Camera drone

A Camera Drone is a type of sound and video recording device used by Humans. It is probably used for playback on civilian-owned video displays as entertainment or acknowledgement on current events. The Camera Drone resembles a Forerunner Sentinel. They appear to hover on several air propellers. These are probably used to broadcast the film back to Earth.
