I don't really know whether any driver or software like SplitCam and VLC player will be of any help here. And I don't know whether there is any difference between connecting your webcam wirelessly and via LAN.

Can you see it as a capture device?

In VLC Player click "File" -> "Open Capture device...". Click the "Refresh list" button if needed. Can you see your webcam in the "video device name" list?
