Which component is primarily responsible for converting the analog video signals into digital format within a CCTV system?

• A. Monitor
• B. Encoder
• C. Decoder
• D. Switch

Answer: (B)

In a CCTV system, the encoder plays a crucial role as it is responsible for converting analog video signals into digital format. This process is essential for modern surveillance systems, especially those that utilize digital storage, internet streaming, or advanced video analytics. By transforming the analog signal into a digital format, the encoder ensures compatibility with various digital storage devices and allows for transmission over networks. The monitor is used to display video footage, but it does not perform any signal conversion. The decoder, in contrast, takes the digital signal and converts it back into an analog format for viewing or further processing. The switch helps manage data traffic within the network but does not engage in the conversion of video signals. Thus, the encoder is critical for enabling the functionalities expected from contemporary CCTV systems, such as remote access and enhanced storage capabilities.
