POE Combiner Splitter Adapter, Run 2 IP Cameras on 1 Cable, Works on All POE Switches, POE NVR and POE Cameras, Mode A and B POE Compatible

This does eactly what it says it will do and worked without touching the POE type switch while using it on a Ubiquiti poe device. It's not great with pre-terminated cables if you want to use the "waterproof" connectors. I would not consider them capable of keeping water out but this will definitely help you run two cameras as 10/100 with a single POE cable (of course you'll use up two poe ports on your switch). Would recommend if you can't run a dedicated ethernet line and need two devices that don't need gigabit.

Setting up the Reolink PoE Camera's with the Reolink NVR was straightforward and hassle-free. So far, the connection has been stable with no interruptions. I’m curious to see how well it performs over time.

Like many reviewers I did not expect this device to work but it does. For the price, you have to give it a try. Always better to connect each camera directly to the DVR to set up, and confirm you PoE mode.

It works, but I would have changed a few things... thing 1, the waterproof connectors are junk. I've done plenty of outdoor POE camera installs and there are connectors that work, and connectors that don't. These don't. I always use dielectric grease in the plugs to help with moisture resistance and even though I did that, I had this unit out for one day. One day! And rain came, water got in, and some of the cheap contacts in there rusted out. Probably shorted the POE if I had to guess (no damage to the switch though, a good POE switch knows when that happens and cuts off power).Thing 2, rather than having RJ-45 sockets on the output side, I would have preferred RJ-45 plugs. That's just me, so maybe there should be an option. As it is, for my install I had two cameras right there on a pole, basically facing forward and backward. So to use this, I had to grab a couple short cables to stick in between which just means even more watertight connectors to deal with, etc.When I had my water ingress and rusted pin, I just got done snipping off that particular socket (I think it was camera 1). I tested which color wires went to which pins so I could just wire it up to a new RJ-45 plug, which is currently working okay, and now I've avoided one extra ethernet cable on my setup. However, there's precious little slack on those wires where it splits out, so there's no way I could get a waterproof connector on. I'll have to stick with electrical tape and the aforementioned dielectric grease. Plus it helps to position the connection in a way that gravity will not let water pool into the socket itself.For anyone else who might need to rewire this... I didn't cut off the pigtail going to the 2nd camera, but at least on the first one (and you know which one is #1 because it's using pins 1,2,3 and 6 ... the other one uses 4,5,7,8), the wire colors are: #1 = white, #2 = yellow, #3 = black, and #6 = red. Wire those to an RJ-45 plug and you can do it too.Bear in mind, these wires in there are kind of cheap stranded wires, so good luck pushing it into your RJ-45. I tried and tried... eventually I had to strip back just a little bit of the wire itself and tin it with fresh solder, and that lets you push it into the plug and crimp it. It's also a pain in the neck to wire when you're only dealing with 4... pushing in all 8 wires is pretty easy because you just line them up and go. With 4, and using 1,2,3,6, it's kind of tricky to get it just right, so it takes some time and patience.Now, I figure I could have returned this since it's literally 2 days old and already rusted and broken, but I can't say for sure if the water issue was my fault or the crummy waterproof connector, so I sucked it up and fixed it on my own.For all the other connections, I made sure to use generous electrical tape now on all those joints. I figure water just got in past the rubber grommet where the wire goes in, because it's not really that tight, so taping it there to prevent water from getting there in the first place helps. I've done that in other spots where the connector seemed dubious. Time will tell if it all holds.

This splitter is what I've needed for years. It saved me from running another 100' of cat 6e cable. At first I didn't have much hope it would work until I found out that the one I was trying was defective. I returned it, and Amazon promptly sent a replacement next day. Well, I have been testing it for 3 months in house, until I add it to the security load. Works great, and I bought 3 more. Great price too. Can be used in the elements, or hidden under the eves.

I bought two splitters and both did not work. Only one side of the splitter worked as I switched the cameras feeds but one side was dead on both splitters. Amazon offered to send me two replacements but I just don't trust the manufacturer at all. Just don't waste your time with this item.

Works very well.

I bought one about six months ago after researching. Then bought a few more! Was a little unsure with the first one if it would work initially, given the power draw by two devices. But it has a switch for two types of wiring, good just in case! And I used the higher power PoE+ switch that was 802.3AT compliant. PoE switches that are only 802.3AF compliant don't put out nearly as much power on the line. So make sure your PoE switch is 802.3AF (PoE+) compliant. May work with one that's only 802.3AT, but I wouldn't try it to find out unless you already had one there. The better PoE+ switches aren't expensive.I had a PoE wired Ring cam, but wanted to add a Reolink PTZ camera about 15ft from the Ring cam that was also wired PoE without running an entire new cable. Easy to install, and both devices powered up and connected without any issues. Still running without a glitch 4 months later. So if you were going to use it to connect say two Ring or similar PoE cameras, it would have no problem with it as I'm fairly sure the Reolink PTZ cam pulls more power than the Ring cam with it's auto tracking.I wouldn't experiment with cheaper PoE splitters. This one is well engineered and won't let you down.
