The PoE Extneder does not require local power and is powered via the PoE input.

Support the IEEE 802.3af/802.3at the Power over Ethernet PoE Switch
Support DC48V~57V Passive Power Over Ethernet PoE Switch
Support DC48V~57V Passive Power Over Ethernet PoE injector

The PoE Extender has 3 10/100M PoE ports, among them, 1 port for POE input, and 2 ports for POE output. All ports Comply with 10/100BASE-TX, IEEE802.3at/IEEE802.3af . The power input is 30W in total. 2 ports POE output for total is 25W ( max).

PoE Extenders can increase the transmission distance up 100m via Cat5 UTP cables. It offers you great flexibility to extend the distance of PoE.

Only for use as a POE Extender Repeater:
When used with an 802.3at PoE switch, a maximum of three POE extenders can be cascaded. The maximum length is 400 meters (approximately 7 watts at the far end). It is recommended to use with an 802.3at PoE switch. Using an 802.3af PoE switch may result in insufficient power for the network cameras.
