Which component helps provide power to CCTV systems in a centralized manner?

• A. Camera module
• B. Power supply unit (PSU)
• C. Video storage unit
• D. Network switch

Answer: (B)

The power supply unit (PSU) is essential for providing power to all components of a CCTV system in a centralized manner. It converts the electrical energy from the main power source into the correct voltage and current required by the CCTV cameras and other connected devices. This centralized approach allows for efficient power distribution, reducing the need for individual power sources for each camera or device, which simplifies installation and maintenance. A PSU usually features multiple outputs tailored to the specific power requirements of various devices, ensuring that all components receive the appropriate voltage. This helps maintain system reliability and performance, as consistent power is crucial for the optimal functioning of video surveillance technology. In contrast, the other options, while important to a CCTV system, do not serve the function of powering the system as a whole. The camera module captures video, the video storage unit stores the footage, and the network switch facilitates communication between devices but does not provide the power needed for operation.
