A push camera is usually simpler when the line diameter, distance and bend path allow an operator to advance a rod from one access point. A crawler is better for larger, longer or difficult mains that need powered travel and controlled viewing. If pushing will be unreliable, added cable length is not the solution.For distances over 350 feet, a pipe inspection robot is often the better option.
Straight-view heads suit routine blockage and condition checks. Self-leveling heads keep the image upright and make the whole inspection process much more convenient. Pan-and-tilt heads let the operator inspect joints, laterals and sidewalls more closely, but they usually require more clearance. Choose from the smallest restriction and the detail the report must show.
A sonde-equipped camera can help locate the head and estimate the surface position of a blockage or defect when used with a compatible receiver. Accuracy depends on depth, soil, pipe material, nearby utilities and technique. Use the video, footage counter and locator together rather than treating any one reading as exact. Most of our systems come with a built-in 512Hz sonde that meets North American standards. You can pair the sewer inspection system with a locator to receive an additional discount when purchasing both as a set.
Check the complete working range, not only whether the head fits through the opening. Head diameter, skid size, push-rod stiffness, bends, offsets and debris all affect performance. In larger mains, use a compatible skid or roller assembly to center the camera and improve the view; in smaller lines, remove unnecessary bulk. If the pipe is clean and without bends, a 1" clearance can be sufficient. Please consult our sales assistant to confirm a suitable configuration for your needs.
