Using DC12v Adapters on passive PoE injector Cables ok?

Recommended Posts

I have an IP CAMERA (several different models) with both PoE Support and DC 12v connector.

 

Using a regular 12v 2A DC Adapter directly connected to it works fine.

 

I wanted to make use of the PoE Support but i dont have PoE Power Supply

 

I do have

1. Passive PoE Injector Cables

2. regular 12v DC power adapters for CCTV equipment

 

Connecting the PoE injector to the PoE Port of the device using a straight through UTP cable, DOESn'T WORK.

If you connect a DC 12v power supply to the power end on your camera it should work.

If you want to send the power through the Cat5/6 cable instead(and the camera is PoE capable) then 48v power supply is normally used. 12v will not work through the Cat5/6 wires.

OK.

but i have also another dilema

 

1. If we use a voltage tester on the PoE Splitter side , not a single volt of power is detected

this is the case for both straight through and cross over crimping

 

2. if we connect the LAN cable direct to LAN port of camera , still no power (coz i assume the camera doesn't have BUILT IN poe support since it has connector cables for DC plug)
