What Survey Mode Reveals During Interior Fire Operations

This video was filmed during a Max Fire Training Acquired Structure Burn & Learn session hosted by the Fosterburg Fire Department in Illinois. It demonstrates what firefighters can see when using Survey Mode thermal imaging during interior fire operations. Watch how Survey Mode reveals critical heat signatures and gray convection currents that are often missed in standard thermal imaging modes. These visual indicators provide insight into fire progression, heat movement, and developing hazards, helping firefighters make safer and more effective decisions during fire attack and overhaul. The footage shows how Mixed Gain Mode allows firefighters to view both high- and low-heat areas at the same time without freezing or switching settings. Maintaining continuous clarity helps crews keep situational awareness while interpreting fire behavior in real time. This video features the Seek AttackPRO VRS thermal imaging camera, including Survey Mode and early colorization that support improved size-ups, interior movement, and overhaul operations. Training like this allows firefighters to put reps in under controlled conditions and better understand what the fire is doing before conditions deteriorate. Special thanks to the Fosterburg Fire Department and participating mutual aid departments for their commitment to realistic training.
