GeoAcoustic Intrusion Detection Systems

Geoacoustic monitoring and detection systems for wide area land and marine surveillance. Used to protect ranches, pipelines, refineries, vehicle storage lots, mines, high value crops, and other large valuable facilities.  Using high resolution geophysical and acoustic methods, with state of the art PVDF, polymer, piezoplastic, ceramic, and moving coil electrodynamic transducers and sensors, combined with artificial intelligence data processing, results in end to end solutions for wide area detection, classification, monitoring, and general surveillance. Used by major petroleum companies such as Shell, vehicle fleet operators such as Pearce Coaches (the one in Australia, not Pearce, Arizona, USA), and mining companies such as Mitsui.



Do you have a large land area you want to protect?  Cattle, sheep, horses, and other valuable livestock that you don't want 'driving off' your station ?  Perhaps your property contains a mine site to whom trespassers would be a hazard to themselves and the mine? Large car, bus, and other vehicle storage lots where intruders are unwelcome? Fuel depots, pipelines, and other fossil fuel infrastructure where unwanted 'guests' can be disruptive?

Consider purchasing a GeoAcoustic Intrusion Detection/ Identification Wide Area Surveillance System from Marschall Acoustics Instruments.

Defend and secure your infrastructure assets with Marschall Acoustics Instruments    high resolution geophysical, acoustic, thermal, and optical surveillance and monitoring systems.


Vehicle usage of all types - automobiles, trucks, ATV's, aircraft, as well as a variety of activities - hunting, digging, and even just walking, set up vibrational waves and patterns in the ground as they take place on or near your property.

Marschall Acoustics Instruments ' geoacoustic sensor arrays and matching signal processing systems can pick up these vibrational elastic waves and distinguish their source's type, location, speed, heading, and very often their particular activity.

Depending on the specifics of the location, and the intruder types of particular concern, one or more sensor arrays consisting of normal stress sensors and/or particle velocity component sensors may be installed at a site.  Signal processing, monitoring, and recording can be as simple or as sophisticated as you want it to be.  From economical systems requiring a "man in the loop" to very long range fully automated systems with significant artificial intelligence and performance equivalent to their military counterparts.
