The full name of PoE is: Power over Ethernet, which means that you use RJ45 cable to connect to this port, it will be able to power the connected device at the other end, often used for cameras (Network cable has 8 cores and only 4 cores are needed to transmit the network, the remaining 4 cores are used to transmit the following power source)
Power over Ethernet solution - PoE (Power Over Ethernet)
TCP / IP protocol on the Ethernet platform is very popular in today's communication market. The success of Ethernet-based technologies is in part due to the very active cooperation in the development of common standards. This success will also create new strengths on existing infrastructures such as cabling, network architecture, packet format and drivers that are already installed in existing Ethernet networks.
Powering through POE network is a specialized device to supply power via network cable, making it easier to go signal and network wires only by a single cable 5 cat network cable.
Powered by 802.3af standard POE network with high data transfer rate, the output of power supply device via poe provides 12V output voltage.
The POE power supply device is designed to protect against lightning, effectively protect and to reduce losses when equipment is struck by lightning.
POE network power technology creates a major turning point in technology with the introduction of many new types of devices and applications such as fully connected "smart buildings".
Power over Ethernet can overcome some location restrictions. For example, in repositioning the access point in the wireless LAN without concern about installing a new power outlet at the new location.on.
