What is a CCTV system's power over Ethernet (PoE) capability?

A CCTV system's Power over Ethernet (PoE) capability enables network cables to deliver electrical power to connected devices, such as cameras, using the same cable that transmits data. This integrated approach simplifies installation by reducing the need for separate power sources and outlets for each device, making it especially valuable in settings where power accessibility is limited.

With PoE, the installation process becomes more streamlined, as it enables both data and power transmission over standard Ethernet cables. This dual functionality not only saves costs by minimizing additional wiring and equipment but also allows for greater flexibility in camera placement, as cameras can be installed in locations further away from traditional power sources.

The other choices refer to different aspects of CCTV technology, such as wireless operations or video quality enhancements, which do not directly relate to the core functionality of PoE.
