BV-Tech 4 Port PoE+ Switch with 2 Ethernet Uplink and Extend Function 60W 802.3at + 1 High Power PoE Port

work great

No issues, works exactly as I expected.

I bought this for the PoE+ feature to be able to power other PoE device downstream. No issues. I like that it has a second uplink port .

The throughput is smooth and balanced.. It is as good as "name brand units" at 1/3 of the cost. I am an integrator and have used multiple POE+, POE and switches in harsh environments. This is a deal!!

I looked at many PoE injectors, and decided for $34 this is the best option. I initially purchased just one PoE camera, but this switch allows me to add three more by simply running the ethernet cable. What more could you ask for? This switch has a PoE+ port on the first plug, and all four plugs will run at PoE standard power levels. If you need PoE+ you probably cannot use all four, it will limit you to one or two more standard PoE plugs, because it has a maximum power output. There is a switch for Default, and Extended. If you need to run longer than 300 feet you can switch to extended, it will reduce the bandwidth of the PoE ports to 10Mbps, and increase the power, so that it can run longer cables safely. I don't recommend this, just try to use the 300 feet limit, and the default setting and you will be fine. If you have to go longer, I suggest you but another of these, or an individual injector. Then, use 300 feet cable segments with switch/hubs to reach you destination at full speed. My house is all 1000Mbps ethernet. I connect the PoE switch to one of the ports and it runs at 100Mbps with the switch. There are two uplink ports on the switch, not sure why you need it, but you could connect two networks to this, if you so desired. If you are buying a single camera, I suggest skipping the single PoE injectors and getting this. You then have the option of adding three more cameras without needing another injector. The 100Mbps is more than enough bandwidth for the cameras, they usually need about 2Mbps each. Most single injectors are $19. This is $34 and gives you 4 standard PoE injectors with one optionally running PoE+. This is a great deal, and a good choice. Be smart and plan ahead, that is what I did. I just ordered additional cameras today, and I am very glad I purchased this, because I don't need to get more injectors, just need the camera and ethernet cables to hook it up.
