As Internet genres go, the helmet cam video is one of the most intimate. You go where the camera operator goes. You look where the camera operator looks. And, often, as in this firefighting video, the camera operator is also part of the action.
The helmet cam is the most natural of camera angles. It is the one your eyes themselves afford you. And yet technically, it was impossible to record until recently. So, through the history of cinema, we got used to the camera's gaze, its aesthetic, its position outside the action, its pretense to objectivity, standing still while the world went on around it. The helmet cam is radically subjective, especially in its raw form.
And yet, strangely, in seeing through another's eyes with fire raging all about, I find myself drawn back to a different fiction: videogames. If you grew up in the last twenty years, you will know the helmet cam vantage point from the first-person shooters you've played: Doom, Quake, Goldeneye, Counter-Strike, Halo, Gears of War. So, it's a strange sensation watching the firefighter move through the house. You feel as if you should be able to direct his actions. Crouch, kneel, fire. Presented with what it's like to walk in another person's boots, and my mind reprocesses myself into the scene and reinserts my (false sense of) agency.
Helmet cam video of firefighting is, on its face, breathtaking. And I wonder if it wouldn't do us all some good to watch others act and know, intimately, all that we can't control.
