The FLIR K45 is an affordable TIC that gives firefighters a clear view into the darkest, smokiest environments. It displays sharp, 240 x 180 pixel thermal images on a bright 4" screen, to help firefighters navigate easier, make accurate decisions, and find victims faster. Plus the K45 features FSX™ Flexible Scene Enhancement, which intensifies structural and textural details in thermal images.

High-performance, Affordable TICs

  • Crisp, Clear Imagery

    The maintenance-free sensor produces detail-rich 240 x 180 pixels thermal images to help you navigate easier in smokey conditions.

  • Rugged and Reliable

    The K45 withstands a 2-meter drop onto concrete, is water resistant (IP67), and fully operational up to 500°F (5 minutes).

  • Expanded Warranty

    K45 cameras are protected by FLIR's 2-5-10 Warranty: 2 years for batteries, 5 for the camera, and 10 years for the detector.
