A method of inspecting a pipe, by pushing a video camera through the pipe on a cable, with a wire helical coil disposed between the video camera and a stop on the cable, the wire helical coil being long enough to permit passage of the video camera around a first bend. As the video camera is pushed into the pipe and moves around the first bend, a cable stiffener is placed on the cable to stiffen the cable in the first straight section while permitting the cable to move through the cable stiffener. The video camera is then pushed down a second straight section and around a second bend to view a third straight section. The cable stiffener comprises a rod having first and second ends, a straight slot running along the rod from the first end to the second end for receiving a cable, and the rod having an enlarged portion along part of the rod forming a centralizer.
