1. A surveillance security system comprising:
- a carriage track positioned along a path, the carriage track having a first end and a second end;
a pair of electrical conductors mounted along the path parallel to the track from the first end to the second end;
a carriage adapted to be supported by and moveable on the track;
drive means mounted on the carriage for positioning the carriage along the track, the drive means contacting the pair of electrical conductors to receive a power signal, the power signal providing sufficient electrical power to move the carriage;
camera means mounted on the carriage to monitor regions along and adjacent the path and provide an output signal representative of the monitored regions;
modulation means connected to the camera means receiving the output signal and modulating a carrier signal with the output signal, the modulation means contacting the pair of electrical conductors to transmit the modulated carrier signal on the pair of electrical conductors to a remote monitoring station connected to the pair of electrical conductors; and
termination means connected to the pair of electrical conductors remote from the modulation means for minimizing reflections of signals transmitted on the pair of electrical conductors.

Abstract
A surveillance system includes a track positioned along a selected path and a moveable carriage supported by the track. A pair of electrical conductors mounted adjacent and parallel to the track provide power to a drive assembly mounted on the carriage. Video cameras are mounted to the carriage for monitoring selected regions adjacent to the path. Output signals from the cameras are transmitted on the conductors to a remote monitoring location. In the preferred embodiment, control signals for controlling placement of the carriage along the track are also transmitted on the conductors.
