I know they detect at night, but what about during the day? I got reflectix insulation on my walls except there is a 6 inch by 8 ft gap at the top area where I didn't put any, only 2x4's. What if I leave that area bare or do I need to cover it. It's just a hard area to get to. A loud ass helicopter just flew over. Can they detect during the day light hours? Any one with knowledge in this area?
