The following diagram shows how these sensors are buried in a typical installation. Signal and power
to the sensor is supplied from a buried Ethernet wire which goes to the server at the security
command and control console.
A hole is dug approximately 18 inches by 18 inches (45cm x 45cm) by about eighteen inches (45 cm)
deep. A four inch (10 cm) layer of sand is placed in the hole and the sensor is placed on top of the
sand. The sensor is then covered with sand about one inch 2.5 cm) deep. Earth (topsoil) is then used
to fill the hole completely or if the sensor is under pavement then asphalt or concrete is used to fill
the hole to the existing grade. Note that highly conductive soils such as wet clay covering the sensor
can reduce the detection range.
The sensor can be wall mounted
as shown.
The resulting side view of the installation
complete with detection field is shown
(right).The detection hemisphere has a
diameter of 50 feet (15m).
