Obviously, most will NOT desire to disable the IR... ... it's the 'tiny' spider family that "bugs" me most. However, the IR at night is an attraction for such critters and their prey. There is also a small amount of heat generated. Logic is simple... if bugs don't come, spiders won't build. This WON'T eliminate the spider issue, but has helped on my outdoor weathercams... I generally only use the IR if precipitation is expected, and have far fewer 'tiny spider' issues. It doesn't seem to matter about the bigger 'orb' spiders... they'll build anywhere that bugs fly into and they can get anchors.... heh... using supplemental IR away from the camera several feet may help, but I'm not necessarily going to experiment with my money on that. but for security installations, might be something to think about.
