The following set up shows how a network camera can receive power over a network cable and can continue to function even when there is a power failure.

Axis offers two types of accessories that enable Axis network video products to receive power and data over an Ethernet connection:

Power over LAN Midspan

The Power over LAN Midspan is connected in between the switch/hub and the Power over Ethernet-enabled products. It uses the unused pairs in a standard Cat 5 network cable to supply power to Power over Ethernet-enabled products that are up to 328 feet (100 meters) away.

An important feature is autodetection of Power over Ethernet-enabled (PoE) products, such as the AXIS 211 Network Camera, AXIS 211A Network Camera and AXIS 221 Day & Night Network Camera. This means that power will only be delivered to products designed to accept power over the network and not to standard networked equipment such as desktop computer and laptops.

The Power over LAN Midspan can be connected to a UPS (uninterrupted power supply) device, which enables PoE-enabled devices, as well as non-PoE devices that use a Power over LAN Active Splitter, to continue to operate even when there is a power failure. 

Power over Ethernet AF Active Splitter or Power over LAN Active Splitter

An active splitter gives the Axis network video products that lack built-in support for Power over Ethernet, the ability to receive power over the network by splitting the data and power coming over the network cable. (With products such as the AXIS 211, which has built-in Power over Ethernet, an active splitter is not required.)

Notes:

• The Power over LAN Active Splitter works only with the Power over LAN Midspan, which is connected to a standard switch/hub. The Power over LAN Active Splitter is not compatible with Power over Ethernet-enabled switches.

• The Power over Ethernet AF Active Splitter is IEEE 802.3af compliant and can be used with the PoL Midspan or a PoE-enabled switch.
