Living room with a full-height glass facade onto a bamboo courtyard; the floor boards along the glass are lifted to show D-FENCE pressure sensors beneath

Nobody crosses this floor unannounced.

D-Floor places D-FENCE pressure sensors on rails beneath the floor finish: tile, stone, wooden or stainless-steel flooring. There is no limit on the size of the protected area. When an intruder walks onto it, the change in pressure raises an alarm; animals under about 25 kg do not.

Catch the intruder inside the line

The floor itself reports him, after the wall and before the door.

Nothing to see, nothing to avoid

The zone is hidden, so an intruder cannot step around it.

Pets and weather stay quiet

The weight threshold ignores animals under about 25 kg.

The same system is called D-Deck when it protects decking, passages, terraces and hallways, and D-Step when it is built into steps and stair treads. It can be installed permanently or temporarily, under metallic, wooden or plastic surfaces, and keeps an invisible look. The SECURITY Book lists D-Deck and D-Step for museums, high-rise buildings, offshore platforms and ships.

Typical zones are entrances and thresholds, pool decks, the floor in front of a safe or at the entrance to a classified room, and prison-cell floors. The alarm is sent to the D-FENCE control centre and to the cameras, sirens and phone apps you connect.

From the first touch to the right response.

Floor sensors
Pressure sensors on rails sit under the tiles, boards or plates.
A step on the zone
A person's weight changes the load; animals under about 25 kg stay below the threshold.
Controller
The alarm leaves as a dry contact or RS232 / RS485 message.
Control centre
The D-FENCE control centre, cameras and phone apps receive the event.
