SG-1 Seismic Detector

The SG-1 is an outdoor seismic detector, which can be integrated with existing security systems.

SG-1 seismic detector is installed underground and is able to recognize footsteps and vehicles.

SG-1 seismic detector is resistant to extreme environmental conditions, such as:

  • Weather & temperature changes
  • A large variety of terrains (no need for line of sight)
  • No interference by vegetation
  • Strong winds

SG-1 seismic detector cutting edge technology provides the ideal protection:

  • Reliability: A unique cutting edge algorithm, developed especially by SensoGuard. Automatically and continuously calibrated to environmental influences, keeping the false alarms rate at an absolute minimum.
  • Event Classification: The SG-1 algorithm classifies the threat and can be configured to different sensitivity levels for each threat.
  • Invisibility: The sensor installed underground cannot be detected by intruders, and does not change the area's appearance. This result in a system which can neither be bypassed nor sabotaged.
  • SG-1 seismic detector includes solid state relay outputs (N.O, N.C) which provide silent operation and longer operating life compared to electro-mechanical relays.
  • Low Power Consumption: The seismic detector consume only 3mW and can be operated by batteries for a very long period of time

How it works:

When an activity is registered in the protected area, the seismic sensor (Geophone) produces a signal which is processed in real time through the advanced algorithm, identifying which type of activity has been registered; walking, vehicle etc.

The SG-1 seismic detector has been developed according to the highest standards and is functioning in a completely reliable manner during several years, with minimum maintenance

Technical specifications:

  • Operating radius: Up to 12 m radius (depending on the area's terrain)
