Using Thermography For Law Enforcement-ca1816

Computers-and-Technology Thermography allows law enforcement officers to view reliable infrared images of their environment. With these images, they can carry out surveillance activities, investigate crime scenes, conduct search-and-rescue operations and locate and apprehend suspects more effectively. Using infrared digital cameras also help them to detect potential dangers and enhance safety on the job. 1.Surveillance and Locating Fugitives Thermal imagers enable law enforcement officers to monitor upto 1,500 feet, greatly facilitating perimeter surveillance. Also, dark or camouflaged clothing worn by a fugitive makes it tricky for officers to locate them. The camouflage obscures night vision, too and officers cannot use flashlights as they may alert the suspect. In such a case, heat images shown by infrared digital cameras help them to distinguish the suspect from his surroundings. 2.Locating Evidence Weapons and drugs dropped by suspects generally yield infrared images. These act as evidence and help officers to determine a fugitives path of pursuit. 3.Property Scanning While thermography does not facilitate X-ray vision, it does detect heat radiated from surfaces. Law enforcement officers may use it to detect thermal irregularities like split fuel tanks, loaded tires and hollow panels. These irregularities then call for further investigation. 4.Accident Investigation When a vehicle halts rapidly, it creates friction, leaving thermal signatures on the road. Also, on busy intersections, thermal imagers help detect warmest marks, indicating those left most recently. 5.Marine Patrol Thermal imagers locate floating evidence and land masses on water surfaces effectively. Also, since the temperature of water is lower than that of a human being, a person floating on water is easy to detect with an infrared digital camera. Also, sophisticated cameras like the TI 30 are unaffected by fog, mist or smoke, which are common obstacles for officers on marine patrol. Thus, they can be used to aid surveillance, navigation and search-and-rescue operations. 6.Tactical Teams Tactical teams are a specialty area of law enforcement. Due to the high-risk nature of their job, officers from these teams use thermography for pre-entry surveillance, stealth entry, search and evidence location. 7.Safety When approaching a potentially dangerous location, officers can use infrared digital cameras to scan the situation from a distance and ensure their safety. The seven applications of infrared digital cameras listed above are some of the most common. However, the high cost of thermal imagers has resulted in limited use of it so far. With recent reductions in size and cost and increased ease of use, infrared digital cameras may soon become an integral part of a patrol officers kit. About the Author: 相关的主题文章:
