What is the role of a power supply in CCTV systems?

The role of a power supply in CCTV systems is fundamentally about delivering the necessary electrical power to cameras and associated equipment. CCTV systems require a reliable and stable power source to function properly, as any interruption in power can lead to loss of video feed, camera malfunction, or even complete system failure.

Cameras, digital video recorders (DVRs), and other components in a CCTV system operate on electrical power, and the specifications of the power supply must match these requirements to ensure optimal performance. A dedicated power supply ensures that all components receive the appropriate voltage and current, which is critical for maintaining the quality and integrity of the video surveillance being captured and transmitted.

While enhancing video data processing, enabling wireless signals, and controlling video compression settings are important functions in certain contexts, these tasks are not the primary function of the power supply itself. The power supply serves as the backbone that supports all operational aspects of the CCTV system by maintaining power flow.
