A video doorbell is the perfect gadget if you want to start converting your house into a smart home. Video doorbells, also called Wi-Fi doorbells, smart doorbells or doorbell cameras, use a camera, speaker, microphone, motion sensor and an internet connection to detect visitors and activity on your doorstep. You then see and hear live video and can talk to the visitor.

If you don’t respond, the doorbell can record the event for you to watch later – like voicemail for your home. You can also drop-in on your doorbell anytime to see live video of your front door.

We like cool gadgets here at BBC Science Focus, so we tested a selection of the best smart doorbells and picked our favourites. We chose the Arlo Video Doorbell as our top pick as the best video doorbell because it offered the best balance of price, features and performance. It’s smart enough to work out when to alert you and when to leave you alone, offers great video and audio quality and comes with a siren feature if you need to scare someone off.

However, there are as many different needs out there as there are door knockers, so read on to see which is the best smart doorbell for you.

What do I need to know before I buy a smart video doorbell?

If you have an existing, working doorbell the chances are you can install a wired smart doorbell. A wired-in buzzer is better than battery-powered because you don’t need to worry about charging it and it will ring your existing doorbell chime. They’re also more reliable for capturing all the action on your doorstep compared to their wire-free siblings, which have to “wake-up” before they start recording – resulting in the common “back of the head problem” (when all you get is a clip of someone walking away). The downside is a more complicated installation process, which you might need to call an electrician to carry out.

When it comes to security camera footage, quality matters. You want at least 1080p HD resolution or you’ll be left with barely visible recording. Super HD (1440p and higher, also known as 2K) gets you sharper, clearer images. Digital zoom, 6x or higher, is also something to consider – especially if you might want to zoom in on a licence plate number as it sideswipes your parked car. And unless you have an always lit front porch, night vision is a must.

If you just want to see who’s at your door when they’re there, and bark instructions at them from behind the safety of your smartphone screen, then you don’t need to pay a monthly subscription. But if you like the idea of literal “visual voicemail” for your house, pony up a few quid a month and get recordings of anyone who comes to your door (whether they press the button or not). Features that cut down on how many times you need to pull your phone out of your pocket to check on your front door include customisable motion zones to cut out a busy street and smart notifications that only alert you if there are people or packages on your porch. Some of these require a subscription.

Offering a good balance between price, premium features, and usability, Arlo’s Video Doorbell is our top choice for the best smart doorbell if you want a high-quality device that works reliably without being annoying.

Its standout feature – telling the difference between people, animals, vehicles, and packages, and only sending you the notifications you want – means you don’t get an alert every time a strong breeze sends a plastic bag down the street.

Being able to create motion zones – so you get alerted only when someone (or the neighbour’s cat) is in them – and the option to turn off all alerts when you are home (using the location of your phone to figure this out) ensures a smart doorbell doesn’t become just another electronic annoyance but a useful security tool.

Along with some of the best quality video we tested and a nice square video shape that shows you more of your doorstep than most, we like that it has a built-in siren you can set off from the app if you spot someone suspicious.

Another thing that sets it on top of the pile is an answering machine option. While no one ever left us a message outside of testing – possibly because most people aren’t used to talking to a doorbell – we can see potential here as smart doorbells gain popularity.
