your right flir cant see threw walls that are properly insulated with an air gap between the walls thats the same temp as the rest of the house. but if the house is porly insulated the heat sign will glow right threw the wall roof etc. most people dont know that the flir in most the choppers in populated areas has been upgraded to see threw walls and pick up heat signatures due to all the bs thats goin on in the world these days like kidnaping for ransom to name 1. old flir (the 1 they sell to the public) couldnt see threw glass because it would just reflect off it thats not the case anymore with their new flir. just sayin never underestimate the government.
