THRU-WALL/ROOF ENDOSCOPE CAMERA

The IST Through-Wall/Roof Camera (Endoscope) Optical Inspection System is designed for viewing through the shielding wall of nuclear facilities such as a “hot cell”. The endoscope relays a view of the inside of a cell to a CCD camera on the cold side of the wall.

The through-wall/roof camera allows pan/tilt viewing into a nuclear cell. Control of pan/tilt/zoom, auto iris and focus functions can be either via a system network or PC. A prism within a non-browning glass dome tilts and rotates to provide viewing within a hemisphere.
