Home Assistant shortens the wait for the WebRTC connection used by camera talkback. Cameras could spend ten to twenty-five seconds on an alternative video stream, or remain there without two-way audio becoming available.
The browser tries fewer redundant relay addresses and remembers cameras where WebRTC previously worked, trying that connection first on later visits. Failed connections receive up to two retries, carrying an active microphone into the replacement connection.
On three cameras in Chrome, Wendelin measured the first opening falling from twelve to twenty-six seconds to six to nine seconds. Those timings apply to that installation.
