网上查的: your Tesla Model Y's built-in Dashcam records continuously while you are driving, saving the last hour of footage on a looped basis to a USB drive, and it can also automatically save clips during accidents or when you manually record by honking the horn or pressing the dashcam icon. The system uses the vehicle's exterior cameras to capture a 360-degree view of your surroundings, and these recordings are saved locally on a USB drive, not sent to Tesla.
自己一定要装摄像头 摄像头很便宜
