The invention relates to an arrangement for inspecting sewer pipes or the like. The arrangement comprises a flush unit (8) that has ample room to move in a sewer pipe (10) and at the proximal end (E P) thereof substantially backwards pointing nozzles (18), a flexible flush hose (9) and liquid pressurizing means (20) in order to create a flow of the pressurized liquid (V H) through the nozzles to the sewer pipe. In addition, the arrangement comprises a camera unit n (1) including: a fish-eye lens or another lens, and in front of the lens a rotation symmetrical curved mirror, these constituting optical image forming means (5), a number of radially outwards pointed lenses in order to create an image of the circumferential zone (K i) on the inner surface of the sewer pipe; an image detector and illumination means (2). Further the arrangement includes automatic locking means (4a, 4b) for a mutual, detachable fastening of the camera unit (1) and the flush unit (8) successively in order to form a scanner combination (13), so that the optical image forming means (5) are located at the distal end (E D) of said combination.
