Cameras are indeed a primary component of a CCTV system because they are essential for capturing video footage of the monitored area. Cameras serve as the eyes of the system, recording events and enabling surveillance in both real-time and for recorded analysis. Their various types, including fixed, PTZ (pan-tilt-zoom), and infrared cameras, allow for versatility in monitoring a range of environments and conditions.

While control towers, voice recognition software, and mobile devices might play supportive roles in some security setups, they are not fundamental components of a typical CCTV system. Control towers might be used in large facility monitoring but are not standard for every installation. Voice recognition software is not a common feature in surveillance systems, which primarily focus on visual data capture. Mobile devices can be utilized to access or view CCTV footage remotely but are not intrinsic to the operation and structure of the actual CCTV system itself.
