AX PRO Internal Wireless Glass Break Detector, 8m Detection Range, configurable through App, replaceable battery with 5 year life span, 2 year warranty.

What it does

The AX PRO Wireless Glass Break Detector – 8m Range (SKU DS-PDBG8-EG2-WE) is an indoor sensor that reacts to a window breaking, so the alarm can sound before anyone climbs through. A door contact only notices a door opening, and a PIR (passive infrared motion sensor) only notices movement inside the room. Neither covers a smashed pane on its own.

Check these before you buy

• Range: 8m. Measure from the spot where you would mount it to the furthest window you want covered.
• Wireless. There is no cable to run back to the alarm, which helps in rooms where drilling through walls is awkward.
• Set-up through the app. Settings are adjusted from the AX PRO app rather than on the detector itself.
• Battery: replaceable, 5 year life span. When it runs down you change the battery, not the whole unit.
• Internal use. Mount it inside the building.
• System. It is an AX PRO device, so confirm your alarm is an AX PRO system.

Where it fits

Rooms with a large window, a glazed front door panel or a conservatory-style run of glass are the obvious candidates. Think of it as an extra layer alongside your door contacts and motion sensors, not a replacement for them.
