Drain Camera Inspection Crawler Cameras

These motorised units propel themselves through the drainage or sewer systems on wheels or tracks with the steerable units able to negotiate their way over and around obstructions and debris, they can survey pipe sizes from 100mm to 2000mm and cable drums can come with lengths in excess of 200mtrs long.

Pan and tilt cameras are pretty much standard these days with adjustable focus and lighting, inclinometers are available for measuring gradient as is a built in sonde for sonar tracing the line of the sewer or pin pointing concealed chambers or defects.
