A visual inspection system includes a remote end [110] that is moved through a conduit with a flexible pushrod [400]. The remote end [110] having at least one carriage assembly [130] with encoders indicating a distance traveled within the conduit. The visual inspection device has a longitudinal camera to identify view down the length of the conduit, but also has at least one transverse camera [160] adapted to visually inspect an inside surface of the conduit. Also, the transverse camera [160] may be used to inspect other conduits that connect to conduit. |
