Nest Detect Sensor

The Sensor That Looks Out for Doors, Windows and Rooms
  • Nest Detect can sense when a door or window opens and closes
  • Detects motion when placed on a door or in a room (up to 15 ft away)
  • Nest Detect is easy to install using the Nest app
  • You can see the status of each sensor using Nest app
  • Works with Nest Guard to sound the alarm
  • Nest Detect has damper detection, so you’ll know when someone is messing with it.

  • What's Included
  • One sensor can sense two things.

    Stick Nest Detect on a window and you’ll know when it opens. Stick it on a wall and it senses motion in a room. Better yet, stick it on a door and it can do both.

    And it can do more than sense.

    Say the house is armed and you need to leave early or let the dog out. Just press the button on Nest Detect when you open the door. With Quiet Open, the house stays armed and the alarm stays silent. And when you walk past Nest Detect at night, Pathlight helps you see in the dark.

    Always know what's happening at home.**

    If the alarm goes off, you’ll get a security alert on your phone.* Check the free Nest app to see what triggered the alarm – either a door or window opened or someone entered a room. Then you can call the police or your emergency contacts.
