Baby Monitor,
Would love to help , but you are suggesting connecting a 2.4 mhz radio to the internet with no ethernet port or wireless 802.11x available locally.
If this is for just around the house a wireless 802.11x camera with the software above.Would work best. As long as you have a PPC with 802.11x
I would suggest a Axis 210 or 207
www.axis.com or any IP camera for the situation of monitor the baby/sitter kind of thing., or from work, on a trip etc
With the software above...
Hope it helps !!
