A drain camera is a specialized inspection tool used to visually assess the condition of drains, pipes, and sewer lines. It consists of a high-resolution camera attached to a flexible cable that is fed through the drainage system. The camera transmits real-time footage to a monitor, allowing operators to inspect for blockages, damage, or other issues without the need for excavation. Drain cameras are commonly used for routine inspections, troubleshooting, and locating problems like leaks, cracks, or tree root intrusions, helping to improve maintenance efficiency and reduce repair costs.
