This video shows one of the most important thermal imaging training objectives: understanding how TICs transition from high sensitivity to low sensitivity — and why it matters on the fireground. High sensitivity mode provides clearer, sharper detail — especially critical during search and rescue. When the camera shifts to low sensitivity, that clarity drops. If firefighters don’t recognize the change, it can lead to misreads and missed victims. This training aligns with the new NFPA 1801 Standar
