I have a legal grow but still keep my setup as private as I possibly can. I was curious about FLIR and what could be detected a few months ago so I set my Pentax digital camera to night mode and went outside at night for a look. My room is at ground level and has only 1 window that is insulated and boarded off and I exhaust out a chimney so I figured that I was pretty safe.
I was pretty surprised to see how much heat and IR is escaping through the walls and roof so I sheeted the entire room w/2" styrofoam sheets.
Another thing I done that made even more difference was to set my 1k lights to turn OFF during the night when temperatures are lowest.
It is impossible for FLIR to work during daylight since it detects heat and Infrared deviations against a colder background, so turning your lights off at night during the 12/12 flowering cycle will give you complete security against FLIR.
Many cameras sold now offer night vision or an infrared projector which is reflected back and then detected by the camera aperture to take a picture. FLIR doesn't project IR but the detector works the same as night vision or night cameras except that it is a different wave length and it also detects heat. But a camera w/night vision will tell you if you are unknowingly advertising your grow. If you can detect IR escaping w/ a camera then you can bet that LEO can detect it from miles away w/ FLIR.
