Law Enforcement

An infrared camera is an ideal tool for law enforcement agencies to detect the thermal signature of a criminal suspect in the darkness of night. The pursuit of suspects in moving vehicles at night is considerably aided by infrared technology. The vehicle's engine and its tires (because of friction with the pavement) both become hot, producing an infrared glow that is easily detected and monitored. These thermal characteristics make infrared cameras particularly useful in traffic surveillance, especially in dark or foggy conditions.

The use of IR sensors is also widespread in perimeter surveillance, in monitoring the US border for illegal immigration, the detection of concealed weapons and other hidden evidence, and for locating hidden graves. Thermal infrared evidence has been used to obtain warrants and to convict criminals and is even used by investigators to reveal hidden text. Several court precedents already exist for the use of evidence obtainable with infrared technology.
