In what situation might a backup camera be utilized during sewer inspections?

The utilization of a backup camera during sewer inspections is most relevant when the main camera is malfunctioning. In situations where the primary camera is compromised—whether due to technical issues, damage, or a failure to provide a clear view—having a backup camera ensures that inspections can continue without interruption. Backup cameras serve as a reliable alternative to gather critical information and assess the condition of sewer lines, thus maintaining the integrity of the inspection process. This scenario underscores the importance of having contingency plans and equipment that allow for ongoing operations and effective maintenance of sewer systems.

Routine inspections, nighttime inspections, and inspecting above-ground lines typically do not specifically necessitate the use of a backup camera; these situations are usually manageable with standard inspection equipment unless coupled with unforeseen technical difficulties.
