Best home security system: the best security kits for greater peace of mind

You can now feel safer with access sensors, motion sensors, cameras and more besides all monitoring the inside and outside of your home.

We’ve taken a look at some of the best home security systems available right now to see which ones are best for beginners, security experts, smart homes and more, rating them on what’s included as well as their ability to expand into larger set-ups down the road.

Samsung has been trying to take the lead in the home security market for some time, and it may have finally achieved supremacy with its impressive SmartThings system.

Not just a security investment, but a complete smart system for your home. The range boasts compatibility with a massive range of third-party products from leading brands like Sonos, Philips Hue and more. That means, alongside Amazon’s Ring (see below), it’s really the best option for those looking to expand to a future-proof smart home set-up over time.

The basic kit itself includes a hub, multi sensor, motion sensor and presence sensor, so you will need to purchase other products if you want video coverage, but you can set up routines and timers through the app. The SmartThings kit is also compatible with Amazon Alexa and Google Assistant so, if you already have a smart assistant you can get started building automations and voice commands straight away.

The keypad is easily mounted onto a convenient wall, and you can also control the alarm via the Ring app. Although it doesn’t come with a security camera included, you can hook the system up to other Ring products such as a Ring Video Doorbell, and it’s also simple to use with smart home systems such as Amazon’s Alexa.

This compatibility makes it super-easy to build out an wider-ranging system. If you already have some smart devices in your home and want to make better use of them, then Ring’s offering could be your best choice. Livingetc rating: 4.5 out of 5 stars

As said, there are a few different combinations you can try with the 13-piece set being the most comprehensive with a SimpliCam, glass break sensor, wireless siren, panic button and 2 key fobs also included.

With just two access sensors, a base station and a key fob, the Honeywell Home security system is a brilliant place for beginners to start their journey to a safer home.

The space-saving base unit acts as a motion detector that will record crisp 1080p HD video when it senses movement and, if you want video coverage outside, you can connect third-party sensors and cameras to the hub. And the Honeywell system isn’t just compatible with Alexa, it’s actually more of a security-focused Alexa device in and of itself, allowing you to access things like Amazon Music, weather information and audiobooks through the base station.

How do security systems work?

Building on the safety provided by the best security cameras, home security systems include tools such as motion sensors, smart locks and entry sensors that can detect when someone has entered the home – whether they have been invited or not. This makes it much harder for unwanted guests to enter without detection even if they are able to evade a security camera’s field of view.

The biggest role of security devices is no doubt their role as a deterrent as, if potential criminals are faced with a home that has cameras and motion sensors installed, they are less likely to attempt a break-in in the first place. And now that almost all security systems are connected to smartphones through an app, immediate alerts are now possible even if you’re not physically at home.

What are entry sensors? 

You may notice that many of the products listed here include something called an ‘entry sensor’ or ‘access sensor’. These are devices that come in two parts – one attached to a door or window and the other to the wall beside it.

These two parts are able to sense when they are close together or far apart so, if the window or door is opened without you knowing, an alert will be initiated. 

Which is the best home security system?

In our opinion, the best home security system available right now is the Samsung SmartThings starter kit.

While the system itself is somewhat basic in what it includes, we rated it highly due to its ability to connect to hundreds of third-party products, including those from Google and Amazon’s Alexa. 

Coming in second is the Ring Alarm Home Security System, a 5-piece set that covers almost everything you need and is easily boosted by devices such as a Ring Doorbell or security cam.
