Which of the following cable types typically transmits the video from an analog security camera back to the CCTV system?
The correct answer is C. RG-59. RG-59 is a type of coaxial cable that has long been the standard for transmitting composite analog video signals in CCTV (Closed-Circuit Television) security systems. Its 75-ohm impedance matches the impedance of analog video equipment. RG-59 is thinner and lower-cost than RG-6…

Explanation
RG-59 is a type of coaxial cable that has long been the standard for transmitting composite analog video signals in CCTV (Closed-Circuit Television) security systems. Its 75-ohm impedance matches the impedance of analog video equipment. RG-59 is thinner and lower-cost than RG-6 (used for cable TV and satellite). CAT5e and CAT6 are unshielded or shielded twisted-pair Ethernet cables not natively suited for analog video without baluns. STP (Shielded Twisted Pair) is used for Ethernet in high-interference environments.
