K45, K55 & K65

Thermal imaging cameras for fire fighting applications


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.
