Abstract
A surveillance system in which a video camera (7) is displaceable inside a transportation tube (1) along any direction in three-dimensional space under the effect of a compressed fluid. The transportation tube (1) is provided with at least one longitudinally-extending transparent observation window (2). The camera (7) is contained in a displaceable "torpedo" (8) and has its optical axis running parallel to the axis of the tube (1), and it receives images through the window (2) by means of a mirror (11) having two faces at an angle with the common edge running vertically and intersecting the optical axis (12), thus enabling the camera to transmit simultaneous left and right looking images to a central control station by a microwave beam.
