Ever get this working?

The two-way audio on my Hosafe camera also doesn't work in ONVIF mode. (The sound actually comes out my PC speakers, which is weird as hell.)

Changing the audio stream from a to u and/or enabling the RTSP talkback also reverts itself every time, as you mentioned.

Yeah, it really is Wild West, huh? Especially with all these tiny manufacturers all over Amazon and such. Like I said, j just tried two cameras (a Genbolt and a Swann) that did not play ball with Blue Iris. Next I will be trying a Hosafe camera. I preemptively contacted their support team about Blue...

Ah, okay, the DIO were missing from the PTZ menu in the last two cameras I tried.

Guess I'll just keep looking.

All I want is a 2K or better picture, two-way audio, and PTZ.

The floodlights are a nice touch, but if they're rarely compatible, I guess I could do without it.

I know there is a setting in the PTZ controls for turning IR on/off/auto. Are there any cameras with floodlights that Blue Iris has the capability/compatibility to turn on/off, or is that functionality the cost of going with third-party control software? If I'm mistaken, and Blue Iris can indeed do ...
