A business owner wishes to install an IP surveillance camera in a location that lacks electrical outlets. The network switch used in the office environment does not support PoE. What device should the owner use to supply both power and data connectivity to the camera using a single Ethernet cable?
A Power over Ethernet injector is used in scenarios where a device requires both power and data but the network switch in use doesn't support PoE. The injector adds power capabilities to the network line allowing the device to be powered over the same cable as the data, thus eliminating the need for a separate power source. A PoE splitter is incorrect because it performs the opposite function, separating the power and data signals at the receiving end. An Uninterruptable Power Supply (UPS) is used for power backup and cannot inject PoE into the cable. And a network switch with built-in PoE is not applicable because the scenario specified that the switch lacks PoE.
