Unknown ray of light(?)

[unkn_]

Weird ray of light caught last night in front of my home. It triggered the camera motion detector, lasted a few hours and moved slowly: 

I have no explanation. Its origins are unknown. Please note that the lights on the left come from the rear reflector of my bike.

Could it be a spider web?

reflection off the edge of the lens by something slow moving.... like the moon?  Who knows.

or possible spider web catching the IR light as mentioned, get them now and then and they do weird things.

The shadow on the wall, top left, looks like a head and arm. look at the source of the shadow to see if it matches. many use infared to to make cameras see motion. then they know where to aviod them. Solution, better light source, turn off night vision and set to record. this is my next step.
