What is a poe injector?

A PoE (Power over Ethernet) injector is a device that allows network cables to carry electrical power in addition to data. This eliminates the need for separate power sources for network devices, such as IP cameras, VoIP phones, and wireless access points, simplifying installation and reducing the number of cables needed.

PoE injectors typically have two ports: one for connecting to a power source, such as a wall outlet, and another for connecting to a network device. The injector supplies power to the device through the network cable, allowing it to operate without the need for a separate power adapter.

PoE injectors come in various power ratings, typically ranging from 15W to 90W, depending on the power requirements of the connected devices. Some injectors also support PoE standards such as IEEE 802.3af and IEEE 802.3at, which provide different power levels and capabilities.

Overall, PoE injectors are a convenient and cost-effective solution for powering network devices in locations where installing separate power sources is impractical or expensive.
