I’ve been capturing these things on our camera.
they don’t seem to act like bugs
flying bugs that are very IR reflective and too fast to be captured in a still frame
First one just looks like a dust orb illuminated by the IR. Very common, and even more so when there is air movement or the camera is outside.
definitely dust. rain looks awesome under IR… looks like old school TV static!
If this were ghost adventures we would claim the movement indicates that you captured an entity. But since you want an honest answer I would say that looks alot like dust moving around and rising from an upward draft caused by uneven room temperature. But entity does make it sound cooler…
