What type of cable is typically used for connecting analog CCTV cameras?

• A. Fiber optic cable
• B. Coaxial cable
• C. Twisted pair cable
• D. Ethernet cable

Answer: (B)

Coaxial cable is commonly used for connecting analog CCTV cameras due to its ability to effectively transmit video signals over longer distances with minimal interference. The inner conductor of the coaxial cable carries the video signal, while the insulating layer and the outer conductor shield help protect against electromagnetic interference. This makes coaxial cable particularly suited for the analog video transmission that characterizes traditional CCTV systems.

In contrast, fiber optic cable is typically used for high-speed data transmission over long distances rather than for analog video signals. Twisted pair cable is primarily used in networking applications for transmitting digital data, and while it can support video signal transmission in some modern setups, it is not the standard for traditional analog CCTV systems. Ethernet cable, designed for networking, is utilized in IP camera systems rather than in the context of analog cameras, which rely on coaxial connections for video transmission.
