A PoE injector is able to provide both power and data transmission over a single Ethernet cable.
1. PoE injectors operate according to the IEEE 802.3 standards:
(1)PoE (802.3af): One type of PoE injector can deliver up to 15.4W of power to each connected port, which is suitable for running devices that consume less power, such as ordinary webcams and Internet phones.
(2)PoE+ (802.3at): This type of product can deliver up to 30 watts of power to each port, which is enough to support devices that require more power to work, such as more complex security cameras or wireless access points.
(3)PoE++ (802.3bt): The current highest specification PoE++ can provide 60W or 100W power output for devices connected to a single network cable, which greatly expands the range of supported devices and is especially suitable for devices that require a lot of power during operation, such as high-energy consumption devices such as video conferencing systems.
2. Applications of POE Injectors
(1)Security and Surveillance: In security systems, PoE injectors power IP cameras, enabling high-definition video transmission over long distances without the need for additional power sources.
(2)Telecommunications: VoIP phones utilize PoE technology, simplifying installation and eliminating the clutter of multiple power cables.
(3)Wireless Networking: wireless networking devices can be installed in locations far from power sources, and only require network cables to complete power supply and networking, which makes network coverage in homes, offices or public areas more stable and reliable.
(4)Smart Buildings and IoT: In modern buildings, this power supply technology can also provide power for various sensor devices and lighting facilities, achieving energy saving through centralized management, while improving the convenience of automatic operation of equipment.
