Passive PoE Injector and PoE Splitter Kit with 5.5x2.1 mm DC Connector

It's an easy way to inject DC and recover it at the other end.Speed test showed 100 Mbps at 2 feet, while carrying 2W or 20W.Speed test showed 10 Mbps at 250 feet (carrying 2W).Ethernet plugs have 4 conductors, as expected.

I really recommend this product.I think this comment will help many buyers because before I bought it I didn't have an answer to these questions.First of all, I should mention the quality, the plastic and the cable are quite high quality. It came packed in a special factory bag.I needed this product to power the IP camera.There is a 20% copper internet cable in the wall, which made me afraid of how much power it could carry. This product worked great.In my case, the power source is 12 volts 1 amp.With this method, both audio and lighting worked on the camera.

nice

I used this dc injector / receiver pair to power my ATT fiber to catX unit that was mounted in my crawl space. I simply removed the power adapter (not good in a damp crawl space - and the extension cord -ugg) and plugged this in. The power is now injected up in my garage where I have a modest little networking shelf setup. I can now power it all from a UPS and it’s super simple to reset/reboot everything as needed. My network speed has been capped at 50x50 by ATT and I believe that this dc balun set basically allows for 100mb connection since it halves the wiring to use for the DC power. Four of the eight wires are now used for power transfer and it would by definition disable the ability to get gig speeds. If I upgrade in the future I’ll simply run another cat5 or 6 line to gain gig speeds and keep this in place.

By the time I got to use them I found out that they did not work at all.Test them right away. Their QC is not very good. With that said I hope you don't get a fire.

I wanted something (T10/100 2 pair) that would carry voltage (normal passive on non data lines) between router and other end without fear of voltage on otherwise unused pins. In my case I was down converting 12v to 5 volt and running up to split back out into a ring base, so unsure what stray 5 volts might do on non data lines … well this was 100% bullet proof (plug in or out only have 4 of 8 wires) No not gigabyte compatible but if your device will accept 100 negotiation you won’t mess expensive things up assuming (just not there so safe)Single wire ring base remotely installed, no 110v nearby needed. Runs for months on battery backup (if ever needed) so a win-win (batteries not included. Size matters ;-)

I am using this to power a Apple Extreme Gen 4 over a 150 foot Cat-6 cable in order to power the hub to provide wifi and internet connection for a dropcam 720p camera for my driveway.Was concerned that it would not extend power, but it sufficently powers. However, I had to get adaptors to make the ends fit.Bought:Coax Barrel Plug Adapter from 2.5mm to 2.1mm Power PlugSold by: Creative Lightings$2.205.5mm x 2.5mm Male Plug to 5.5mm x 2.1mm Female Jack DC Power AdapterSold by: uxcell Product question? Ask Seller$2.83Now I am looking to see if I can get a USB splitter to help get power to the dropcam in addition.Going to call WiFi-Texas tomorrow to see if that is a way of adapting. If not, I will use a battery backup to power, as there is only power in the evening via light socket to 120v adaptor. Dont really want to run a power cable.Open to any other suggestions.

The kit only use two pairs of wire (Orange 1/2 and Green 3/6) which is great in case your PoE switch power output can not be shutdown. Inner contact uses both Blue (4/5) pair of wires and outer contact uses both Brown (7/8) pair. Made a couple of tests and got good results. Would it be nice to have that info first hand, but other than that this looks like a good product. Just a reminder that DC voltage is affected by distance unlike AC voltage; test the voltage drop before deploy.However I was not able to deploy them on the project due to delivery issues (Amazon/USPS: when a package says “Delivered” it means delivered not “Scanned as Delivered one day and actually Delivered a couple of days later”).
