Face Recognition is a feature of the Home app and not of the Wemo Doorbell. Facial recognition analysis is all done locally in your home and requires the use of a Home Hub to do the processing. No data is transmitted over the internet for facial recognition and it can be turned OFF at any point. For more information, please refer to the Home app.
How to enable or disable Face Recognition
Step 1: Open the Apple® Home app and locate the tile for your doorbell.
Step 2: Tap on the tile to load the camera view then tap on the gear icon to bring up the doorbell settings.
Step 3: Tap on Face Recognition to open the facial recognition settings.
Step 4: Tap on the slider to enable or disable Face Recognition. Green means enabled while gray means disabled.
QUICK TIP: Connect an iCloud® photo library to help with recognition.
Tapping on a tile adds a name to a face.
How to associate names to recognized faces
On the Face Recognition settings screen, you will see a list of people that the camera has seen but does not recognize. Tapping on a tile allows you to associate a name to the person in the photo.
