Hillside villa terrace with an infinity pool; a frameless glass balustrade with a slim metal capping runs along the edge above the valley and city

Keep the view. Stop the climb.

D-Glass brings intrusion detection to glass fences, balustrades and walls. D-FENCE strain-gauge sensors are either built into the sensor posts that hold the glass panels, or integrated into a metal capping on top of the glass. The result is an electronic perimeter that looks like an ordinary balustrade.

Security you cannot see

The detection is inside the capping or posts; the glass stays clear.

Alarms on climbers, not on guests

A climber's weight alarms; a hand on the rail does not.

Designed with the architect

Capping material and profile are chosen to match the building.

When someone climbs over the balustrade, the sensors feel his weight and raise an alarm; the newest D-FENCE decks add an alarm when the glass panels are broken. Touching or leaning on the capping does not trigger it. The capping comes in stainless steel, aluminium alloy or a metal coating, with an exterior designed to match the building.

D-Glass protects terraces, balconies and pool edges of homes and hotels, and glass partitions in museums and galleries. The alarm goes to the alarm panel, cameras, siren and floodlights, a phone app or the control room.

From the first touch to the right response.

Glass sensor
Strain-gauge sensors in the capping or in the posts between the panels.
Climb or break
Weight on the capping or force on a panel changes the load the sensor reads.
Controller
The alarm leaves as a dry contact or RS232 / RS485 message.
Local trigger
Cameras, siren and floodlight react on site.
Notification
The phone app, the control room and D-Command Control receive the event.
