I have been having problems with both my Red 40 cams. 2012, and 2013 models. About 80% of my pics are all blurry. When I first got these cams, I would get a few blurry IR shots here and there, but now it seems like they are all blurry. Here are just a few from my last check.
Most any IR camera will show some blur like those depending on the amount of movement involved. I've owned some other brands that were super blurry when the deer or what ever tripped it was standing still even.
