Camera software?

I have two webcams from Logitech but none of them has software for Mac OS. I found this MACAM but it doesn't seem to capture sound and I need a program which will capture video and sound at once cuz synchronizing is a bit annoying. Anyone has a software that might help me, I would be very glad.


PS. both cams are on USB ports so Keycam didn't work.

What are the specific models for the Logitech cameras? Are you thoroughly searching their website? I haven't had any problems finding drivers for Mac OS. If anything, I would expect problems with various Linux distributions, if at all.
