Cam droids, also known as hovercams, were repulsorlift droids, used as self-motivated recording devices. They were essentially artificially intelligent, self-directing holocameras. Many cam droids were highly intelligent, such as the Holocam E, although others lacked all but minimal cognitive circuitry. Units such as the Senate cam droid could be programmed to favor certain political factions during recording and editing, while others, such as the journalist cam droid 3DVO, were able to seek out news stories on their own. Cam droids were also used to capture sporting events like Podraces, and their recordings would be transmitted to the public HoloNet or portable viewscreens.
