    Tips: How does a PoE injector work?

    A Power over Ethernet (PoE) injector is a device used to deliver electrical power and network connectivity to devices over a single Ethernet cable. It enables the transmission of both data and power to compatible devices, eliminating the need for separate power cables.

    Here's how a PoE injector typically works:

    • Power Source: The PoE injector requires a power source, usually a standard electrical outlet. It is connected to the power source using a power cord.
    • Data Source: The injector also needs a data source, which is typically an Ethernet switch or a network router. The data source is connected to the injector via an Ethernet cable.
    • Power and Data Transmission: The PoE injector combines power and data signals. It takes the power from the electrical outlet and converts it to a form suitable for transmission over Ethernet cables. The data signals from the network source are also combined with the power signals.
    • Injection: The combined power and data signals are injected into an Ethernet cable. This cable is then connected to the device that requires both power and network connectivity. The device should be compatible with PoE and have a corresponding PoE port.
