Best Alarm Systems for Your Garage

We worry about keeping our windows and doors locked, but what we usually forget is that the garage can also be a gateway for thieves. If you keep your valuables in your garage and it is attached to your home, you should opt for a high-quality garage alarm that can keep the robbers and intruders out of your home. In this article, we have put together a buying guide that will not only provide you with important information on alarm systems for the garage but also help make your buying decision easier. Let’s get started.

How to Choose the Right Alarm System According To Your Needs?

Before buying an alarm for your garage, you should consider how you are going to use it. Just because an alarm system looks cool to you doesn’t mean it will actually provide you with the security you want. The most common types of garage alarms used are bell only, dialer alarms, wireless alarms, smart home security systems, and connected ones that you can integrate with your other home security measures such as security cameras.

The other thing you should consider is choosing between a wired or wireless alarm. Wireless alarm systems for garage use battery-powered sensors and are easy to install without professional help, and you can even get additional sensors with some alarms for increased protection. On the other hand, wired alarm systems need wiring running to each sensor and professional help to install them properly.

Types of Garage Alarms

1. Door And Gate Monitors

These alarms have a sensor that tells if your garage door is opened or closed. If it is opened, it alerts you and gives you an option to close it with the push of a button.

2. Motion-Activated Security Cameras

As the name suggests, this type of alarm has a little camera placed outside that typically has a long reach. If the camera sees any motion, it will alert you, and you can view the footage to check what set it off.

3. Motion Sensors/Detectors

Unlike a camera placed outside, these alarms are equipped with motion sensors that detect any motion and notifies you via a siren or a beeping sound.

4. Vibration-Triggered Alarms

Vibration-triggered alarms are very straightforward, and they go off when the window or gate is being shaken. One shouldn’t solely rely on this type of alarm for the garage because even strong wind can set the alarm off.

Here are some best garage alarms that you can opt for:
