C-Mount CCTV cameras use detachable lenses and can cover distances beyond 40 ft, with the ability to use different lenses as distance requires. Which option reflects this?

C-Mount CCTV cameras use detachable lenses and can cover distances beyond 40 ft, with the ability to use different lenses as distance requires. Which option reflects this?

• A. Detachable lenses that allow longer focal lengths
• B. Fixed lens only
• C. Wireless-only operation
• D. Indoor use only

Answer: (A)

The key idea is that C-Mount CCTV cameras use detachable lenses, which lets you swap in lenses with different focal lengths. A longer focal length narrows the scene and magnifies distant objects, enabling you to cover farther distances—like beyond 40 ft—while a shorter focal length gives a wider view for closer areas. Because the lens is detachable, you can change lenses as distance needs change, making the system versatile for different surveillance scenarios. That’s why the best choice is detachable lenses that allow longer focal lengths. A fixed lens wouldn’t let you adjust for distance, wireless-only operation isn’t about lens flexibility, and indoor use only isn’t related to the capability to change lenses or cover longer distances.
