# VTech Baby Pro Bridge: reconstructing local camera streaming

> VTech Baby Pro Bridge reconstructs local streaming from an RM-series camera through TUTK/Kalay and VTech's X25519 and ChaCha20-Poly1305 layer. Its C bridge serves video through RTSP, WebRTC and HLS, while companion scripts probe the owner's paired Android app for connection values and use SDK libraries extracted from that app.

## Requirements & limits

- **Prerequisites:** A VTech Baby Pro camera paired through the official app and a copy of the VTech Android app package are required.
- **Prerequisites:** One-time extraction requires a rooted Android phone exposing /sys/kernel/tracing, with the VTech app installed, and a macOS or Linux laptop for offset calculation and cross-compilation. Runtime requires an ARM64 Linux host on the camera's Layer 2 segment and SDK libraries extracted from the app package.
- **Testing evidence:** The author reports testing with a VTech RM5766 and a Raspberry Pi 3B+ running Debian 13.
- **License:** No licence file in the repository.
