I want to install 2 dahua POE cameras in fairly remote locations and wiring is a problem to these locations except they currently have mains 240v. don't want to use wifi etc so powerline adaptors which also provide POE would be ideal such as these...



unfortunately, the cameras require 12v dc over POE and these devices don't work on 12v. does anyone know of a similar 12v device?
 
You can use a PoE splitter near the camera end to convert the 48v af/at power to 12v. You will probably need an enclosure for it to go in though.
 
You can get POE injectors if you have sockets nearby.
Ethernet goes into POE injector and out the other end into POE Camera. Cost about £10-15

i could use one of these but i wondered if there was a single box?

Yup, something like https://www.amazon.co.uk/dp/B08HS4NT13/ or https://www.amazon.co.uk/dp/B07TML96C9/
but they would require "proper" PoE (802.3af or at).

You might find it easier to keep the powerline and the PoE bits seperate as you're possibly paying slightly more for having it combined in one box, it would also be easier to replace bits if there's a a fault.

Cheaper injectors/splitters just put a voltage on a pair and use two pairs for 100M ethernet which may also be fine for your install.

thanks for your assistance but it looks like I'd need 3 boxes altogether using either of those items?
 
This:

Ethernet cable goes into one side of it and power cable goes into the other side. Then ethernet cable out of that into your POE camera.

so how many boxes required for that solution? sounds like 2+

to be clear: the original post shows a single box which plugs into the 240v mains and has only one socket on it which is a POE enabled ethernet port. unfortunately, on the original device it doesn't provide 12v which my cameras require.

Surely this is where the confusion starts! I have never heard of a 12V POE standard!!
Please can you identify the camera model number ?
I am sure if you read the specification it is 12Vdc OR POE, meaning it can be powered by by a 12Vdc source OR POE. POE is normally nominally 48Vdc, nothing to do with 12V whatever.
