I use this. As long as your POE source can provide 30watt AND all your cameras uses less than 30watt, it'll work fine.

Ive bought one of these but not tried it as of yet. Sorry if this sounds stupid (Didn't know these existed but just what im looking for if it works)......So am i correct in thinking. I have one cat cable from my NVR's POE port connected to this splitter, 2 cameras feeding off the splitter. On the NVR itself. set the camera config as manual rather than plug and play and then enter the ip addresses of each camera? which will then use 2 of my 16 channels, even though only one port on the NVR itself is used?

In theory it should work with plug n play but you could try that.
I wasnt able to get it to work from an NVR PoE port so I bought a cheap little 5 port switch that sits beside the NVR and plug it into that, assigning each a static IP on my LAN

I tried this one today and can say that it doesn't work. All other cameras turn off and the connected ones don't work. Now I'm looking for an alternative. I want each port from the NVR to go into the extension and then connect to the three cameras with a cable.
The one you bought does not support PoE. There should be plenty that would work if you look here: Amazon.de : poe passthrough switch
Not everything in amazon search results will be compatible. You need specifically something that has PoE input and PoE output. It may say PoE extender or PoE repeater. You also need its maximum power limit to be enough for 3 cameras.

I want to use the Poe from my NVR. I need three inputs and one output. Then one input and three outputs for the cameras. I have now ordered them and will test them.

As has been mentioned, these ^^^^ are essentially POE-powered switches but retailers have an affinity for the term "POE repeater" and "POE extender."
Sorry for the question, but I haven't done this with an extender before. If I use port 5 to power three cameras, will one of them automatically connect to port 5 and will I have to set the others to the correct port myself?As has been mentioned, these ^^^^ are essentially POE-powered switches but retailers have an affinity for the term "POE repeater" and "POE extender."
I don't think an NVR POE port will work that way for you. Normally only one camera can be assigned per port and will only see one camera regardless of your configuration.
Your better bet is to connect the cameras to a POE switch and then that to the WAN/LAN of the NVR.

Negative.
As stated by @wittaj, connect cameras to POE switch on your LAN, assign unique, static IP's to the NVR's LAN and to each of the POE cameras, all in the same subnet but outside of the router's (if any) DHCP pool.
