A Poe injector takes a standard PoE (power over ethernet) cable and inserts power into the cable. It works by connecting the DC power supply to the injector, and then connecting the injector to the Ethernet cable. This transmits power down the Ethernet cable which is then accessed at the other end. This process allows a device, such as a router or security camera, to be powered with no direct power connection.
A Poe injector works by taking the power on a network cable (typically a Cat 5 or Cat 6) and converting it into direct current (DC) power. This DC power is then used to power devices that require low-voltage DC power such as IP cameras, VoIP phones, or wireless access points. The Poe injector injects the DC power into the network cable and the device on the other end is able to draw the power from the cable, eliminating the need for a dedicated power cable.
