With Nest Aware, you can use familiar face detection1 to teach your Google Nest camera to recognize faces of people that you know, and notify you when it detects people it doesn’t recognize. Over time, facial recognition becomes more accurate at determining familiar faces and can send you more helpful alerts.
You can also manage your familiar faces library in the app, like change a person’s name or delete a face profile.
Important: Use familiar face detection in compliance with the law. Depending on where you live, you might need to get consent to have your camera help you identify people who visit your home.
How familiar face detection works
Note: You need a Nest Aware subscription to use familiar face detection.
Basics
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.
Face library
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.
Recorded video and camera events
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.
Notifications
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.
How familiar face detection works with two or more cameras
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.

Privacy and control
How Nest cameras and doorbells store face data
Older Nest camera and doorbell models that are set up in the Nest app store familiar face data to the cloud. To help protect user privacy, this data is encrypted and is not accessed by Google.
Newer Nest camera and doorbell models that are set up in the Home app store familiar face data locally in its internal memory.
To help protect user privacy, locally-stored familiar face data is also encrypted. For security reasons, the internal memory for these devices is not accessible or removable.
Age-restricted access for familiar face detection
Note: This only applies to people who manage home members in the Home app.
To help ensure privacy and safety, home members in the Home app who are under the age of 13 in the US (or the applicable age in your country) have limited access to the familiar face detection feature. This means:
- They can’t change familiar face detection settings or access the familiar face library.
- They can’t turn on familiar face detection when setting up a new camera with a Nest Aware subscription.
- They can still check familiar and unfamiliar face events in the Home app and Nest app.
- They can still receive familiar face alerts from the Nest app.
When a home member under the age of 13 (or the applicable age in your country) enters their date of birth into their Google Account, they are prompted to switch to a supervised account.
An email from Google will be sent to let them know that their access has changed.
(1) Nest’s familiar face detection feature is not available on Nest cameras used in Illinois. Certain state legislation may affect Illinois customers’ use of the feature, so we disabled it as a precaution. If the home where you’re using your camera is in Illinois, you shouldn’t be able to turn on familiar face detection in the Nest app.
Use familiar face detection in compliance with the law. Depending on where you live, you might need to get consent to have your camera help identify people visiting your home.
