Abstract
A surveillance camera assembly is mounted upon a selectively raisable and lowerable support assembly provided on a hollow pole shaft. A coaxial cable is connected to the surveillance camera and extends upwardly to pass over a sheave assembly and downwardly into the interior of the pole shaft for fixed engagement with a transition plate fixedly provided on raising and lowering cable means within the pole shaft. The terminal end of the coaxial cable is located below the transition plate and is provided with an electrical plug element so as to permit engagement of the pole-mounted coaxial cable to corresponding ground-mounted coaxial cable means when the transition plate is proximate to ground level and the surveillance camera is in its raised position proximate to the top of the pole shaft.
