GPS Plus PRESSURE DIFFERENCE-BASED system
GPS Plus, Ground Perimeter System, is the ideal solution for sites
at high risk of intrusion.
GPS Plus is designed with DSP microprocessor technology (Digital
Signal Processing). The signal from the sensor is digitized and
analysed in time and frequency domains, providing extremely
accurate processing.
In addition to high immunity to weather related interference, typical
of the underground tube system, the sensor can also identify signals
to be ignored, such as those with a repetitive frequency (rail, road

PPS System with DETECTION of the crossing POINT
PPS, Perimeter Position System, represents the evolution of the
traditional GPS Plus system. This is also based on pressure
difference detection. The innovative feature of PPS system is the
ability to determine the crossing point of the protected strip with
a maximum resolution of ± 5 mt, giving detection of a maximum of
20 crossing zones, distributed over 200 mt of protection, obtained
with a pair of sensors. The length and number of zones can be
configured using the management software. The pair of GPS sensors are at the heart of

The system is passive and, therefore, not detectable.
Operation. PPS is based on the detection of a difference in pressure between two tubes laid
down and buried along the perimeter to be protected, then filled with a liquid that allows operation
even at low temperatures (antifreeze) and properly pressurized. Crossing the sensitive strip generates a
pressure difference between the tubes; this is detected by a special transducer and the signal thus
obtained is analysed; any alarm condition is sent to the control centre. At the same time, the DSP
analyser processes the signals coming from the two sensors located at the ends of the sensitive area, and
defines the exact crossing point. Furthermore, the system can store signals generated before and after
the event and then review them later. The ability to calibrate the sensitivity of each section independently
allows the system to be adapted to the particular characteristics of each individual installation.
PPS intelligent components are self-protected by a "watch dog" system; in case of shutdown, this will
automatically restore normal operation. This system can be combined with other protection systems
(perimeter, indoor sensors, CCTV, access control, fire systems) and it can be centralized with flexible
solutions for any requirement and application.

DPS Dual-technology System
DPS, Dual-Technology Perimeter System, is a dual-technology system
created by the combination of two invisible systems: “GPS PLUS”,
detecting pressure difference, and ”RFC” detecting changes in an
electromagnetic field. Using a DSP microprocessor, DPS allows the
processing of a large number of signals received in a very short time.
The changes in pressure and electromagnetic field generate signals
that, properly processed and analysed, allow the correct
determination of system alarm conditions. The alarm signals

MILES FIBRE OPTIC FOR PIPELINE System
MILES is a protection system for ducts and pipelines.
It uses a fibre optic cable and has a very high detection capability,
being totally immune to electromagnetic interference and
atmospheric conditions.
The fibre optic cable requires no power in the field and, therefore,
power supply units along the protected perimeter protected are not
required.
The system allows the protection of very long pipelines (gas, oil
pipelines, etc.), up to 50 km, and the area where the sabotage is
taking is identified to the nearest few hundred meters. Fibre optic is The fibre optic is the sensitive part of the
MILES system, as it is particularly sensitive to

Operation. The fibre optic cable is subjected to mechanical
stress caused by stimuli, such as pressure, vibration and motion,
which changes the transmission characteristics of the light inside
the fibre. The change is minimal, but with a source of coherent light
obtained with laser diodes and sophisticated amplifier and processing
systems, a signal that can be processed can be obtained.
The careful analysis of the signal and the ability to change, using a
calibration and monitoring software, specific parameters that
determine the system operation, give this product excellent
performance characteristics.

System configuration.
Components. The system is divided into 2 main parts:
fibre optic in the field and PC-based signal analyser in a control
room. The fibre optic is the system “sensor” and it is sensitive to
mechanical stress produced during attempted sabotage (digging the
ground, explosion, hammering, etc.).
The analyser processes the signals generated by the differences
between the transmitted and received light beams using
sophisticated software algorithms. It consists of the laser light Characteristics.
