From simple to high-tech mega alarms, we at Home Security Store stock a great selection of door alarms to give you endless options of how to keep your entrances and exits safe.

Keep in mind that front and back doors are not the only entrances to your home or business. Windows, garage doors, basement doors- they all allow access to unwanted company, but there are simple ways to protect those often ignored areas with our products. If you settle for the first alarm you see, you’re doing yourself an injustice.


What alarm is right for you? Things to think about when searching are:

What am I using it for? If you’re afraid of a burglary at night, take a look at our ear-piercing break sensor alarms that will either wake you up in time to stop a burglar or scare them away because of the noise and attention it draws to them.

If a burglar is vicious, what’s stopping them from breaking my door down? Try our Guard Dog- a door blocker with a Loud alarm should the blocker be defeated- covers you on two levels of security.

We at Home Security Store believe in doing research. Knowing your home or business and the alarm that you use for it is priceless. Search for the door alarm or alarms that are right for you, and we’re sure that you’ll find what you’re looking for in our Home Security Store.
