Tesla Dashcam AKA TeslaCam
Record and store video footage captured by your car’s camera onto a USB flash drive.
To record you need to do the following.
Configure a USB flash drive by formatting in the ‘FAT32’ (Windows) / ‘MS-DOS (FAT)’ (Mac) file architecture.
Add a folder in the flash drive called ‘TeslaCam’.
Insert configured USB flash drive into either of the USB ports in the front row.
Once properly configured, the Dashcam icon will be displayed in the status bar with a red dot indicating that it is recording.
Note, the USB must be plugged in while driving to record.
Be sure you have sufficient space on your flash drive to allow for saving (each minute of video recorded uses approximately 30 MB; the 1-hour circular buffer requires ~1.8 GB of free space). Dashcam is only available for Model 3, Model S and Model X cars manufactured after August 2017.
Here are some of the TeslaCam compatible devices as recommended by Tesla owners world wide.
