Underwater video systems refers to the equipment used to capture video in water (or other liquids), and to playback the material. The equipment can be divided in components such as camera, housing, carrier (the means of moving the camera around), transmission and/or recording, and finally equipment for viewing. A basic underwater video system consists of a camera in a watertight housing, that (optionally) is being moved around on a carrier, and a way to transmit and/or record the pictures to the viewer where they are reproduced.
