Hi,I think it would be very useful to have a siren button in the app. A bit like the push to talk, you could have a siren options (noise choice selectable in options)
You see or interact with someone you wan to get rid off, or indeed alert them to the presence of the cameras so they leave.
Via live view you push the siren option and the speakers blast out the noise of your choosing
Better then me pressing the button and shouting “wwwhhooop whooOOOOoooooppop”
