Check out this helmet camera video captured at a house fire in Durham, North Carolina.
I still think that the helmet camera has excellent use for training.
The video states:
Durham Fire Department in the Bull City NC. Riding with B shift Ladder 1 on a single story duplex fire. Quick knockdown and vertical ventilation. Units responding; E-1, L-1, Sq-1, B-1 first due district, E-2, L-2, B-2, E-9 second due district.
