Nest Protect

The smoke alarm that thinks, speaks and alerts your phone.

The alarm goes off and your mind starts to race.

  • Where’s the problem?
  • Is it smoke?  CO?
  • Burnt toast?

It’s time to expect more from your smoke alarm.

The Nest Protect has been redesigned from the inside out. It has an industrial-grade smoke sensor, tests itself automatically, and lasts up to a decade. It's also the first home alarm you can hush from your phone without any extra hardware required. And just like the original Nest Protect, it tells you what’s wrong and can even alert your phone.

Meet the Nest Protect. There’s never been a smoke alarm like this before.

Count sheep, not chirps.

No one should be woken up by a low-battery chirp at two in the morning. When you turn off the lights, look for a quick green glow. That's our Nightly Promise. It means that all your Nest Protects have tested themselves, the batteries are fine and there won't be any chirps. Sweet dreams.

A Nest home.

Nest products are made to work together. And they can even work with lights, locks and other products in your home.

  • If your Nest Protect senses smoke or carbon monoxide, Nest Cam will automatically record and send you a video clip if it's connected to Wi-Fi. And the entire video will be stored securely in the cloud so that you can go back and see what happened.
