DPP – Dual-technology System with detection of the crossing point
Analizzattore Interrato
HOW IT WORKS
Volume change in the generated electromagnetic field and pressure changes in the surface area caused by walking, running, jumping, driving etc.

LOCATION
In all surface areas and underneath sand, grass, pebbles, paving, asphalt etc.

LENGHT
From 20m to 200m (Stand Alone) / 12.8 Km (Multiplex). The detection strip is about 1.5 to 3.0 metres wide.

ALARM ZONES
A maximum of 2 zones (Stand Alone), 20 zones for 200m (Multiplex).

ADVANTAGES
Invisible, and combines the advantages of the active RPS and the passive GPS detection systems. DPS has the highest detection rate and the lowest FAR (False Alarm Rate).
PANORAMICA
DPP®, Dual-Technology Perimeter Position System, is a dual technology system created by the combination of invisible systems: PPS™, detecting the pressure difference with identification of the crossing point, and RFC™ detecting changes in an electromagnetic field. Through the use of a DSP microprocessor, this system allows processing a large number of signals received in a very short time. The change of pressure and electromagnetic field generate signals that, properly processed and analysed, allow the correct determination of system alarm conditions. The alarm signals obtained this way are then sent to the control centre. The system is modular and allows the protection of extended perimeters. It can generate the alarm event when the signal comes separately from the two technologies (OR), or only when the detection comes from both sensors (AND).

VERSIONS
DPP® is available as a Stand-Alone version, for maximum protection of 200 mt, and in Multiplex version, for maximum protection of 12.8 Km, with a single perimeter control unit (MIND™). The architecture allows interconnection of up to 64 MIND™ units.

OPERATIONS
DPP® is based on two technologies, and it uses their main characteristics according to the type of installation: PPS™ and RFC™.
PPS™ detects the pressure differences created by people or objects on the ground, passing over the sensitive area. RFC™ detects the changes in the electromagnetic field generated by people or objects crossing the sensitive area; it then makes a comparison between the radiofrequency energy that is transmitted and received. The signals obtained from the two sensors are sent to the analyser, which analyzes and transmits warning or alarm signals to the control unit.

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. This system identifies the crossing point.

The possibility to calibrate the sensitivity of each leg allows the system to adapt to the particular characteristics required for each installation.

CHARACTERISTICS
- Signal processing in the time domain.
- Signal processing in the frequency domain.
- Combined frequency-time processing.
- Use of masks to characterize and recognize signals sent by sensors.
- Detection of signal energy levels (spectrum analysis).
- Listing per category of signal energy matrixes.
- 8 local inputs and 8 relay outputs available (optional).
- Local recording, selfcalibration.
