Floating orb freezes and transforms

I’ve noticed floating orbs in the past but today is intense. Non-stop motion alerts and the orb is visible when you go live. Ring is saying “person detected.” I do not hear any sounds that could provide a clue if it’s a fly or something. It’s certainly not a spider. At the end of this clip, the orb freezes and then transforms!! What the heck is going on? What is it?
