I live in the US and have trail cameras on my property to capture wildlife, visitors, stray animals, etc. Several are equipped with infrared and I have watched hundreds of hours of video. Many videos feature a large amount of insects flying so I know what a bug looks like on infrared.
What I captured yesterday is completely different. It is a perfectly round sphere floating from one side of my driveway to the other and back again. It appears to me to be on convection currents passing between the trees that line my driveway.
I uploaded this video to Youtube and would be very grateful if you could take a look and tell me if you think it is indeed a spider floating its web between trees. Additionally, are you aware if this phenomenon has ever been captured on video before? I searched the web looking for other videos but am unable to find any.
The 'orb' appears at 10 seconds into this video.
