Camera capsule

摘要

A television or film camera is attached to an overhead ceiling structure, etc., on a support member which is capable of rotating or panning the camera about a vertical axis and tilting the camera about a horizontal axis. The camera and its movable support structure are enclosed in a stationary housing having a base portion adjacent the ceiling structure and a transparent dome suspended below the base portion. The dome is coated on its inside concave surface with a fine layer of chromium which renders the dome transparent from its relatively dark inside area and opaque or reflective from the lighter area outside the housing. The camera is thus able to assume an infinite number of positions and focus on various objects in its vicinity about the housing without visual detection from without the housing.
