Just one plastic lens to protect the camera from the elements. What's odd is after the last pic it appears the deer is spooked about about to bolt the camera was knocked over. By a deer I'm sure. Thought it was interesting and odd. I was thinking in the pics with the 4 lights it could have been a chopper but this place is many many miles out in the middle of nowhere. 20+ milesThe last two look like glare from the deer. In the third image the spots are blurred as much as the deer, whereas in the spots are sharp and the deer isn't moving. The first could be a plane or meteor.
How many layers of plastic/glass are there between the world and the imaging sensor?
