Glass Break Alarm 2-Pack, 100 dB Vibration Sensor Alert, Adhesive Mount Installation, Battery Operated with Batteries Included, Window Door Security, No Wiring Required, Home Apartment Renter Safe

Ground-floor windows and glass doors are common entry points for burglars. These glass break alarms add an instant layer of protection—when glass shatters, the vibration sensor triggers a 100 dB alert that scares intruders and draws attention.

Who This Alarm Is Best For:

• Apartment and condo dwellers with vulnerable windows
• Homeowners with ground-floor or basement windows
• Renters wanting security without permanent modifications

Vibration Detection Reduces False Alarms

Unlike sound-activated alarms that can trigger from thunder or loud noises, vibration sensors detect the specific pattern of breaking glass. The sensor must be physically attached to the glass, so environmental sounds don’t cause false alerts. When the glass actually breaks, the 100 dB alarm activates instantly.

True DIY Installation

Peel the adhesive backing, press onto clean glass, and the alarm is active. No wiring, no drilling, no tools, no professional installation. The compact design (2.5″ x 0.75″) sits unobtrusively on any window or glass door. When you move, they remove cleanly without damaging property.
