Hi Everybody,
I know there are quite a few of these out here, but this doesn’t appear to be dust, and seems awfully erratic to be a bug. Please give it a look and let me know what you think.
Thanks 
It appears to me to be the flight pattern of a fly.
Just a bug. I have my camera set outside and I see this all night long. Bugs seem to reflect the infrared light. You should see all the footage I have at night. Looks like flying lights everywhere.
