What is a major benefit of using Power over Ethernet (PoE) networks in CCTV?

The major benefit of using Power over Ethernet (PoE) networks in CCTV systems is that they eliminate the need for external power to the cameras. This technology allows both data and electrical power to be delivered through a single Ethernet cable, simplifying installation and reducing the infrastructure needed for a surveillance system.

By utilizing PoE, CCTV cameras can be installed in locations that may not have easy access to electrical outlets, which can enhance flexibility in positioning the cameras for optimal coverage. This innovative approach not only streamlines the setup by decreasing the number of cables required but also simplifies maintenance, as there are fewer points of failure.

While access to videos, reduced cabling, and image resolution are important aspects of CCTV systems, the primary distinction of PoE is its capability to provide power directly through the network cable, thus addressing the power supply issue for remote devices.
