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.

Free from security cameras

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.

That said, 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.

High-quality camera

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.

Night vision

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.

No installation required

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!

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.
