Which of the following is not a common component of a sophisticated multi-camera CCTV system?

• A. Audio recorders
• B. Surveillance cameras
• C. DVR/NVR
• D. Network switches

Answer: (A)

Video capture, storage, and data transport form the core of a sophisticated multi-camera CCTV setup. Surveillance cameras provide the image data, a DVR or NVR stores and allows playback of that footage, and network switches or similar infrastructure move video streams between cameras, the recording device, and monitoring or remote access endpoints. Audio recorders are not a standard component in most multi-camera CCTV systems. While some installations may add audio capabilities, they’re typically optional and often handled by cameras with built-in microphones or by an integrated audio feed in the recording device rather than by a separate stand-alone audio recorder. Therefore, an audio recorder is not commonly part of the main system.
