Infrarødt kamera til brug for rekognoscering fra en helikopter
Indenfor militære operationer er rekognoscering udforskning udenfor det område, der besættes af venligsindede styrker, for at at få information om omgivelserne og fjendens tilstedeværelse.
Blandt eksempler på rekognoscering er patruljering udført af tropper (eksempelvis spejderenheder eller militære efterretningsspecialister), skibe eller u-både, fly, satelitter eller ved at opsætte hemmelige observationsposter. Spionage betragtes normalt ikke som rekognoscering, da rekognoscering foretages af en militær styrkes specialenheder før hovedstyrkens ankomst; spioner er ikke-kombatanter, der opererer bag fjendens linjer.

Helicopter-mounted infrared camera (FLIR).jpg
A beach ball-sized infrared camera, part of the Forward Looking Infrared Radar (FLIR), has been mounted on the right siderail of NASA's Huey UH-1 helicopter. The helicopter has also been outfitted with a portable global positioning satellite (GPS) system to support Florida's Division of Forestry as they fight the brush fires which have been plaguing the state as a result of extremely dry conditions and lightning storms. The FLIR also includes a real-time television monitor and recorder installed inside the helicopter. While the FLIR collects temperature data and images, the GPS system provides the exact coordinates of the fires being observed and transmits the data to the firefighters on the ground. The Kennedy Space Center (KSC) security team routinely uses the FLIR equipment prior to Shuttle launch and landing activities to ensure that the area surrounding the launch pad and runway are clear of unauthorized personnel. KSC's Base Operations Contractor, EG&G Florida, operates the NASA-owned helicopter.
