摘要: A television camera, scanner and amplifier all in water proof housings which are close to one another and in tandem. The camera has illuminating lamps coupled to it arranged to illuminate a space forwardly of the lens. An elongate television cable couples the scanner to a television readout screen. The housings are arranged so that they can be moved through a bend or a tee of a standard four inch salt-glazed sewer pipe.
