The larger the property or premises, the larger and more complex your drainage system will be. This CCTV camera is adept at finding blockages in pipes with large diameters, because the super-sized tractor wheels place the camera at a higher level than the standard CCTV camera rigs. 

The large wheels raise the camera higher above the bottom of the pipe, where there is water flowing through. Smaller wheels would not raise the camera lens above the water, so effectively the survey would just be a blur with it being under water. Raising the lens above water level delivers a successful, clear CCTV survey.

This particular camera has just resolved a 3rd party obstruction within a large diameter trunk sewer in Newport, returning the flow to normal. All in a days work for this small but mighty piece of drainage equipment.
