Which component is essential for connecting coaxial cameras to switches in a CCTV system?

• A. A transceiver
• B. A balun
• C. A bridge
• D. A splitter

Answer: (B)

In a CCTV system, when dealing with coaxial cameras, a balun is essential for connecting these cameras to network switches. A balun serves as a transformer that allows for the transmission of video signals over unshielded twisted pair (UTP) cabling. This is particularly important when integrating analog coaxial cameras into digital network environments, as the balun helps to convert the signal from coaxial to a format that can be transmitted over Ethernet or other networking cabling. Furthermore, utilizing a balun can also enhance the performance of the video signal, reducing interference and allowing for longer cable runs without significant signal loss. This makes it a critical component in systems where analog cameras need to be connected to digital infrastructures, ensuring that the video quality is maintained and that seamless communication between devices is achieved.
