Troubleshoot familiar face detection
If you have a Google Home Premium subscription and your Google Nest camera or doorbell's familiar face detection doesnโt work, this article can help. Learn more about familiar face detection and change settings.
What your camera might misidentify
Your camera or doorbell may incorrectly identify certain people or events. Here are some examples:
- Your camera confuses a picture with a real event. For example, a t-shirt with a picture of a dog on it might trigger an animal detection event.
- If a person crawls on the ground, your camera mistakes them for a pet.
- Your camera has trouble distinguishing between close relatives.
In these scenarios, try to tweak your cameraโs view away from these objects to avoid false person or face alerts.
- When a mirror is present, your camera might mistake a person and their reflection for 2 people.
- If thereโs a TV, your camera might confuse someone on the screen as an actual person inside your home.
Remove incorrect snapshots from a face profile
If your camera identified someone incorrectly, remove incorrect snapshots in the face profile as soon as possible. This will reduce the chance of that person being misidentified again.

Make sure to turn on your camera's familiar face detection.
If you have more than one Nest camera, youโll need to turn familiar face detection on for each camera individually.
If that isnโt the issue, ensure your camera has a clear shot of the area you want to monitor. This will help your camera tell the difference between faces.
Tips to help your camera detect faces better
- Position your camera so it can find faces easily. Familiar face detection works best when the subject is directly in front of the camera.
- Place your camera roughly 6-8ft (183-244cm) above ground and place your doorbell about 4ft (122cm) above ground.
- Place the camera where people would naturally walk towards it, such as pointed at a path or down a driveway.
- For best results, the camera should be placed within 10ft of where people will walk towards it.
- Check the lighting around your camera. Check your cameraโs view at different times during the day to make sure that thereโs no glare from the sun or other light sources.
- Review your familiar faces library regularly basis in the first few weeks, especially after you add a new person. Promptly fix any face recognition mistakes.
Important: Before you change notification settings itโs important to understand how they work. Here are a few key points about familiar face notifications:
- When your camera spots a familiar face, the event includes the name (if any) you assigned to the person.
- When your camera spots an unfamiliar face, it will send an unfamiliar face alert.
- If your camera spots a familiar face and an unfamiliar face at the same time, it will send an alert about the unfamiliar face.
- If your cameraโs not sure whether it recognizes a face, it will send a person alert instead of a familiar face alert.
- You might get different alerts for the same person if you have more than one camera and their settings are different.
If you canโt manage your cameraโs familiar face detection settings or your homeโs familiar face library, it could be caused by the following:
- Your home is in an area where familiar face detection feature isnโt available.1
- Youโve entered your date of birth into your Google account and are under the age of 13 in the US (or the applicable age in your country).
(1) Nestโs familiar face detection feature is not available on Nest cameras used in Illinois. Certain state legislation may affect Illinois customersโ use of the feature, so weโve disabled it as a precaution. If the home where youโre using your camera is in Illinois, you shouldnโt 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.
