The threat · Intruders approaching on foot, unseen?

D-Ground

Buried seismic sensors detect footsteps and digging on access routes and perimeters, with early warning before an intruder reaches the fence.

Hear the footsteps before the fence.

Long access routes, pipeline strips and open borders cannot be fenced everywhere, and a visible sensor is one an intruder can avoid or sabotage.

01

Early warning before the fence

Detects footsteps and digging as soon as someone enters the protected route.

02

Invisible, hard to defeat

Installed below ground: cannot be seen, sabotaged or bypassed.

03

Years without maintenance

Stand-alone on one battery for years, with automatic self-test.

D-Ground uses seismic sensors installed below ground. They recognize the fluctuations of an intruder's movement as soon as he enters the protected route, road or path, and warn before the intrusion actually happens. A self-learning algorithm recognizes diverse threats, from footsteps to digging, above and below ground, with minimized false alarms.

Buried and invisible, the system cannot be detected or bypassed and leaves the area's appearance unchanged. It runs stand-alone on the same battery for years, or integrates with video systems, alarm systems and smartphones.

From the first touch to the right response.

  1. Buried sensor line

    Seismic sensors are laid in a trench along the route or perimeter.

  2. Ground fluctuations

    Footsteps, digging and other activity create fluctuations near the sensors.

  3. Self-learning analysis

    The algorithm classifies the threat and calibrates itself to environmental noise.

  4. Alarm

    Thresholds per threat and time of day; alerts go to video systems, alarm systems or smartphones.
