If the thought of getting a home security system raises alarm bells — How much do these things cost? Is there a yearly fee? Do I have to get in a professional to install it? Is it hard to use? — let us put your mind at rest by telling you that the best home alarm systems nowadays are surprisingly economical and user-friendly, a breeze to set up all by yourself, and come with no contract or fees.
From as little as £40, you can start deterring intruders, monitoring your property, and protecting your home and family.
How do I choose a home alarm system?
There are three main types of home alarm systems to choose from.
Contact sensors attach to windows or doors and alert you if these have been opened, either by way of a loud siren, or a notification on your smart device.
Motion sensors can sense any movement in their field of “vision” and again, depending on how you’ve set them up, either alert you via siren or a smart notification.
Camera security enables you to see any action happening either inside or outside of the house via an app on your smart device, and you also have the option to record and playback video footage, too.
Home alarm systems come in many forms and can be a mix and match of the above main types, i.e. the Ring Alarm 10-piece home security kit includes three motion sensors, and four-door and window alarms, and you can also sync it with home security cameras (or smart doorbell cameras) to get the fully-comp home security experience.
Whether you want a simple intruder siren at the front door with an on-off switch, or if you want to be able to monitor every door and window in your house, as well as any movement both inside and outside via a smartphone or tablet, you’ll be able to find something for you on our list of the best home alarm systems below.
