Abstract
An underwater surveillance apparatus includes a watertight housing having a transparent part and a video tube received in the watertight housing. The video tube has a light receiving end positioned to view through the transparent part of the watertight housing. A video cable extends from the video tube to a video monitor disposed above a surface of the body of water. The watertight housing is configured such that the transparent part of the watertight housing is urged in a direction downstream when the watertight housing is submerged in a body of fluid moving relative to the watertight housing.
