Hey guys, i just bought a RS 425 and was trying it out before hacking it. If I take it outside in partly cloudy or clear weather and point it to the sky or horizon (away from the sun of course), it goes off. Does this mean that I have to mount the game cam in a dark wooded setting? I thought that the PIRs need both heat and motion to be activated. Plently of heat outside. Obviously, I don't want a bunch of pictures of blue sky. Also, up here in the Northwest, we get a lot of rain. Do raindrops of the PIR lens mess up the focal lenght? Should I install a rain guard over the PIR lense and glass for the camera lens as well?
