<p>Video inspection apparatus (10) for inspecting a pipeline. The apparatus comprises first (25) and second (29) cables windable respectively in first and second reels on a drum (13) rotatably mounted on a support (12,30). A first camera (15) is connected at one end of the first cable (25), A second camera (16) is connected at one end of the second cable (29). The first (25) and second (29) cables can each be manually unwound respectively from the first and second reels thereof in order to advance the first (15) or the second (16) cameras along the inspected pipeline. The first (25) and second (29) cables are connectable to a video display (11) so that images recorded by the first (15) and second (16) cameras can be displayed by the video display (11). The first (25) and second (29) cables are connectable to a power source (14) so that electrical power can be relayed to the first (15) and second (16) cameras. <IMAGE></p> |
