What Is a Sewer Camera?

A sewer camera is a device designed to inspect the inside of pipelines and sewer systems, especially in narrow, dark, and complex environments, using video technology. Equipped with an HD camera and built-in LED lights, it allows users to view clogs, cracks, and other internal issues in real time.

Key Components of a Sewer Inspection Camera:

• HD Camera: A compact waterproof camera mounted at the tip of the cable.

• LED Lights: Bright lights surrounding the lens to illuminate dark pipe interiors.

• Cable/Reel: A flexible push cable ranging from 50 to 400 feet in length.

• Monitor/Control Box: Displays the live video feed and allows for recording or taking snapshots of findings.

• Transmitter (Optional): Used with a surface locator to help pinpoint the camera’s underground position.

Sewer cameras are commonly used in both residential and commercial settings, especially before major repairs, renovations, or real estate transactions, to check for blockages, assess pipe conditions, and understand the pipe layout.

🔍 How do Sewer Cameras Work?

Using a sewer camera is actually pretty straightforward. You start by feeding the small, waterproof camera into a cleanout or drain opening. As you gently push the flexible cable forward, the built-in LED lights illuminate the inside of the pipe, allowing the camera to navigate through dark and tight spaces. The real-time video feed appears on a monitor, so you can see exactly what’s going on beneath the surface—  including blockages, cracks, tree root intrusion, corrosion, etc.

Some advanced models even come with a built-in transmitter that can send a signal to a locating tool on the ground. This can help you pinpoint the location of any problems without unnecessary digging. In addition, most cameras support recording video or taking photos so that you can review the footage later, share it with a plumber, or save it for your records.

🚨 What Can Sewer Cameras Detect?
