YuanLey 4 Port PoE Extender with 3 PoE Out, IEEE 802.3af/at Mini 4 Channel PoE Repeater 100Mbps, Wall and Din Rail Mount Passthrough POE Switch/Booster, Plug and Play

Great extender, works well, I have used cheaper but the failed over time, 3 years or more and goinf stng.

*EDIT*They seem to have read my previous review, as this device is now offered with up to 5 ports at 1000 MBPS speed. I had resorted to daisy chaining two of the 100 MBPS 4 port devices, and I replaced them with a single 5 port 1000 MBPS device. This was mostly just to save space, as the daisy chained devices were running four POE cameras between them just fine. One 5 port 1000 MBPS device and four POE cameras are combining to use 12 watts of power from the single switch port that is supplying POE to all of them.*ORIGINAL*I purchased this to replace an unmanaged POE switch to which I had three POE cameras connected. This is powered by POE output from my primary switch, which is about 150 feet away. This device and the three cameras combine to use about 10w of POE, well below what the primary switch is capable of. This device provides plenty of power for all three cameras, and provides plenty of bandwidth for them at 100 MBPS (which I was a little concerned about at first, as I would have preferred 1 GBPS uplink to be safe). And it takes up less than half the space the old switch did, it does not need a separate power source (being POE powered), and it costs less than half what the previous switch originally cost me. Other than losing room for expansion (which I could easily regain by daisy chaining another of these), this has turned out to be a significantly better option for me than a second standard POE switch. If you have a POE switch and want to split a single cable run off of it into three separate runs complete with POE, this is a device built to do that for you.

These little things are amazing for what they cost. One run from my POE switch, easily add a camera when I didn't think to run extra feeds of wire.

Works amazing had to add 4 camera at a post about 200ft away, had one of CAT-6 in the pipe and added a POE + injector just to make sure there is enough power going to the switch. A job that would of taken me about 2 days I was able to complete it in one.

I wanted this to power two smart-home hubs from central PoE switch that has back-up power so that I had more flexibility on placement of the hubs. For that I needed to also buy two PoE splitters. This is where I found compatibility issues as this did not work with the first set of splitters I bought. However, I returned them and bought two splitters from the same manufacturer, YuanLey, figuring that would work and it did. I also tested by connecting some devices I had that had PoE built in and they worked fine. The only downside left is that this is only a 100Mbps splitter, but for my use case this is perfectly fine.

Really handy way to add more PoE ports to an existing spot

Allowed me to add more poe cameras without pulling more Ethernet lines. Great. Has been running without issues for a year.

Very easy to install
