I don't seem to find any information about which sort of video adapter I need if I want to connect a video camera (round, 4-pin plug, similar to localtalk) to my Mac Pro with Nvidia Geforce 7300. Can anybody enlighten me please?

The Mac Pro doesn't have a video input. It sounds like you're describing an S-Video connector. You can buy an S-Video to firewire converter for under $ 200, but there's no way to connect S-video directly to your Mac without additional hardware.
