What component is essential for capturing video in a CCTV system?

• A. Monitor
• B. Codec
• C. Camera
• D. Router

Answer: (C)

The component that is essential for capturing video in a CCTV system is the camera. The primary function of a CCTV system is to observe and record video footage of an area for security or monitoring purposes. Cameras are designed to convert light into electronic signals, which are then processed to create visible video. Without cameras, there would be no visual data to capture, making them fundamental for any CCTV setup. While monitors, codecs, and routers all play important roles in the operation of a CCTV system, they are not responsible for the initial capture of video. Monitors display the video feed, codecs compress and encode the video data for efficient storage and transmission, and routers facilitate network connections for transmitting video data over a network. However, the capture of the actual video footage is solely dependent on the cameras, thus highlighting their critical role in a CCTV system.
