5 Pairs Passive PoE Injector and PoE Splitter Kit with 5.5x2.1 mm DC Connector RJ45 Power Over Ethernet

This is great for using Ethernet cable to move power and data on a single CAT-5 cable. Although I believe it's made mostly for security cameras due to connectors on the sending and receiving cables, I suppose it can be used for anything as long as the voltage doesn't exceed higher than 60v.A great use for me personally was to put a small 5 port Ethernet switch in a location that I had no access to an outlet. The voltage for the switch is 5v, but connector was different. Had to do some DIY to change the connector but when finished, I was able to power the switch and distribute the data to other devices.I should also note that this setup may be best used in 10Mb and not suitable for 100Mb or Gigabit networks, since the cabling uses 4 of available 8 wires in the CAT-5 cable for distributing power.

product is amazing when combined with shorter PoE cables, but it simply does not have the ability to carry such a current through 100 ft.update: you can definitely still use it, just make sure you use a good power supply. I needed 12 volts at 2 amps for 8 cams; about 24 watts a piece. I bought a 360 watt 12 volt 30 amp power supply and simply connected 2.1x5.5 lines to it. these adaptors work fine, even with the extra juice ( needed due to 100ft being too great)

Great value pack and excellent quality and performance.Need to power an Access Point, Camera, etc but no AC outlets are nearby ? this is the product you need. We had a unique situation where we had three (3) access points to install in locations where no AC power outlets were installed. This would not be a problem if the Access Points could be powered by POE but these units could only be powered by a 12VDC power adapter. These adapters allowed us to centrally power the APs while sending data and power over the same cable. All is well that ends well.

Needed to extend my cameras 30 feet. I used ethernet wire and was able to run long and inexpensive length for my cameras.

Great way to make non POE into POE

This was the best solution to POE switch.

Pair 1, Orange White, is flipped between the male and female connectors. It is consistent so if you are using their product on both ends, 10 Mb/s should function. This prevents a large number of devices from negotiating 100 Mb/s. Using for power injection to a POE device should work properly with or without their takeoff end installed.

These work well, but the listing never mentions that you will only get 10/100Mbs with these. They only use 2 of the pairs for the data, and put the power on the other 2 pairs of the ethernet cable.It''s nice that the power plug works perfectly for TP-Link Deco X55 Mesh wifi modules.
