TeslaCam

TeslaCam is a hardware and software solution that expands the storage capacity of Tesla's built-in dashcam feature. It uses a Raspberry Pi Zero W to emulate a USB drive that the Tesla recognizes, then automatically archives video files to local storage, preserving footage beyond the vehicle's one-hour rolling limit.

Key Features

• USB Mass Storage Emulation — Presents an 8GB USB drive with a "TeslaCam" directory for the Tesla to write video files.
• Automatic Archiving — Periodically syncs video files from the emulated drive to a persistent storage directory on the Pi.
• Power-Aware Shutdown — Monitors Tesla power and safely shuts down the Pi when the vehicle powers off, with a final sync to preserve data.
• Storage Management — Automatically removes older files to maintain available storage space.
• Remote Sync Support — Optionally executes a custom remote sync script for offloading archived videos.

Philosophy

The project prioritizes reliability and data integrity by ensuring all video is safely archived before shutdown, leveraging the Pi's low-power hardware for seamless integration with the Tesla's power system.
