wireless network camera

I’ve done some searching but can’t seem to nail down this information.

What is the story on using network cameras (like this

In jitter. It seems that sometimes they work with windows but not quicktime?

I need a wireless camera with fisheye capability to run on a intel mac mini.

Any suggestions,
Thanks again
