Nest Protect


The creator of the iPod starts a new revolution with this smart smoke alarm

Looks superb ; Easy to install ; Works flawlessly ; Polished browser & app UI ; Brings peace of mind

Costs 10-20x a dumb alarm

This means, for example, should the Protect detect gas it can tell the Nest thermostat to switch it off. This is where the Internet of Things and ecosystems within it become even more interesting.

Nest Protect review


Nest, known in the United States for its intelligent thermostat system that can be controlled via your iPhone, has launched an intelligent smoke and CO2 detector called Nest Protect. There is no doubting the Nest Protect is a very clever device that...

Monitor status via your phone, acts as a nightlight, battery lasts for 5 years, will connects to other Nest products, speaks to you, wave to turn off alarm

Expensive, need to have Wi-Fi for it to work, other Nest products absent from UK at time of writing

There is no doubting the Nest Protect is a very clever device that works as prescribed and achieves what it sets out to do. It looks good, can communicate with other Nest devices, and thanks to the app you can even detect a fire when not in the home....

Nest Protect review


How do you make a smoke detector cool? It's hard, and more difficult still to glamorize a carbon monoxide detector. Under ideal circumstances, you'll never hear a peep out of either.

With boutique design, remote monitoring via mobile device, and the ability to wave off false alarms with your hand, the Nest Protect is the smoke/CO detector we never knew we wanted.

$129 is a lot to ask for a smoke/CO detector, even a connected one.

Nest brings crisp design and smart features -- connected and otherwise -- to the humble smoke detector. You don't absolutely need the Nest Protect, but it's fine to admit you want one.

Nest Protect review: A superb smoke detector gets cheaper


A superb smoke detector and the shape of things to come for the connected home

There's no doubt that Protect is an effective detector that should give you greater peace of mind than a regular alarm, as it's easier to monitor and won't annoy you with false alarms or low battery warnings. However, you pay for this convenience. A...

Nest Protect review


Functional and far smarter than your old smoke detector, the Nest Protect is back -- minus the gesture recognition. But more work is still need to make the smart home truly brilliant.

Nest Protect review: a smoke detector for the smartphone generation


The Protect brings plenty of innovation to the staid world of smoke detectors, but the $99 price will be too steep for many people to swallow.

Remote control via a mobile app ; Clever uses of color notifications ; Sleek design

Expensive for a smoke detector
