Tech Gigabit Power Over Ethernet PoE+ Injector (30W POE+ Injector) | Plug & Play Setup, 325 ft Transmission, Auto Detection, IEEE 802.3 Compliant, Single Ethernet Cable

So far so good. The product was easy to setup and there hasn’t been any connectivity issues.

This worked perfectly. I needed POE for 3 ethernet connections. I started with a network switch but it would only supply power to 2 of the 3 lines. I bought 3 of these units and I couldn't be happier with the results.

Works as it should!

This is the third one I've bought in about ten years. Good product, but it will wear out after a few years. I bought this item at the request of the camera manufacturer that I use it with. I have 6 POE cameras, two of which exceed the limits of the NVR and need power injected into the cable. The telltale when it goes bad is that it starts a high pitched whine. Overall, I'm pleased with the unit, I just wish it lasted a bit longer. Currently, I've replaced one every 3 or 4 years.

They worked for the Unified AP. No issues.

I now have two of these that I use to power a Foscam outdoor IP camera, and a Ruckus wireless access point. I have a small 8 port switch with 4 PoE ports, but the switch can only supply a total of 30W, which limits me to two Foscam cameras. Since I discovered that, I now prefer to use these individual PoE injectors--it's easier to add new PoE devices with them vs. buying a much larger and more expensive PoE switch. The PoE injector is as simple as a basic power supply--just plug it in, and it works. The power cord is a thick 3-prong cord just like a standard PC power supply cable, so it isn't something you can easily hide. And the PoE Injector itself is larger than a typical 'brick' style AC power adapter, so you will need some place to stow or hang it. There are screw mounts on the back of the injector, so I was able to hang them up on the wall out of the way. And the sides of the injector have a plastic 'tongue and groove' on them, so you can slide several of them together to make one big block, which is handy. The device works great and has powered my smaller PoE devices just fine.

My review is based only on my situation, and it probably has nothing to do with the actual capability and performance of the PoE in the operation that it was intended. However, it did not work as I had hoped. I am not familiar with PoEs in general and had to search information on my existing one that I am using to power and antenna for fixed wireless on my roof. I have attached a picture of the existing PoE that I had intended to replace. Now, with all of that in mind, I couldn't really find the info I needed, so I had to extrapolate what I could find and apply it to the PoEs I could find. Obviously, my extrapolation was woefully deficient. So I am going to ask those of you who are familiar with these devices, what product could replace the PoE I have, based on the picture I have posted here with my review. I asked a question in the question section above, but I did not provide enough information in it to get an adequate answer, so I'm hoping I can get a comment that will help me in my search of a POE sufficient for replacing my current one. I have already bought three, and this is the first midspan of them, so I thought it would work. Thanks so much and I hope this might help someone who's in my situation who doesn't really know much about PoEs and is looking to replace one for a fixed wireless radio on their roof.

Good quality for the price. Never have any issues with these. The 60W was much cheaper than alternatives, but we've had zero issues with any of these.

Dopo poco più di un mese di funzionamento direi che l'articolo funziona bene. Lo utilizzo per alimentare una telecamera IP. Installazione semplice in cascata ad un wifi-extender Netgear. Consigliato

Just plug and play

Does what I need, to connect a VoiP when I work from home. Will update this if I need to in the future.

Utiliser pour alimenter mes caméra de surveillance, fonctionne comme décris....

Does exactly what it should, time will tell about reliability.
