FLIR K45, K55 and K65 Thermal imaging cameras

K Series Now with FSX

FSX enhances K45, K55 and K65 thermal images through real-time digital processing inside the camera. The result is an ultra-sharp image that shows extraordinary structural, edge, and other instantly-recognizable detail.

FLIR K-Series Featuring the NFPA®-Compliant K65

In the heat of the battle, a thermal imaging camera is indispensable – a vital tool that helps you quickly visualize your plan of attack, locate hot spots, and save lives. Ideally, every engine and truck company should have at least one high-performance TIC on hand. Since FLIR K-Series arrived on the scene, now that’s more feasible.

Affordable K-Series TICs offer new, easier ways to see more clearly in the darkest, smokiest environments by showing big, bright FLIR images to help you maneuver more strategically, stay better oriented, and find victims faster. With greater situational awareness, you’ll improve safety and the likelihood of successful outcomes.




Clear and Crisp Thermal Images
The maintenance-free uncooled microbolometer sensor produces detail-rich images at 320 x 240 pixels (K55 & K65) and 240 x 180 pixels (K45) Thermal images are displayed on a large bright 4” LCD, helping you navigate easier and make more efficient, accurate decisions.

FSX™ Flexible Scene Enhancement (K45, K55, K65 only)
FSX enhances K45, K55, and K65 thermal images through real-time digital processing inside the camera. The result is an ultra-sharp image that shows extraordinary structural, edge, and other instantly-recognizable detail. This helps make it much easier for firefighters and rescue teams to find their way through the smokiest, darkest environments, and to instantly identify targets in scenes with extreme temperature dynamics.
