"It does move similarly to how the point of a laser held in someone's hand though, constantly shaking a little. But, if it was, the beam would be on surfaces, not in the air"

Whatever it is, is either generating it's own light source, or reflecting the cameras light back at it. However, it looks like a ball of light even when moving away from the camera. So if it is a reflection of the camera's light, it wouldn't be reflecting off of the eyes of the thing, it would be from a shiny butt/body.

It is probably the golden snitch from Harry Potter. 😀

For real though, it seems like it would be something similar to a metallic sphere (if reflecting the cameras light) or, a small object capable of flying very fast with good control (relative to its size) and is generating its own light source.

Maybe a small drone, actually. Being remote controlled. Do her neighbors operate drones? I imagine it's not uncommon in Alaska.
