Which of the following can be an application for Power over Ethernet (PoE)?

The correct answer encompasses a variety of applications that can utilize Power over Ethernet (PoE) technology. PoE allows data and electrical power to be transmitted simultaneously over standard Ethernet cables, which enables devices to operate without the need for separate power supplies.

CCTV systems benefit from PoE as it simplifies installation by eliminating the need for additional electrical outlets near the cameras. This is particularly valuable in remote locations where running electrical wiring can be complex or costly.

Lighting systems are increasingly being designed to leverage PoE technology, as it enables smart lighting solutions that can be controlled remotely, providing energy efficiency and reducing installation complexity.

WiFi access points are also a common application for PoE. By using PoE, these devices can be placed in optimal locations for coverage without worrying about proximity to power sources, enhancing network performance and accessibility.

Thus, the ability of PoE to support CCTV, lighting, and WiFi access points demonstrates its versatility and widespread utility in modern electronic systems, making the option that includes all these applications the most comprehensive and accurate choice.
