Has anyone seen this before? Windshield blocking IR light

[MD JD]

Got a rat problem in the garage. Bought an infrared camera. Suddenly see this:

It looks to me that the windshield reflected 100% of the IR light from the camera. My wife went inside the car and I couldn't see anything from the camera's eyes. Interesting.

And what's that crack-like thing in the middle of the windshield? Looks like a wire or something.

Reflection of the garage door track?

IR will reflect off of glass. Put an IR camera behind a window and you will only see a reflection. Looks like the lines are reflections too - probably the garage door track and a conduit.

Your garage door opener track (it looks like you can see the garage door opener itself reflected in the top of the windshield), and a while power cord that appears to be running across your ceiling to your garage door opener (look at your ceiling and then look at the picture).

FYI: I presume this is to help keep the A/C cooling energy down in the car... and it filters out all the skin cancer causing rays. In the old days people used to get a tan keeping their arms on the window sill. These days you have to keep the window open to do that... not that I would recommend that.

Depends on if the side windows are laminated. ala -->
"Laminated glass is made from laminated plastic between two layers of glass, which is known to block 98–99% of all UV light. The problem, though, is that windshields only protect the front side of your face. The side window of your car is made out of a different type of glass (tempered glass). Tempered glass is known to block 60–70% of UVB rays, but not UVA."

How much UV radiation seeps through the windows we spend so much time behind?
