The conventional surveillance angle, in which activities are observed from a helmet camera mounted at the top, separates a participant of an activity, such as sports, from his immediate experience. A different point of view can be taken from the camera when it is mounted via the Y-shaped accessory mount over the apogee of the helmet chin bar. This point of view is a sousveillance in which the observation is down at a human level so as to allow a consumer of the recorded contents of the sousveillance to connect with the sportsman by vicariously undergoing the immediacy of his sporting experience.
