the shape and contours of irregular interfaces and does not require 'clear view' of the application. This makes them ideal for irregular högsäkerhetsinstallationer.
They also do not need any special physical barrier fence or a wall.
It is essential that they work under different land surfaces such as grass, gravel, asphalt and laid flat surfaces, with the same zone.
GPS uses sensitive land hose that is parallel buried 25 to 30 cm deep and 1 to 1.5 meters apart.
They are filled with green liquid and pressurized to about 4 atm. The analyzer detects the pressure difference between the two tubes that are created by an approaching intruder.
