DPS – Dual-technology System
Analizzatore Interrato
Volume change in the generated electromagnetic field and pressure changes in the surface area caused by walking, running, jumping, driving etc.

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

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

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

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).
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 obtained this way are then sent to the control centre.
The system is modular and allows 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).

DPS® 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.

DPS® is based on two different technologies: GPS® Plus and RFC™, enhancing their main characteristics. GPS® Plus is based on the detection of the difference in pressure generated by people or objects on the ground, passing over the sensitive area. RFC™ detects 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 two sensors are sent to the analyser, that analyzes and transmits warning or alarm signals to the control unit. Crossing of the sensitive strip generates a significant change of pressure in the tubes, which is detected by an appropriate transducer. It also generates a change of the electromagnetic field, which is detected by the RCF™ system Mixer.

The signals thus obtained are analysed by the DSP and translated into warning or alarm signals. The possibility to calibrate the sensitivity of each leg allows the system to adapt to the particular characteristics required for each installation.
