OVERVIEW: Infrared (IR) Camera (2nd and 3rd Gen) are advanced passive thermal imaging devices used for surveillance, targeting, and reconnaissance, offering improved sensitivity and digital imaging capabilities over earlier models.

GENERAL DESCRIPTION: Second and third-generation IR cameras operate primarily in the mid-wave (3–5 µm) and long-wave (8–12 µm) infrared bands, providing higher resolution and better image processing than first-generation analog systems. These cameras employ cooled or uncooled IR detectors, digital signal processing, and enhanced optics to deliver clear thermal images under various environmental conditions, including low visibility and night operations. They are widely used on aircraft, UAVs, ground vehicles, and naval platforms for target detection, navigation, and situational awareness.
