Know more, worry less.

  • Nest Protect looks for fast burning fires, slow smoldering fires and invisible carbon monoxide (CO). It speaks up to tell you what the problem is and where it is. It can also give you a friendly heads-up before it has to sound the alarm and you can hush it with your phone.

  • In case you’re not home, Nest Protect alerts your phone when the alarm goes off or if the batteries run low. It also gives you greater peace of mind by testing itself over 400 times a day and showing you everything is working with a quick green glow when you turn off the lights.

  • For the night owls, it even lights your way in the middle of the night. And because it can be silenced through your phone, you’ll never have to wave another tea towel again. Available through iSelect, Nest Protect is a thoughtfully designed must-have for any connected home.

Protect your home in just minutes.

You can set up Nest Protect all by yourself, quickly and easily, with your iPhone, iPad or Android device and a working Wi-Fi connection.
