Attention! Attention! Attention!: -This PoE Cable kit should work with External Power adapter(NOT inclued in this listing) to power on the device. -For 12V power supply included listing, Please check : B00YGLCQQK Passive PoE Injector and PoE Splitter Kit allows low cost of delivering power over the network cable for shorter distances. This kit allows power to be carried on 10/100 networks over the spare, unused pairs of a CAT5, CAT5E, CAT6 or CAT7 Ethernet network cable. On shorter network lengths, The power source could feed the wireless access point, IP video surveillance camera,Ip phone etc. This Kit contains both very cost effective injector and splitter. The injector inserts the DC voltage at the source location into the 5.5mm x 2.1mm injector plug, Then the DC voltage run through the spare pairs of the 10BASE-T or 100BASE-T network cable to the Splitter side, And the splitter splits the DC voltage from the network cable into the 5.5mm x 2.1mm DC jack. Power feed Pins: 4/5(+), 7/8(-) What in box? 2 x PoE injector cable; 2 x PoE splitter cable; FAQ: What external power adapter need? Condition 1: (You have a Original power adapter works with your Devices) -- Check and make sure the Size of DC plug is 2.1x5.5mm, -- If DC size is correct, Just use with your orignal power adapter as the wiring diagram Condition 2: (You don't have original power adapter for reference) --Please Buy external power supply which meet your devices. Please get following specs of your devices from Manual or Supplier 1. Input voltage should be 5~57V DC, Max 1.5amp 2, DC plug size should be 2.1x5.5mm
