Thermal imaging is a proven tool for routine patrol operations and is in use today by hundreds of municiple law enforcement agencies across the U.S. and abroad. Officers can quickly scan between homes and buildings, see into dark garages and under vehicles, and scan parking lots, where they can see suspects hiding between cars and can identify vehicles that were recently driven. When used in total darkness, officers can go undetected, as they search for prowlers, peeping toms, and other criminal mischief.
