Motion Tagging what is it used for?

Motion Tagging, How am I am suppose to use this? It is obvious what it does outlines motion, but live video does the same without a box dancing around the live and recorded video.

It’s just there to let you know when the camera “thinks” it sees motion. Could be helpful diagnosing problems with alerts. But I leave mine off for the most part so that it’s not there if I want to save any recorded video.

I haven’t unboxed my V2 yet (OK it’s out of the delivery cardboard). I’ma procrastinator. Does motion tagging show spirits? Por ejemplo, multiple alerts with nothing obvious there (like my V1)?
