Which of the following statements about CCTV system components is correct?

CCTV systems are comprehensive surveillance solutions that integrate multiple components to provide effective monitoring and security. The statement correctly identifies the essential parts of a typical CCTV system: sensors (cameras), control units, transmission lines, and monitor units.

Sensors, such as cameras, capture video footage of the monitored area. Control units manage the functions of the cameras, including adjusting settings and managing operational tasks. Transmission lines are responsible for transmitting the video data from the cameras to the control units or monitors, utilizing various technologies such as coaxial cables, fiber optics, or wireless transmission. Monitor units display the incoming video feed for real-time observation or further evaluation.

This multi-faceted integration allows CCTV systems to not only capture and record video but also to provide real-time surveillance and facilitate proactive security measures. By incorporating sensors and additional components, the functionality and effectiveness of the CCTV system are enhanced, moving beyond simple recording capabilities or just relying on cameras alone.
