Every alarm is the same 125dB unit. The only thing that changes is how much of your home you cover, and how much you save doing it.

Third alarm I've tried (but the first vibration based one) as the others kept going off randomly so I'd just given up. This one has adjustable sensitivity, set it once, three months later not a single false trigger. Sometimes the simple thing just works better. Sleep a lot easier knowing it's there.

Thought glass break sensors had me covered. They don't stop someone who doesn't break the glass. This little thing detects the vibration the second they touch the window. Wish I knew this sooner.

Cancelled my monitored alarm system after two years. Bought four of these, spent $80 total, and I feel more in control of my home security now than I ever did paying that monthly bill.

How it protects
Most alarms wait for broken glass. TremShield doesn't.
Unlike glass break sensors, TremShield detects vibration and triggers the moment someone touches your window with intent, before they ever get in.
- Ear-splitting 125dB. Zero false alarms.
- Peel, stick, done — no drilling, no tools, no landlord permission needed
- One-time purchase. No subscription. No app required.
They see it on the glass. They choose another house.
TremShield acts as a warning first, then blasts a painfully loud alarm the moment someone hits or forces the window. Homeowners finally sleep through the night, renters get protection they can take with them when they move, and everyone avoids apps, Wi-Fi issues, subscriptions, and constant false alarms thanks to the on-device sensitivity dial.

Also Works Beyond Your Windows
- Windows & Glass Doors
Detects the vibrations the moment someone tries to force open or break a window.

Mount it directly on any door panel or drawer front to catch knocks, forced entry attempts, or impacts.
- Metal Surfaces
Also works on lockers, filing cabinets, safes or even your fridge door to guard valuables wherever they are.
What changes after
“I live alone and my bedroom window faces the street. For the longest time I just couldn't sleep properly. Slept properly the first night I put it up. I don't know how to explain it but just knowing it's on the window changes something. You kinda forget it's there. But I know it's there.”
FAQ
The questions we get most
Mostly about how it compares to smart alarms and subscription systems.
Yes. 125dB is louder than a chainsaw and designed to wake you instantly, even through closed doors.
No. The built-in sensitivity dial lets you tune out everyday vibrations like traffic or wind, so it only triggers when someone actually strikes the glass.
Never. One payment, yours forever. No subscription, no contract, no company that can raise the price on you next year.
No. We built TremShield offline on purpose. No Wi-Fi, no app, no network means hackers have nothing to attack and nothing to shut down.
It runs entirely on batteries, so a power cut changes nothing. TremShield stays armed and ready whether the lights are on or not.
No, TremShield peels off cleanly without adhesive damage, making it safe for renters.
No, because of the order things happen in. TremShield reacts to vibration, not to the window opening, so the first contact with the glass sets it off. The 125dB siren is already sounding while they are still outside, and pulling the unit down afterwards does not take that back. That noise is usually the moment someone decides your home is not worth the risk.
Up to 12 months on a standard battery, and replacing it takes under 30 seconds with no tools required.
Most cheap window alarms fail in the same three places: a flimsy adhesive that falls off, a plastic housing that cracks, and a sensor that triggers at everything or nothing. TremShield fixes all three: 3M-grade adhesive that holds 12+ months, a single sealed housing with a slide-off cover, and a sensitivity dial you set yourself. You're also backed by a 30-day return window and support that replies within 24 hours.
Yes. A University of North Carolina study of 422 convicted burglars found 60% immediately choose a different target the moment they spot a visible alarm on a window.
