But both from a victim's and a firefighter's perspective, the deadliest enemy is smoke. That's why firefighting teams use special cameras that allow them to see through the smoke, rendering images based on heat rather than light. Hands-freeScott's idea was to integrate the thermal camera into the mask all firemen already use, the respirator. The new camera, called Sight, is small and -- at around 8 ounces -- light enough to not add significantly to the heft of the mask. But it projects a small thermal image inside the mask, at nine frames per second.
