• Audible warning
• Additional peace of mind

Written by Alex Boyd Updated: 27 August 2024

Out of sight is out of mind, and that could be true of your garage. Garages will often contain many valuable items, such as cars, bikes and tools. These things are not cheap, so it makes sense to keep them as secure as you can, and a garage alarm could be just the protection you need.

A garage alarm system needn’t cost a fortune, and it could help to deter potential burglars and alert you in the case of any break-in attempts. Today’s alarm systems are more advanced than ever before and come equipped with motion sensors, door sensors, and cameras that can provide real-time monitoring and send alerts to your phone or other connected virtual assistants like Alexa. They provide a valuable added layer of security to your home as thieves are more likely to target homes that appear vulnerable or lacking in security features.

So, what do you need to protect your garage and its valuable contents? Here are some reasonably easy-to-install solutions to beef up your garage security.

FAQs

What to look for when choosing a garage alarm:

If you are going to fit an alarm to your garage, there are a number of things you may want to consider before making your choice.

Type of alarm: Would you prefer a wired or wireless system? Wired alarms require the installation of wiring and sensors, while wireless alarms can be installed more easily and can be monitored remotely.

Sensors: What type of sensors are appropriate for your garage? For example, motion sensors will detect movement inside the garage, while door sensors will detect when a door is opened.

Sound: Consider the loudness of the alarm’s siren. You want an alarm that is loud enough to deter would-be intruders and be heard from inside your home.

Price: Consider your budget when choosing an alarm for your garage. Prices can range from just a few pounds to hundreds of pounds depending on the features and capabilities

Compatibility: If you have a smart home system or other security devices, consider choosing an alarm that is compatible with your existing system.
