Ajax GlassProtect - Wireless Acoustic Glass Break Detector - Black

Fine-Tuned Acoustic Surveillance for Structural Glass Surfaces

The Ajax GlassProtect Jeweller in black finish is an ultracompact wireless security sensor engineered to merge high-performance perimetric tracking with full visual concealment. It is ideal for modern architectural spaces featuring dark-painted window profiles, tinted aluminum frames, or sombre interior layouts. Armed with an advanced miniature electret microphone, this hardware device continually tracks ambient room frequencies. Upon mechanical impact followed by structural glass shattering, the local processor parses the sound signature in milliseconds, routing an instant intrusion alert to the master controller Hub in 0.15 seconds.

Two-Step Frequency Algorithm and Environmental Noise Suppression

The operational tracking logic of GlassProtect runs on precise digital signal analysis matching a proprietary dual-frequency verification script. To validate and trip an active alarm event, the onboard microphone module must detect inside an exact sequential window a low-frequency wave (the dull mechanical thud of an object striking the glass pane) followed instantly by a high-frequency wave (the distinct sharp crackle of glass pieces breaking apart and falling). This deep evaluation framework ensures ironclad protection against background noises stemming from lightning storms, heavy truck traffic, dog barking, or household item drops.

Hardwired Expansion Borne and Cryptographic Radio Infrastructure

On the back frame of the enclosure shell, the detector hosts a dedicated built-in wired input terminal supporting normally closed (NC) dry contacts. This integration tool enables field engineers to wire a secondary third-party peripheral — like a heavy rolling-shutter microswitch —, digitalizing telemetry loops through GlassProtect's radio link. Data transmissions rely on the proprietary two-way Jeweller network, featuring automated frequency hopping against active RF jamming and robust encryption to secure up to 1,000 meters of open line-of-sight range.
