# Philips Avent: reconstructing SCD923/26 local communication

> Philips Avent Local Protocols investigates the SCD923/26 baby monitor's QR pairing, encrypted control session, RTSP video and separate ADPCM audio channels. The study combines handheld firmware analysis, isolated ARM emulation and tests against a paired baby unit. It marks discovery behavior and SCD973 authentication as unresolved.

## Requirements & limits

- **Prerequisites:** The documented local interoperability tests used an SCD923/26 handheld and paired baby unit.
- **Limits:** The SCD973 diagnostic requires Python 3.10 or newer; successful SCD973 authentication remains unconfirmed.
- **License:** The diagnostic tool has a separate tools/LICENSE file; the research text has no repository-root licence file.
