Icon on live feed

[tdac62]

Hi - when viewing a live video on the Arlo app, I noticed when I touch the screen it will fade out and a green dot with a white zig zag will appear.  I've tried to click on this dot but nothing happens, then it disappears and doesn't return until i go out of the live feed and go back in.

Any idea what this is and if we can use it?

Thank you

iOS 7 - it's something new that just started to happen but it doesn't happen all the time - it's weird
