Ajax: GlassProtect
Manufacturer and Model
The "Acoustic Detectors" section presents the Ajax GlassProtect — a wireless glass-break detector with a microphone — from a company founded in 2011 in Kyiv by Aleksandr Konotopskyi, which over more than a decade has become Europe's largest security-system manufacturer, protecting more than 4.5 million people across over 180 countries.
A Gap Opening Detectors Can't Close
Unlike a contact opening detector, which registers a window actually being opened, GlassProtect detects the intrusion attempt itself through broken glass — the scenario where an intruder breaks the pane but doesn't open the window frame, leaving a contact detector untriggered. This is a fundamentally different protection level, closing a gap ordinary opening detectors can't cover.
How Acoustic Recognition Works
GlassProtect's operating principle is based on sound-spectrum analysis: a built-in microphone continuously "listens" to sounds in the room, and the detector's microprocessor compares the captured sound profile against the characteristic acoustic "signature" of breaking glass, distinguishing it from similarly loud sounds — dropped objects, slamming doors, or other household noises that could trigger false alarms in simpler acoustic detectors lacking such a recognition algorithm.
The detector's detection range is designed for a standard room or office space, so when planning placement, base it on the room's actual area and the number of window openings a single device needs to cover.
Technical Advantages and Choosing
GlassProtect runs on Ajax's own Jeweller protocol, providing stable radio communication with the system's hub and energy efficiency sufficient for years of operation on a single battery without frequent replacement.
Sensitivity and other parameters are configured remotely through the proprietary Ajax mobile app — the owner or installer doesn't need to physically remove the device from the wall or ceiling to change its configuration, significantly simplifying system setup at a site.
A compact housing and affordable price make GlassProtect an accessible solution for a wide range of sites — from a private apartment to an office or small shop, where installing a full video surveillance system isn't economically justified but window intrusion control is still needed.
Ajax systems built on these detectors became the world's first wireless security system certified to the European EN 50131 standard's highest tier, Grade 3 — a certification confirming resilience against jamming or breach attempts by intruders.
The detector's placement in a room affects recognition quality: it's recommended to install GlassProtect with a direct line of sight to the monitored windows, free of obstacles like curtains, furniture, or partitions that can muffle the sound of breaking glass and reduce trigger reliability.
The detector reports its own battery charge level to the hub, so the owner receives advance notification of the need to replace the power cell in the mobile app, rather than discovering the device has failed only after an actual intrusion attempt.
An acoustic glass-break detector works most effectively in combination with a motion detector or a contact opening detector on the same window: cross-checking signals from different detector types reduces false-alarm probability and gives the hub a fuller picture of the event.
Choosing specifically within the "Acoustic Detectors" section means comparing Ajax's products against other security-system manufacturers featured here on practical criteria: the accuracy of the glass-break recognition algorithm, detection range, and compatibility with an existing security-system hub.
We'll Help You Calculate the Right Number of Detectors
