• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

Automated CCTV cameras frequently use motorized lenses to handle focus and exposure, with servomotors that turn the lens elements and iris based on electronic commands. The camera’s control electronics send these signals to the motors, so the iris can open or close to achieve proper exposure and the focus or zoom can adjust for sharpness and framing. This setup is standard because it enables remote and automatic tuning of image quality without manual intervention, matching the needs of surveillance systems that must adapt quickly to changing scenes. While some older or specialized setups might rely on manual adjustments or non-motorized components, in most automated systems the lens is motorized and accepts electronic control signals, making this statement true.
