A general home inspection is largely a visual review of what the inspector can see and reach. The sewer lateral, the pipe that carries waste from the house out to the city main, runs underground, so its condition can't be judged from the surface. Most standard home inspections do not include running a camera down that line.
That lateral is typically the property owner's pipe to maintain and repair, and it's usually the single most expensive plumbing component on the property. Problems like root intrusion or a collapsed section are completely invisible until the line is scoped, or until it backs up.
A sewer camera inspection closes that gap. It's a separate, focused scan of the buried line so the pipe under the yard is a known quantity, not a question mark.
