The How is a matter of how your PC is setup. I don't see any reason it can't be done, I have done it. The only issue is the mating connectors. Some PCs have a motherboard with integrated audio and video while some use individual cards. All should have audio and video inputs, usually 3.5 mm plug jacks. Most wireless camera receivers use the traditional RCA type larger connectors. They make adapter cables to get from what you have to what you want. Finally the PC should have software to choose where the video and audio signals come from. So it depends on the PC configuration and the PC software. For the audio you would use the audio Line In. Do not use the audio Mic In.
