Helmet recorder

Helmet recorders are standard field issue equipment for UNSC Marines.

When in combat with an enemy, they are instructed to turn these recorders on to get as much information on the Covenant as possible, such as behavior and tactics. Because such data is scarce, the helmet recorder is an invaluable tactical resource to the ONI and the UNSC forces, who often retrieve this data and then debrief the wearer about the audio and video data they recorded. They store their information in the processed Recorder Chips.

The recorder is equipped with a night vision function, though picture quality is said to be poor. Curiously, it appears that these cameras stop recording when the user is incapacitated, such as when PFC Wallace Jenkins was attacked by the Flood. It may be that the impact simply caused an equipment malfunction.

Covenant Ossoonas are equipped with similar helmet-mounted recording units.

Use

 * SPARTAN-117 was equipped with something similar to a helmet recorder during the Battle of Sigma Octanus IV. A fiber-optic cable equipped with a camera, he used this device to record an Engineer taking apart a car.
 * During the Battle of Installation 04, SPARTAN-117 got his first glimpse of the Flood while watching a recording he found in Private First Class Jenkins' helmet.
