1. A device for inspecting subsidiary canals which branch off from a main drain where a camera probe (24) is deflected from the main drain pipe (10) with a deflecting frame (22;
- 76;
96) into the branching off subsidiary canal pipe (12), characterized in that the camera probe (24) is driven forward in the subsidiary canal pipe (12) by propulsion, by supplying a pressure medium to reaction jets (34;
90) mounted on the camera probe, said device including a camera probe (24) and a deflecting frame (22;
76;
96) which can be held in position in the main drain pipe (12) for deflecting the camera probe into the subsidiary canal, characterized in that the camera probe (24) is provided with reaction jets (34;
90) and is connected to a hose (36) for supplying a pressure medium to the reaction jets, wherein the reaction jets (34) are contrived on a rim (32) which encircles the periphery of the camera probe (24) at a distance from its front end, and are oriented outwards at an angle in relation to the axis of the canal probe (24).

Abstract
A process is disclosed for inspecting subsidiary canals that branch off from a main drain. A camera probe (24) is deflected from the main drain pipe (10) into the branching off subsidiary, canal pipe (12) by means of a deflecting frame (22; 76; 96). The process is characterized by a propulsion by reaction of the camera probe (24), a fluid under pressure being supplied to reaction jets (34; 90) mounted on the camera probe so as to drive the latter into the subsidiary canal pipe (12).
