# UniFi Protect: reconstructing siren and AI Horn audio control

> The UniFi Protect audio investigation maps private HTTP endpoints and a WebSocket talkback stream for a UNVR running Protect 7.1.x. It documents siren, TTS, ringtone and volume calls, plus AAC-LC ADTS frame pacing for the AI Horn; Python examples implement the requests.
