Which term refers to a system incorporating a closed circuit video camera and monitor for inspecting the interior of flues, ducts and other inaccessible areas?

• A. Video Inspection
• B. Video Telemetry
• C. Video Scan
• D. Video Monitor

Answer: (C)

The main idea is a setup that uses a closed-circuit video camera and a monitor to visually survey the inside of flues, ducts, and other hard-to-reach spaces. This kind of system is described as a video scan because it focuses on scanning the interior surfaces for details like buildup, blockages, or damage, using live video feeding to a local monitor. It’s a practical, hands-on inspection method where the operator navigates through twists and turns to capture images for documentation. Other terms are less precise: video inspection is a general phrase for looking at something with video, video telemetry implies transmitting data from sensors rather than live video, and a video monitor is only the screen, not the complete camera-and-monitor inspection setup.
