Windows are one of the easiest entry points in any home or office, and most people don't give them a second thought until something happens. These glass break alarms detect vibration the moment a window is struck, hit, or broken — then blast a 100dB siren that scares off intruders and alerts everyone nearby.

  • 100dB siren triggers when glass is hit, knocked, or broken
  • Peel-and-stick adhesive installation — no tools or wiring needed
  • Siren sounds for 30 seconds then automatically resets
  • Two units included for double the coverage
  • Battery powered with LR44 button cells included

Windows Are Entry Points — Treat Them That Way

In the real world, a ground-floor window is one of the most common ways someone gets into a home uninvited. All it takes is a rock, an elbow, or a pry bar. Most homeowners lock their doors but leave their windows as afterthoughts. These glass break alarms change that equation for less than the cost of a pizza.

When the vibration sensor picks up an impact on the glass, the 100dB siren kicks in immediately. That’s loud enough to startle an intruder, alert your household, and draw attention from anyone within earshot.

Who This Alarm Is For

Homeowners with ground-floor windows, especially those facing alleys, backyards, or less visible areas, get the most benefit here. If you’ve got basement windows or sliding glass doors, these sensors add a layer of protection that doesn’t require running wires or paying for a security system.

Renters and apartment dwellers can install these without landlord permission since there’s no drilling or permanent modification. Office managers and small business owners use them on storefront glass and back windows where break-ins are most likely.

Is This the Right Choice for You?

Choose this Glass Break Alarm if you want:

  • Affordable window security with zero installation hassle
  • Immediate 100dB alert when glass is impacted or broken
  • Two-pack coverage for multiple windows at a low cost

Consider something else if you need:

  • Alerts sent to your phone or a monitoring service
  • Protection for non-glass entry points like doors

Set It and Forget It — Until You Need It

Installation takes about thirty seconds per unit. Peel off the adhesive backing, stick it to the window, and flip the switch to arm it. That’s the whole process. No wiring, no apps, no monthly fees. The vibration sensor detects any significant impact on the glass — whether someone smacks it, tries to pry it, or breaks through it entirely.

When triggered, the 100dB siren runs for approximately 30 seconds, then shuts off and automatically resets. That auto-reset means you don’t have to manually disarm and re-arm it after each activation. The included LR44 button cell batteries keep it running, and the compact 2.5″ x 0.75″ design means the alarm sits unobtrusively on the corner of any window.

Frequently Asked Questions

Will this alarm go off from normal vibrations like wind or a ball hitting the window?

The sensor is calibrated to respond to significant impacts — the kind that come from someone trying to break or force the glass. Normal household vibrations, wind, and light bumps generally won’t trigger it. A hard knock or forceful strike will.

How long do the batteries last?

The LR44 button cell batteries last for months under normal standby use. Since the alarm only draws power when actively sounding, battery life is primarily affected by how long the unit is armed, not by frequent activations. Replacement batteries are inexpensive and widely available.

Can I use these on sliding glass doors?

Yes. The vibration sensor works on any glass surface, including sliding glass doors, picture windows, and sidelights. Just attach the alarm directly to the glass panel where an intruder would most likely make contact. One alarm per glass panel is the recommended setup.
