Cabin Camera
Your Model 3 is equipped with a cabin camera located above the rear view mirror.

For vehicles that are not equipped with Full Self-Driving (Supervised), the cabin camera is not currently active. If used in a future safety feature, Tesla will notify you of its availability through a software update.
For vehicles that are equipped with Full Self-Driving (Supervised), the cabin camera can determine driver inattentiveness and provide you with audible alerts, to remind you to keep your eyes on the road when Autopilot is engaged. For more information, see Full Self-Driving (Supervised) (If Equipped).
Images and video from the camera do not leave the vehicle itself and are not transmitted to anyone, including Tesla. Cabin camera does not perform facial recognition or any other method of identity verification.
