I know how important the face recognition feature of your Nest camera is. Let's see our options here to resolve this. To confirm, where are you located?
First, make sure that familiar face detection is on for your camera.
Note: If you have more than one Nest camera, you’ll need to turn familiar face detection on for each camera individually.
If that isn’t the issue, make sure your camera is placed where it can get a clear shot of the area you want to monitor. This will help your camera tell the difference between faces.
