It can be used to transmit ip over coax...you need one on both ends..

Cheers.

Bit confusing though as this data sheet says the device is for an ip camera. How would that work? :shame:

Yes, you use one on both ends...its simply allows ip over two wire connections like coax...

If I've understood your query correctly (if not, apologies):
For 10/100Mbps Ethernet transmission just 2 of the 4 pairs are used - but over the single wire coax the signals are modulated on to multiple carriers.
Think of a TV signal over coax - how many channels can it transmit, when each is modulated over a carrier at a slightly different frequency than the others, so you can tune each in selectively.
Ethernet signals over UTP Unshielded Twisted Pair cable are not modulated on to separate carriers.
