A system whose most common use is that of inspecting conduits such as sewers, drainage pipes, water, gas and oil conduits. Contrary to camera systems currently on the market, the system has individual components that are easil y disconnected and reconnected so that a failed component can be determined an d replaced in the field, yet it maintains its integrity against damage from the type of effluent in which it is required to operate. The system's control unit is easily disconnected and replaced, and is mounted on a carrier. The system includes a push rod assemb ly that has male or female plugs providing quick disconnects at each end so that it can readily be disconnected from opposite gender plugs on a rotary contact assembly at one end and a video camera assembly at its other end. The rotary contact assembly is mount ed on the carrier and is similarly connected to and from the control unit, which is physically separate and is also mounted on the carrier. The carrier also has a reel on which the push rod assembly is stored.. Electrical power is provided from a power source fo r the camera and the video equipment that receives video signals from the camera. The pow er source may or may not be mounted upon the carrier. The novel splices between the wires of various units and eithera male or a female plug by which units are connected are a major contribution to the success of the invention. Similar splices can also be us ed for field repairs to damaged push rod assemblies or for increasing the overall length of the push rod assembly.
