Just a couple of comments on re-visiting this thread:
1. Re_Watching the original video, the audio warning took far too long to activate. A lot of theives would have broken a window and been in the car before the warning activated.
2. I wish Dahua put speakers in all their cameras. Either that, or there was either a cheap accessory speaker - mny seem to be rubbish and expensive - surely Dahua can make a quality external speaker for around a few $ in China with an MRSP of $10-15 in the US .
3. I wish for external speakers they'd put a waterproof jack socket on the bottom of the camera body so you could add a speaker without having to take the whole camera down and apart thereby messing up conenctions and adjustments. The ability simply to plug in and plug and play a speaker would make these cameras far more user friendly. The risk is someone unplugs the speaker, but TBH, is that really such a bad thing? You still have video without audio and unplugging the speaker means coming close to and looking at the camera which is almost a dead cert facial capture.

I think that audio delay is what caused them to react the way they did. It sounded like a person like their system woke them up and they saw them and got on the speaker.
Sure the audio could have started a little sooner, but if it came on at the same time as the light did, I think they would have ignored it.
They are expecting that at the same time a motion activated light comes on, so the delay has a psychological effect that caused them to scatter.

Does anyone have a 25-30W 12V horn speaker attached to the line out of a cam?
That's about the highest wattage internal amp IP66 12V speaker I can find.
I'd like to know if it would be loud enough to invoke a reaction like that.
Does anyone have a related experience one way or the other?

Getting the hang of it
Did you ever get this to work? I'm thinking of doing something similar using MQTT to turn on our driveway street lights. I use Home Assistant for all things smart home if that helps any.
