What is a camera drop with a plumbing inspection?

A camera drop in a plumbing inspection is when a plumber inserts a small waterproof video camera into a pipe (usually through a cleanout or drain opening) to visually inspect the inside of the plumbing line.

What it’s used for

The camera—often called a sewer scope camera—travels through your pipes and sends live video back to a monitor. This allows the inspector to identify issues like:

• Cracks or breaks in the pipe
• Tree root intrusion
• Blockages or buildup (grease, debris)
• Pipe misalignment or “bellies” (sagging sections)
• Corrosion or deterioration

Why it matters (especially in real estate)

In home purchases, a camera drop is commonly used to inspect the main sewer line, which is one of the most expensive systems to repair. A standard home inspection usually doesn’t include this, so it’s often done as an add-on.

How it’s done

• The plumber locates a cleanout access point
• Feeds the camera through the line toward the street
• Records the footage (you can often watch in real time)
• Marks distances to pinpoint where any issue is located

Cost range

In areas of Chicago and surrounding suburbs, a camera drop typically costs:

• $150–$400 depending on the company and scope

Bottom line

A camera drop gives you eyes inside the pipes, helping catch costly underground problems before they become your responsibility.
