Thanks for the suggestions Mike, unfortunately I already have the camera and need to make it work somehow.
Good news is after many hours I have found a combination that works, amazingly.....
To get it working this is what I have had to do, it's messy but it works.
From a 802.3af POE switch I run one cable from a POE port to port 1 of an Ethernet splitter (2>1) then run another cable from a normal Ethernet port on the switch to port 2 of the splitter. On the other side of the splitter where there is just the single cable I
that into a Mikrotik Gigabit POE injector, I also plug 24V power into that injector. I then run the single cable as long as I needed to, so far only in the office but the run isn't very long at the site. At the other end of the cable I place another Ethernet splitter (1>2), however before I go into the splitter I placed another Gigabit POE injector but around the wrong way, so POE+Data side facing the other injector at
head end, then in port 1 of that splitter I run a cable straight to the 802.3af POE camera and it powers up by using the POE from the switch over the data pairs, I had to use the right port on the splitter, only the one which transported the original 1,2,3,6 cables worked, this was port 1 in my case. Then port 2 runs to another Gigabit POE injector with the POE+Data heading away from the splitter to the Mikrotik QRT. From the second POE injector, just before the second splitter, I take
LOL Mike, yes, but the second cable I couldn't do and would have cost another $5k as it's an extremely complex run and at height so running an extra cable just wasn't an option unless I had a total fail in making this work.

That is totally amazing :-o I am slackjawed just hearing that anyone would attempt such a configuration! :-D Nice work - though 'after many hours'... really - it would have taken 'many hours' to run a second cable? ;) Cheers! Mike. plug the power
from that and then feed it into the 3rd POE injector which ultimately goes to the QRT.
I know this is a long way around to get the result but I simply had to work with what I had and what I could get to work.
Anyway, it works and will save my butt tomorrow :-)
I hope it helps somebody else anyway.
Regards Paul

Hi!
Have you selected the camera yet? If not, I am sure there are a few camera models available on the market that have poe-passthrough, in which case you can just choose one that either: Supports passive PoE, then hook it up using the same cable and injector that is in place, or Supports 802.3af, then power the cam with 48v power supply (or Poe Switch) and use 802.3af converter for the QRT
Cheers!
Mike.

Hi guys, we have a Mikroitk QRT on a mast running from a POE injector down below in the building, it's all working fine. We now need to add an IP camera on the mast which will use the same cable and needs to run from POE as well. The QRT only has one port and we need that radio, an omnitik with poe out won't work, so we need to split the cable somehow with a hardened switch or something, but the catch is that the Mikrotik passive POE won't run the camera as it's 802.3af, I am looking for some quick to implement and relatively cheap ways of making this happen and was hoping somebody would have some simple suggestions ?
There is no option to run a second cable so I have to make this work somehow with one cable L
