media server linux software

Need pointers to setting up A/V monitoring over WiFi of the basement playroom.?
I am looking for a pointer to some instructions or personal experience that would assist me in setting up a system that I could use to monitor the kids in the play room. I have an extra laptop, wireless network, Linux experience. I can purchase probably a camera and microphone for the laptop. I imagine there are some instructions out there that recommend video and audio devices that are compatible with Linux and some sort of server software that would allow my wife and I to logon to that box from another computer in the house and pick up that a/v feed when we wanted to see and hear what was going on (floors and walls seem to well soundproofed in this new house).
Keywords that I am using to search (Linux, monitor, Audio, Video, security) are of course coming up with the wrong stuff.
There is a place I could put this and get two video feeds so that is desirable too.
I would expect the Linux server to be able to stream something that Windows Media Player could use.
Here are some slightly outdated results from when I did a search on this a year or so ago: ... but ....

The two dlinks below are outdated, but the one gives an old product number which i searched on the site:
http://www.dlink.com/products/category.asp?cid=60&sec=0
http://www.dlink.com/products/?pid=297 (good)
http://www.dlink.com/products/?model=DCS-5300W (better) (my coworkers rating)
I also did a keyword search ... those links are below.
good luck
