ABSTRACT:
A self-contained camera enclosure provides protection from intermittent exposure to high temperatures and fire. The protection is provided without connection to electricity or water, and is practical for use in remote areas. Protection is provided by a heat-reflecting outer box containing a liner of insulating material and a frozen-liquid cooling system. A double-pane window using an outer heat-resistant glass and an inner hot mirror allow visible light to enter the enclosed camera while simultaneously blocking heat transmission. To accommodate remote camera equipment, a four-ply thermal insulation is used to protect the cable extending from the enclosure. The enclosure can accommodate different models and types of camera equipment.
