Smart doorbells mean you don't have to run before the delivery agent has sped off, and you don't even have to be at home to answer the door.

Smart doorbells are really a variant of the smart camera, but one that replaces your doorbell, so instead of ringing a bell – which you may or may not be within earshot of – visitors trigger a phone alert.

In fact, many smart doorbells consider the traditional ringer an optional extra, sold at more cost than a complete 'dumb' doorbell.

That said the key advantage, of course, is simply not missing anyone.

When someone presses the doorbell, even if you're at the bottom of the garden or away on holiday, the chances are you'll have your phone with you.

Just as with security smart cameras, there will be a two-way talk feature, so that you can not only see who has pressed the button, but also speak to them.

Maybe it's a visitor you were expecting but you popped out to the shop to stock up on supplies – you can just tell them you'll be there in a moment.

Or perhaps it's a sales caller, in which case no need to get up!

If you've fitted a smart lock and a smart doorbell, you have all you need to let people in remotely.

If they're from the same brand (or a linked brand, like the Yale/Nest lock) then you might even be able to control them without swapping apps on your phone.

So picture the scenario: the Amazon guy arrives just after three and presses the doorbell.

You're still at the office, but you get an instant alert on your phone, check it, and speak to the delivery driver.

Tell him to open the door, leave the parcel inside, then close the door behind him.

You can keep an eye on him as he does this with the camera and check the lock is locked with the lock app.

If all goes well the package will be indoors when you get home and you won't have to disturb your neighbours or go to the depot.

Of course, if the driver needs a signature, or doesn't manage to close the door behind him properly so the lock can't engage there are problems, but the manufacturers are less keen on mentioning these.

Doorbells are also capable of using their smarts to keep an eye on your doorstep for suspicious activities and can usually be set up to alert you when someone is near, even if they don't press the button.



A visitor is likely to be taller than the button's positioning, so their face will only occupy a small part of the picture you're seeing.

1080HD video is considerably better than 720p in terms of quality.


Many of the big brands require connection to a traditional doorbell wire, but many homes don't have these as plenty of dumb doorbells are wireless.


Usually described in terms of degrees (ie 185° field of view), anything over 180 is quite large which is useful but may also lead to a fish-eye effect.


This will let you know if someone is near the doorbell but doesn't actually press it -you can designate the active area using the app.

Amazon's Ring Doorbell was one of the first well-known brands on the market.

Elago Silicone Case for Google Nest Hello Doorbell

Just as with phones, a market in protective cases for the better-known brands of smart doorbells has sprung up, and it's not the worst idea at all; regrettably a very nice doorbell might occasionally attract the wrong kind of attention, so while no extra protection from water is needed, a covering like this from Elago still doesn't hurt.
