Geophone seismic intrusion detection systems offer a reliable and cost-effective solution. Sensor lines follow the terrain with no need for line of sight. Where heavy landscaping, hilly terrain, and inconsistent perimeter shapes make other systems costly and impractical, seismic sensors performs properly.

The basic components of the seismic system are the geophone sensors and the seismic signal processor.

Geophones are placed in or on earth, asphalt or concrete to detect low-level intruder vibrations. These signals are processed and analyzed to selectively discriminate between actual intruders and natural disturbances.

GLS20 is a wired network of seismic sensors. The signal generated by each geophone is analyzed by the on board circuit which performs an analog and digital signal processing. Subsequently, the results of the signal processing is passed to the main controller which performs a further signal processing and decides if the alarm is a legitimate one of a false alarm. The legitimate alarm and the exact intrusion (accuracy of 10 m) are transmitted to the Control Room. This novel concept greatly improves the detection , lower the false alarm rate and enable the operator to point , manually or automatically, any camera to the intrusion section.

Each processor may be easily interconnected to standard security monitoring systems via normally closed or open alarm relay contacts. Security System Integration  Software (SSIS).
