Poe splitter not working for tplink

[vsauce]

The cameras are connect to tplink NVR. I have got 8 cameras C420I. And 4 pieces of C440W. The C440W cameras aren't working in Poe mode. They only work when connected with the DC power supply. They don't load in the NVR without DC power supply as well.
I bought few Poe splitter but they aren't doing anything.
Switches: Tplink TL-SF1009P
Camera: Tplink VIGI C440W
NVR: VIGI NVR R1016H 16 CHANNEL
On contacting tplink support, they confirmed these C440W cameras do not support POE power. But I need to fix the poe splitter issue.

There was a recent report of these passive cable splitters not working with an NVR, raising the question if the NVR uses mode B POE, where they wouldn't work. I've got no answer, just connecting dots.

Camera: Tplink VIGI C440W

This camera is not POE, DC pwr only.

This camera is not POE, DC pwr only.

Yes. But shouldn't a POE splitter be able to give proper power and Ethernet separately?

Yes. But shouldn't a POE splitter be able to give proper power and Ethernet separately?

Yes, but only if each camera and the NVR's LAN is configured with a unique, static IP, all in the same subnet but outside of the router's DHCP pool (if there is a router) then connected to the NVR's LAN via a switch, not plugged into any NVR POE port.

Insure the Ethernet cable has all 4 pairs, is wired either T-568B or T-568A on both ends and is pure copper, not CCA (Copper Clad Aluminum).

Yes. The NVR and the cameras are in the same subnet pool. The router to connected to one of the switch.
The rest of the plain poe cameras are working but the ones with the splitter are not working.

Have you confirmed that the camera works when connected without the splitter?

If so, then the problem is with the power feed, data line, or both.
You can first verify that the camera is getting power.
If that's ok, you can run a separate data wire between the camera and switch to see if that makes it work.
First identify where the problem is, then work on fixing it.
Most likely it's a single point failure, either the power feed doesn't work, or the data line doesn't work. Multiple failures can be maddening to debug.

The picture on the amazon link makes the splitter look suspicious. The wire colors on the RJ45s are all wrong. That in itself isn't proof of defective because they could use a different color convention internally in the splitter. It's just that one wire being brown looks kind of suspicious.

Thanks for going so indepth.
Yes the cameras work with separate DC and POE. Also IRL the splitter has two 3 wire colours red,black and green. Don't see any brown wire in it.
I can confirm the camera works entirely correctly without the splitter. Without the splitter it is connected with DC power supply and LAN Ethernet port. This works fine. But the splitter doesn't work at all. I tried few other splitters as well, and same problem.

Probably

The RJ45 needs 4 wires connected to work, pins 1, 2, 3, and 6.

Did you try the splitter with a short piece of network cable? I have tried this sort of splitter as well on a non-poe camera and if i remember correct it had issues because of the network cable length. Maybe the powersupply isn't powerful enough?

For the record:

Sorry for late reply.
Yes. The network cable is fine and the distance between switch and camera is just 4 meters.
Can confirm the entire system is running on T568-B Ethernet cable.
The manual says the switch supports upto 30W in each poe port. And the camera needs just 12W. Still it doesn't works.
I tested out other such splitter but it's all the same.
Any other options? I really need to make the cameras work without DC.

If both ends (splitter end and injector end) don't comply with what is stated in my post #12, it won't work.
