YuanLey 4 Port PoE Extender Gigabit with 3 PoE Out, IEEE 802.3af/at Mini 4 Channel Repeater 1000Mbps, VLAN, Wall and Din Rail Mount Passthrough POE Amplifier/Booster, Plug and Play

Gigabit 4 Channel Passive PoE ExtenderThis 4 port gigabit PoE extender include 3 PoE out and 1 PoE in. It can provides PoE power to up to three PoE devices, 10/100/1000Mbps speed. Each PoE extender has an transmission distance of 330ft (100m).
IEEE 802.3 af and IEEE 802.3 atThis 3 channel PoE extender works with all standard IEEE 802.3 af/at POE switches, POE injectors and POE NVRs. PoE voltage is 44-57V. The Max input is 30W, and the Max output is 30W. Each port can power standard PoE devices like IP phones, IP security, IP speakers, etc.
VLAN and 3 Levels CascadeExtra 330ft (100m) PoE+ data transmission can be extended through a YuanLey PoE repeater. And it supports 3 levels cascade, therefore, it can achieve PoE data transmission up to 1312ft with 3 PoE extender. Out Ports 1 - 4 support VLAN isolation, preventing data leakage, and increase network security.
Unmanaged PoE RepeaterNo setup is required, no power, just need a network cable to expand PoE network, plug and play. Supports automatic detection of devices and powers compliant standard PDs.
Widely ApplicationCompact size ( 3.2 " *2" *1" ), supports wall mount and din-rail mount, can be installed anywhere as needed. You can connect AP, IP camera, IP phone etc..
