Overview Video System

The Overview Video System (OVS) is a camera system that was designed to provide a second view of in-tank operations. It is mounted on a handtruck and is man-portable.

The cable reel mounted to the handtruck holds roughly 50 feet of umbilical, allowing the camera head to be deployed nearly 50 feet below the level at which the hand truck is parked. The video head, which descends from the umbilical, is about 3.9 inches in diameter and 48 inches long.

The camera in this unit points straight down from the bottom of the unit. A first-surface polished aluminum mirror below the camera is used to aim the camera view sideways. A pan motor in the camera head provides a panning degree of freedom. Lights in the side of the video head provide off-axis lighting; this results in improved image quality.

Originally designed and deployed in underground storage tank applications, this system has also been used to examine the drain line outlet in cell 10 of 221-U (U Plant).
