Help identify a strange object on my ring IR doorbell camera.

[David M.]

I noticed a small white "worm like" object that almost appeared to be swimming/ flying through the air that seemed to appear almost immediately after she entered the house from above her car following her path towards the front door and briefly pausing when it reached the porch then turning to the left (her right) flew a few feet before seeming to just fade away before leaving the view of the camera.
I've seen and understand what insects look like on ir camera footage but this doesn't look like anything I've seen before.
Lmk your opinions please, can this be explained with science/ frame shutting or possibly... supernatural?

To me it looks like a windblown bit of thread, perhaps spider silk or some vegetation, it likely shows up as it enters the light and vanishes as it leaves it.

Possibly disturbed by the door, likely pretty small but close to the camera lens.
