CA 2309018

A self propelled lateral inspection apparatus includes a body, a main camera fixed to the body, and a lateral camera movable with respect to the body into a lateral sewer pipe. A low frequency beacon is carried by the lateral camera or may be provided separately from the lateral camera. The beacon may be used to determine the position of the lateral camera in the lateral sewer pipe, or to map the lateral sewer pipe. A picture-in-picture processor is carried by the body, and permits an above-ground user to view video images from both the main and lateral cameras simultaneously on a single monitor screen.
