Helmet recorder (Earth-5875)

Helmet recorders, also known as helmet cams, are standard-issued equipment used within the M10 Pattern Ballistic Helmet used by the UNSC Marine Corps. They serve to record the point of view of the combatant during engagements for posterior evaluation and enemy intelligence gathering. Duo to the scarcity of data on the Covenant and even less on the xenomorphs, the helmet serves as an invaluable tactical tool of the UNSC and the Office of Naval Intelligence.

Description
The helmet recorder is issued to all members of the UNSC Marine Corps, and feature a night vision function, although the quality of the picture is poor.

SPARTAN-IIs and SPARTAN-IIIs used customized helmet recorders during missions through the First Contact War. Before 2547, most of the content in the recordings were kept classified by the Office of Naval Intelligence.
