On technical perspective, PoE technology has been developed for many years, now PoE technology is in mature stage.
Note: Currently, PoE technology has two standards - IEEE802.3af and IEEE802.3at. Powered Device (PD): IP/network cameras in video surveillance system. Power Sourcing Equipment (PSE): The equipment supports PoE function such as PoE switch, PoE injector (midspan) etc. PoE allows you to supply power to a networking device using the same cable that transmits the data, which in turn, greatly reduce the cost of installation and maintenance.Ī complete PoE system includes Power Sourcing Equipment (PSE) and Powered Device (PD) two parts. PoE stands for Power over Ethernet, it's a technology that transmits both data and power supply simultaneously to network devices (such as VoIP phones, Wireless AP, network camera etc) without changing existing Cat.5 cable network structure. In the exchange of technology, integrators and installers often feel confused on Power over Ethernet (PoE) problems, Tom feel the importance of PoE technology, herein, Tom invited a PoE expert to provide comprehensive information about PoE. Tom is a sales representative in video surveillance industry for several years, everyday exchanges ideas with security integrators. Since the rapid development of network video surveillance, technical barriers are getting higher and higher, manufacturers offer technical support is also becoming comprehensive and systematic.
