Familiar face detection

Whenever your camera detects a face, the activity is marked in your camera's recorded video in the Home app or Nest app.

When your camera detects an unfamiliar face, the app should ask whether it’s someone you know. You’ll have the option to save the person’s save data in the familiar face library. This helps your camera recognize the face as someone you know.

Important: Before saving any of your camera’s face data, check your local privacy laws. If required, get the person’s permission first before saving their face data.

Depending on which Nest camera model you have, you’ll be able to change settings and manage the familiar face library in the Home app, Nest app, or both.

Whenever your camera recognizes a face, photo snapshots of the person’s face will be saved in the familiar face library. From there, you’ll be able to edit the face profile of each person and manage photos.

All home members in the app have access to the familiar face library, and may be able to categorize faces your camera detects.

When your camera recognizes a face, the activity is marked in its recorded video. You can find this information by reviewing specific camera events, or by filtering activity in your camera’s video history.

Each home member can change whether they get familiar face notifications.

If you turn familiar face detection off, your camera can still send alerts when it detects a person. However, it won’t recognize faces.

You can turn familiar face detection on or off for each camera in its settings.

Nest cameras in the same home share the same familiar face library. If you add a new camera to the same home, it uses the same familiar face library as the other cameras in your home. This means it won’t take as long to recognize certain faces.

If some cameras have a 1st gen Nest Aware subscription but others don’t, you can only use familiar face detection for the cameras with a subscription.
