Cyalume idIRt® is a non-toxic, intrusion detection infrared light emitting powder that links physical evidence of presence to a designated or targeted area. idIRt® has an appearance similar to soil, and is not detectable by the naked eye, requiring a night vision device is required to view idIRt® in the infrared spectrum. As idIRt® resembles common soil, it provides an undetectable way to guard an illuminate restricted areas, egress routes, caves, engagement areas, dead spaces and safe lanes of travel in military applications. idIRt® is also an extremely effective law enforcement tool. Officials can mark anticipated crime scenes, trespass areas, and even packages of narcotics. As the product has a slight tackiness to it, the IR illumination adheres to clothing, packages and other surfaces, even though the dirt substance may have fallen away. idIRt® emanates IR light from 36-48 hours outdoors, depending on environmental conditions. Rain or extreme moisture will dissipate the effectiveness. Indoors, or in sheltered conditions, idIRt® produces light for up to a week. idIRt® is an ITAR-controlled product, and is only available to US military and law enforcement.
