Home Alarms

A home alarm is a small, battery-powered device that sounds a loud alert the moment a door or window opens. No wiring, no monthly fees, and no contract. These are not hardwired, so renters and dorm students can use them without breaking a lease or losing a deposit, and you can pull them off and take them with you. Toss them in a bag for a hotel or your next place, and set up protection anywhere in minutes.

Find the Right Home Alarm for Your Space

Apartments and dorms: The 90dB Magnetic Door and Window Alarm 2-Pack peels and sticks in seconds with no tools and no damage to the door. Good for renters who cannot drill or modify anything.

Entry doors: The Door Stop Alarm wedges against the door and sounds when pressure hits it, which adds a physical barrier on top of the noise. Works for front doors, bedroom doors, and travel.

Windows and glass: The Glass Break Alarm 100dB 2-Pack alerts you the instant a window is struck or shattered, covering the access points a door sensor cannot.

Why These Alarms Work

The best home protection is the kind you actually set up and use. These alarms need no subscription, no app, and no electrician. They run on batteries, sound on their own, and keep working even if your power or internet goes down. Pair a few across your doors and windows and you have full coverage for less than the cost of one month of a monitored service.

Home Alarms Questions

Do these home alarms require professional installation?

No. Every alarm here is designed for you to set up yourself in minutes. Most use peel and stick or magnetic mounting with no tools, no wiring, and no drilling, which makes them a good fit for renters and homeowners alike.

Is there a monthly fee or subscription?

No. These are standalone battery alarms with no monthly fee, no app, and no contract. You buy the unit once and it works on its own, with no service to sign up for.

How many alarms do I need for my home?

Cover each ground floor door and any reachable windows. Count your exterior doors, sliding doors, and ground floor windows, and plan one alarm for each. Multi-packs cover most homes and cost less per unit.

Will these alarms work if the power goes out?

Yes. Because they run on batteries and do not depend on wifi or your electrical system, they keep working during a power outage or internet outage, which is often when you want them most.
