FLIR
K45
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.

K45
High Performance Tic 240 x 180 (3 button)
The FLIR K45 and K55 thermal imaging cameras (TIC) allow firefighters to see more clearly in the harshest environments, maneuver more strategically, stay better oriented, and find victims faster. Both cameras feature FLIR's proprietary FSX Flexible Scene Enhancement technology, producing ultra-sharp, finer textured images that shows subtler details.
With FLIR TICs, first responders can quickly and confidently find their way through the darkest environments, identify targets in extreme temperature settings, and make better decisions when seconds count.
Visibility is a chief concern for maintaining firefighter safety, whether you’re in the thick of fighting a fire or coordinating resources as the incident commander. Thanks to FLIR’s lineup of cost-effective handhelds, feature-rich advanced cameras, and mounted and UAS aerial options, fire departments can now afford to outfit more firefighters with TICs and monitor all angles of the scene. This is about more than seeing through a smoke-filled room: by viewing the entire scene from multiple viewpoints, incident commanders can make better decisions when directing resources. And, since FLIR TICs clearly visualize heat sources, they’re an important tool for hazmat and search and rescue operations.
