Early warning before the fence
Detects footsteps and digging as soon as someone enters the protected route.
The threat · Intruders approaching on foot, unseen?
Buried seismic sensors detect footsteps and digging on access routes and perimeters, with early warning before an intruder reaches 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.
Detects footsteps and digging as soon as someone enters the protected route.
Installed below ground: cannot be seen, sabotaged or bypassed.
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.
Seismic sensors are laid in a trench along the route or perimeter.
Footsteps, digging and other activity create fluctuations near the sensors.
The algorithm classifies the threat and calibrates itself to environmental noise.
Thresholds per threat and time of day; alerts go to video systems, alarm systems or smartphones.
Every image opens full size. Product sheets are shown whole, exactly as D-FENCE publishes them.
Copy it into your specification. It describes the system by what it must do, so any alternative has to meet every point.
The system shall be D-Ground by D-FENCE Electronic Fencing and Security Systems Ltd. (ISO 9001:2015 certified quality management), or an approved equivalent that meets every requirement in this section.
Buried seismic sensors detect footsteps and digging on access routes and perimeters, with early warning before an intruder reaches the fence.
Before installation, the contractor shall submit the manufacturer's datasheet, the installation instructions and the zone layout for approval.
Tell us the site, the threat and the line. D-FENCE engineers will propose the right barrier, sensor and platform, ready for your integrator.

Unauthorised vehicles on your access roads?
A pressure strip across the road that reports every unauthorised vehicle, fixed in place or deployed in minutes where you need it.

Open land too long to watch?
Standard field fencing with D-FENCE sensor posts: fast to deploy along long open perimeters, as a retrofit or stand-alone.

Equipment unbolted and stolen at remote sites?
A strain-gauge sensor built into the nut: any attempt to loosen, bend or cut the bolt raises an alarm with its location.
