It's all been done:
CCTV, video over ip, video recording, motion detection, etc.

At 30 frame/sec and 320X240 grayscale resolution, you will need:
30*320*240*16*8 = 294912000 bits/sec
w/o the overhead of packet headers. Your best bet is a gigabit ethernet.

If your chipset is bt8xx, linux is well supported even w/ v4l2.
You dont need the windows software. For viewing, you can find many v4l2
compliant video viewing/recording (eg xawtv).
