When a fire team arrives, it can become a guessing game — where's the fire actually burning, where's it spreading, is anyone still inside. Thermal changes that. Seconds after dispatch, a 911 response drone gives incident commanders a clear read on hot spots invisible to the naked eye, before a single truck is on scene.
And it doesn't stop there. As a team vents the roof, command can watch it work in real time, confirming heat's actually venting, and that it's safe to keep other crews working the fire.
