Garden wall with its coping lifted: the ultra-slim D-Tech pressure-sensor strip runs along the wall top, next to a lawn with sun loungers

The wall top that reports every climb.

D-Tech is the next generation of the D-FENCE pressure sensor: an ultra-slim strip that is installed covertly on walls, fences or the ground. On a wall it sits under a metal or stone coping that is made to your height, width, length and colour. The moment an intruder puts his weight on the wall top, the alarm is raised.

Invisible protection

The sensor hides under the finish, so the wall, gate or floor keeps its look.

Alarms on real intruders

It measures weight on the barrier; the catalogue false-alarm rate is less than 1 per km per 3 months.

One sensor, many surfaces

Wall tops, gates, decks, steps and interiors run on the same strip and controller.

The same sensor goes where a fence cannot: under gate frames, and under decks, steps and floors, including the floor in front of a safe. Each strip is up to 6 m long and carries a cover of up to 350 kg; the alarm threshold is set about 15 kg above the static weight of the cover, so rain, wind and small animals stay below it.

D-Tech outputs a dry contact (N.O. / N.C.) and RS485 to the alarm panel, CCTV, siren, floodlight, mobile app or control room you already use, and into D-Command Control.

From the first touch to the right response.

Slim sensor
The D-Tech strip lies under the coping, gate frame or floor cover.
Weight on the cover
A climber adds load; about 15 kg above the cover weight triggers the alarm.
Controller
The processor sends a dry contact (N.O. / N.C.) or RS485 message.
Local response
CCTV, siren and floodlight are triggered on site.
Notification
The mobile app, the security control room and D-Command Control receive the event.
