Green palisade fence topped with taut wires along the outer perimeter of a military camp in deep snow

Cut, climb or spread: the wire reports it.

D-Taut Wire combines tensioned wire with D-FENCE strain-gauge sensor posts. It is a physical barrier and an electronic detection line in one, installed around airports, prisons, borders, nuclear plants and other high-sensitivity sites.

Pinpoints the attempt

Each sensor zone reports on its own, so the control room sees exactly where the wire was cut, climbed or spread.

Upgrades what you have

Mounts on palisade, welded mesh, chain link, concertina or walls, or stands alone as the fence.

Weather is not a trigger

A 15 kg deflection threshold ignores wind, plants and small animals; no pre-emptive maintenance is needed.

It mounts three ways: on top of an existing fence with outriggers against climbing, over the full height of a fence against cutting, or as the fence itself. The wires attach to the sensors on the posts, and any cut, climb or spread changes the tension and raises the alarm.

It runs on airport perimeter walls in South Korea, on military-camp perimeters in deep snow and along private garden walls.

From the first touch to the right response.

Tensioned wires
Regular, braided, barbed or aircraft wire is tensioned to the sensor posts.
Sensor posts
Strain-gauge sensors feel any cut, climb or spread; 15 kg and above triggers an alarm.
Zone controllers
Sensor controllers along the line report each zone of up to 100 m.
Gateway and API
RS485 to the D-FENCE gateway, then IP to cameras, client systems and the operator screen.
Response
The operator sees the exact zone, with the nearest camera on screen.
