D-Link 10/100 Power over Ethernet Splitter 5V/12V (DWL-P50)

I have this DWL-P50 powering a DWL-2100AP, splitting power from a gigabit link to which power has been injected by a TrendNet TPE-111GI.To anyone who is concerned about link speed:There are two injectors (one at either end), and another splitter (TrendNet TPE-112GS) to power a TrendNet switch. The injectors and the other splitter specifically claim "gigabit" speeds. D-Link does NOT claim the DWL-P50 to be capable of gigabit speeds, although I assume this is because the devices it's meant to power do not have gigabit interfaces (therefore, whats the point for D-Link to claim "gigabit" speed?).So I was a bit worried that this device would drop the speed of the link down significantly. Although I lost a couple of megabytes per second off my average throughput, I've still got something like 95% of it, which is totally acceptable.I've used CAT7 cables exclusively throughout the installation, so cabling cannot be the culprit, with one exception. Unlike the DWL-P50, the TPE-112GS has a captive Ethernet cable, which is from my perspective a TERRIBLE idea. I suspect that one or more of these PoE devices (injectors, splitters) is responsible for the bulk of the loss of throughput. I must admit...I noticed the biggest loss of throughput after installing the DWL-P50. But to be fair, it seems the other PoE devices also contributed to the overall loss of throughput.Just to make sure, I also added some ferrite cores to the power cabling throughout the install, just to eliminate a possible cause. It didn't seem to help.Ultimately, the DWL-P50 IS operating at gigabit speeds for me. The link is running at 98MB/sec average compared to 103MB/sec avg with the other PoE injectors splitters, and 107MB/sec avg without any PoE hardware on the link. Considering the other options are to run a dedicated line just for the DWL-2100AP, or to lose the DWL-2100AP when the power is out, or to install a dedicated UPS just for the switch and AP, I think the convenience and simplicity is worth the slight (mostly insignificant) decrease in speed.Bottom line....The DWL-P50 is gigabit capable!

I've had 5 of these make a popping noise, put out a bit of smoke, and eject some electrolyte (presumably all from a popping capacitor). However, after these episodes, they've all worked just fine. I'm using the 12 V setting, no idea how it'll work for 5 V.They were popping when connected to a Netgear fs108p switch. After manually adding ground to the switch, no more of these babies have popped. Kinda miss it, to be honest... but it's nice not to have to worry about the sprinklers going off.

I tried to use this for my security cameras. I was thinking that it would inject the power over the Ethernet cable so that I could have one Ethernet cable go to the security camera.It turns out that you have to plug this adapter into the Camera power jack in addition to the Ethernet cable. . . rather than input the power at the switch, and run a single cable to the camera. The power cable provided from the adapter to your camera isn't that long either, so I didn't even bother to plug and test the adapter.They should've added this fact to the description of the product.

I'm with the other reviewer, this is not a standard POE injector, it is designed to work with D-Link equipment it seems, the description needs to be better. I gave it 3 stars because I don't know how well it would work if I could use it. It does *not* come with a AC adapter, it assumes there is power on the ethernet and breaks it back down into just enet and just power -- it's the OPPOSITE of a power injector. Anyway, maybe I'm wrong, I messed with it for 5 minutes and then a glance at the manual made it seem like a lost cause so back to the jungle it goes!

The description for this items suggests that it works independently to provide POE, but that isn't the case. It requires a compatible D-Link switch. I can't vouch for the functionality of this item because it wouldn't work with my existing network equipment, so I had to send it back for a refund.

Spares having to supply separate power to remotely placed Ethernet devices, and reduces network clutter and the number of those annoying "wall wart" transformers that are the plague of electronics these days. Great for placing Web cams in out-of-the-way places where you are not likely to have 120VAC outlets.

Using this to split power back out to my IP Cams from a POE switch. Its great when you dont have power near your camera's, and your camera dont natively support POE. Small and easy to hide.

Great product
