Kilometres of open field, no early warning?

Farms, reservoirs, railways and pipelines run through open country, often with no fence at all or only a simple wire one. Crossing it is easy, and nobody is told.

Fast over long distances

Built on standard field fencing; no special skills or tools needed.

Retrofit or stand-alone

Add it to an existing fence or wall, or build a new line where there is none.

No high voltage

Electronic detection instead of a shock fence: no 10,000 V, no radiation.

The D-Field Fence builds on well-known, cost-effective field-type fencing. D-FENCE sensor posts are set into the fence line at any height the site needs, without special skills or tools, and a climb or cut on the wire raises an alarm with its location.

Fit it to an existing fence or wall, or put up a stand-alone line where there is no fence. It belongs to D-FENCE's Green Security Revolution family: electronic detection instead of a high-voltage shock fence.

From the first touch to the right response.

Sensor posts in the line
D-FENCE sensor posts carry the field-fence wire at the height you need.
Force on the wire
A climb or a cut adds load; typically 15 kg above the static load triggers the alarm.
Processing unit
Up to 24 sensors per unit, in zones of up to 90 m.
Alarm out
Dry contact or RS232 / RS485 to your alarm system, cameras or D-Command Control.
