Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
In surveillance camera assembly for use with raisable and lowerable support platforms provided on high mast or pole shafts, the combination including: a surveillance camera adapted for mounting on a raisable and lowerable support platform provided on a pole shaft; a coaxial power and control cable operatively connected to said surveillance camera, said coaxial power and control cable in rollable engagement with a sheave member positioned at the top of the pole shaft, said coaxial cable fixedly attached to a transition plate fixedly provided on a raising and lowering drive cable within the pole shaft; and an electrical connector plug provided at the terminal end of said coaxial cable positioned below said transition plate, said electrical connector plug adapted to selectively engage a corresponding ground-mounted coaxial cable positioned at the base of the pole shaft.
