Glass Break Detectors — Specs, Brands & Hong Kong Installation
Acoustic detectors that listen for breaking glass across a room — useful for shopfronts and glazed offices.
What this sensor does
Glass-break detectors cover several windows from one device by analysing the flex and shatter frequencies of breaking glass. They suit rooms where putting a contact on every pane is impractical — meeting rooms, living rooms with full-height windows, and street-level retail glass.
Honeywell 5853 is the wireless 5800 option for finished interiors. Bosch DS1101i is the wired acoustic detector we use on G-series commercial jobs.
- 7.5 m class detection radius
- Dual-frequency flex / shatter analysis
- Walk-test LED for commissioning
- Wired and wireless options

Hong Kong / local context
Street-level glass with heavy traffic can confuse cheap vibration sensors. Acoustic glass-break is usually cleaner on Nathan Road / Causeway Bay shopfronts.
The detector needs line of sight to the glass — do not hide it behind signage or dense displays.
Other sensor types
Complete coverage usually mixes several detector types on one panel.
PIR Motion Sensors
Passive infrared and dual-technology motion detectors for rooms, corridors, and shop floors.
