For powering your PoE device via an Ethernet cable
A midspan enables an existing network to support PoE. The midspan, which adds power to an Ethernet cable, is placed between a network switch and powered devices. Midspans can vary from 1 and up to 48 ports that support the IEEE 802.3af/802.3at Type 1.
Midspans come in single and multi-port versions and are unmanaged. For managed multi-port PoE solutions please check the Axis network switches, specifically designed for security and surveillance use.
