Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points (WAPs), IP cameras and VoIP phones .
The IEEE 1901 Standard was a significant step in the development of powerline communication (PLC) technologies. PLC allows for data communication over existing power lines, which can be particularly useful in environments where it's difficult to lay new wiring or where wireless communication might be problematic.
GigE Vision [1] is an interface standard introduced in 2006 for high-performance industrial cameras. It provides a framework for transmitting high-speed video and related control data over Ethernet networks.
The first Ethernet standard, known as 10BASE5 (ThickNet) in the family of IEEE 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10BASE2 (ThinNet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market.
The spare pairs may be used for power over Ethernet (PoE), for two plain old telephone service (POTS) lines, or for a second 10BASE-T or 100BASE-TX connection. In practice, great care must be taken to separate these pairs as 10/100-Mbit/s Ethernet equipment electrically terminates the unused pins ("Bob Smith Termination"). [ 19 ]
The first centralized IP camera, the AXIS Neteye 200, was released in 1996 by Axis Communications. [3] Although the product was advertised to be accessible from anywhere with an internet connection, [4] the camera was not capable of streaming real-time video, and was limited to returning a single image for each request in the Common Intermediate Format (CIF).
