Are home security systems worth the investment?

Research has shown that home security systems – whether that's a video doorbell, a single camera, or a comprehensive security system – actively deter criminals . So, yes, we would say that they're worth the investment. Discover more tips and tricks in our guide to how to protect your home.

Without doubt one of the leading home security systems is the Ring Alarm. A recently updated entry in the world of smart security, the brand certainly hasn’t wasted any time making onto our list. The system allows users to build a customizable smart security set-up that works for them. 

What's included

The second-generation 5-piece kit is probably the most popular choice for home security newcomers, as it includes only the basics to get your started. Inside is a large base station, keypad, range extender for large homes or spotty Wi-Fi, contact sensor for windows or doors, and a standalone motion sensor.

How it performs

As with the Ring Video Doorbell and Ring Stick Up Cam, you’ll need to start by connecting the Ring Alarm to the super-handy Ring app. The app can be downloaded from the app store straight on to your smartphone. From here, you can control your entire home security set-up from any location - perfect if you’re looking to keep a closer eye on your home while on vacation or away from home.

As easy as the Ring Alarm Home Security System is to install, it’s also easy to take down when the time comes. So if you’re a renter or just don’t see yourself living in your current home forever, there’s no need to worry about having wasted your money on a system that you can’t take with you.

Perfect for those who like the idea of smart home security but don’t quite feel comfortable with having cameras around their home, the Ring Alarm covers all of the basic security bases for an instantly safer home without video surveillance being necessary.

Anything else?

What dramatically cuts the cost of this home security system compared with similar models is the DIY element. As professional installation isn’t required, you can simply install it yourself wherever necessary with no costs incurred. 

And it’s just as easy to connect the home security system to an existing Ring Video Doorbell or Ring Security Camera, if you’d like the best of both worlds.

The Canary All-in-One Indoor Security System is a simple, high-quality system that won’t look out of place in your living room or anywhere else you choose to put it. The system monitors your home while looking sleek and stylish at the same time.

What's included

Incredibly, this offering from Canary comes in the smallest package of all. With just a single device acting as the base station, security camera, motion sensor and siren all in one, you won't need to fiddle around with lots of different sensors and gadgets if that's not your thing.

How it performs

Whether you place it on your coffee table or over on the sideboard, the high-quality 1080p HD camera will stream real-time video to the connected app, enabling you to check up on home wherever you happen to be at the time.

If your device does happen to pick up anything out of the ordinary, it’ll send a notification to your phone (or any other first responders you’ve listed) so you can see what’s happening. This allows you to quickly tap through to the authorities. You won’t miss the 90dB+ siren, either.

There’s a built-in speaker and microphone, too, so you can talk through the camera if you have a Canary Membership.

Thanks to automatic night vision, it’s possible to monitor the security of your home around the clock. So, if you hear a bump in the middle of the night you can check what’s going on without even having to get out of the safety of your bed.

Unlike some systems, this model doesn’t require installation, meaning it can be set up in a matter of minutes. Simply download the free accompanying app and place your camera in your desired location. Connect it to the internet and you’re done!

As if keeping your home secure wasn’t enough, this offering from Canary also monitors air quality, temperature and humidity, so you can improve the overall health of your home. Finally, it has a privacy mode that completely shuts down the camera and microphone.

Anything else?

And if you’re looking to share responsibility for monitoring your home’s security, it’s worth noting that more than one smartphone can be connected to the camera via the app.

What will I need to get started with my home security system? 

If you’re buying a home security system off the shelf, then you’ll need to think about what your chosen kit includes. Do you want cameras or sensors to be installed somewhere out of the way or somewhere you can access easily? Would you be better suited to a freestanding model that doesn’t require professional installation and can be placed on a bookshelf, coffee table or somewhere similar?

You should also make sure your chosen system is compatible with your existing tech, such as an Alexa or Google Home, or iOS and Android smartphones.

 Can I use my home security system outside? 

Your ability to install cameras and other accessories outside depends on the security system you choose. While some will specify that devices are water and weatherproof, that’s not always the case so make sure you check before committing to any particular set-up. 

 Can I expand my smart home system in the future? 

Most (but not all) smart products on the market come with compatibility with common smart home hubs such as Amazon Alex and Google Home, making it entirely possible for consumers to build out their smart home system as time goes on. This is perfect for both those who are just dipping their toe into this world, and those who already have a a smart ecosystem in place. 

 What is the best home security system? 

The best home security system is hands-down the Ring Alarm Home Security System, which offers DIY-installation and a completely customisable home security set-up for a pretty affordable price point. You can control your entire home security system from your smartphone, connecting it to other Ring devices such as video doorbells. And if you’re thinking of moving, then the Ring Alarm is super-easy to uninstall and take with you wherever you go.
