Seismic sensor MARTEC TEKELEC SYSTEMES

MYGALE Seismic detector

Border areas and a large number of sensitive sites now need totally discrete or buried, reliable and inexpensive detection equipment. Martec Serpe-Iesm has extended its range of intrusion detectors with its new multi-terminal sensor MYGALE.

Based on ground vibration detection techniques, this sensor, comprised of four seismic detection units comprising geophones and a local acquisition unit, allows optimum adaptation to the layout of the installation site.

The seismic units are connected to the acquisition unit by cables. Two additional inputs for dry contacts are also provided. The technologies employed by Martec Serpe-Iesm reduce environmental disturbances to a minimum and guarantee, for each seismic unit, the best detection performance possible within a radius of 10 to 30 metres depending on the type of land.

The seismic detection units can be deployed on different types of ground (soil, concrete, asphalt, etc.), spread out over an area or in a line along the outer perimeter to be protected. The ground vibrations created by an individual attempting to cross the protected space are transmitted to the local acquisition unit. This unit carries out the necessary processing operations to analyse the measurements and set off the alarm.

The sensor network enables linear deployment over a distance of 5,000 metres, of a system of detection which combines efficiency, stealth, and localisation of the alarm.
