Subject is a 300#, 6'3" man (a big boy). Video begins with subject at 10-feet and walks out to approximately 75 yards. Coming back, a 70# yellow lab joins in the video at about 30-yards from the FLIR / iPhone.
Time is approximately midnight, temperature is about 60*F, weather is perfectly CLEAR skies with a 3/4 moon (excellent visibility) and near ZERO humidity -- i.e. a crisp, cool, clear night. The "Colorful" pallet is the one that seems to provide the most contrast for "distant" human detection. Conditions were just about ideal to determine maximum practical detection range. I'm in shorts, flip-flops, and a t-shirt to maximize thermal signature.
Maximum detection range for a 70# dog is about 50-60 yards.
