Sewer video camera inspection: what it is and why

Understanding the basics starts with the question: what is a sewer video camera inspection? It is a non-invasive diagnostic technique where a small, durable camera is threaded through the home’s sewer lines or pipelines. The camera transmits live images to a monitor, allowing a technician to visually assess the interior of the pipes for obstructions, cracks, joint failures, or intrusion by tree roots.

How does it work in practice? Technicians use specialized equipment that includes a flexible rod or reel and a high-definition camera head. The camera is pushed or snaked through the sewer line, sometimes reaching several dozen meters, while a guide cable helps map the path. Data is recorded, often with a report that marks each issue on a diagram of the pipe network.
