Gallery with paintings behind a rope barrier: a hooded intruder reaches for the central painting, the floor zone in front of it turns red and ALARM sounds

Lift a painting and the alarm sounds.

D-Picture is an anti-theft detection system for art pieces such as pictures and paintings. A D-FENCE strain-gauge sensor behind the artwork reads its static force; when that force changes because the painting is dragged, moved or replaced, the sensor reports the event and activates the D-FENCE alarm and every integrated security system.

The alarm starts at the wall

Theft is reported when the painting moves, not when it leaves the building.

Nothing for visitors to see

No bars, no glass boxes: the protection is behind the frame.

No maintenance visits

A 'shoot and forget' sensor with a 10-year sensor warranty.

The sensor mounts on concrete, metal, wood or glass and can be completely invisible, so the display keeps its design. The default design carries pictures of up to 50 kg; heavier works are handled by changing the installation method.

D-Picture is made for galleries, treasuries, museums, offices and homes. In the D-FENCE museum scheme it works with D-Pressure Strip in the floor in front of the artwork: the floor warns as someone approaches, the picture sensor confirms the touch, and the control room gets the alarm, the camera and an SMS.

From the first touch to the right response.

Picture sensor
A strain-gauge sensor behind the frame reads the painting's static force.
Sensor controller
Picture sensors are wired (4 × 22 AWG) to a sensor controller that forms the alarm zone.
Zone alarm
Moving, lifting or replacing the painting triggers the zone output.
Floor warning
D-Pressure Strip in front of the artwork adds a warning on approach.
C&C room
Alarm, camera and SMS alert reach the control room and D-Command Control.
