During sewer camera operation, which problem can affect image clarity due to moisture or temperature?

• A. Deep water
• B. All of the above
• C. Fogging of optical lens
• D. Offset joints

Answer: (B)

Moisture on the lens from temperature differences causes fogging, which directly blurs the image and makes details hard to see. In addition, deep water changes how light behaves inside the pipe and can reduce lighting effectiveness, lowering contrast and overall clarity. Offset joints create irregular surfaces and reflections that distort or obstruct the view, further degrading image sharpness. Since each of these situations can reduce visibility in its own way, all of the above can affect image clarity during sewer camera operation.
