Jitter supports almost any webcam your OS supports.

If you’re on XP, and the camera has WDM driver(all non-ancient ones
usually do), it should work with jit.dx.grab;

If you are using OSX, usb webcams are a but trickier, but a lot of
them work with macam component. check macam list of supported cameras
at:

http://webcam-osx.sourceforge.net/cameras/index.php

Best way to check would be to download macam, go to store, plug
camera and check if it works right on spot.

Firewire cameras should work on both systems with not much fuss.

My recommendation would be unibrain Fire-i, checkout list archives
for tales of that legendary device(you can connect many of them at
once, they can use external power supply, have nice ‘uncompressed’
stream… heck, they even ship to Serbia!).

Best,

Basic problem with most of the usb webcams is their video compression. This is due the limited bandwith of usb 1.1. Most cams still just support usb 1.1 and not 2.0. Those cams that do support USB 2.0 are working fine and a pretty good alternative to firewire cams. I have a few "quickcams for notebook pro" working wiht jitter. Tiny cams with a video resolution of 640 x 480 (you can take 1.3 megapx stills) that don’t use the nasty compression by supporting USB 2.0.

There are bigger cams from logitech too that come with USB 2.0 and a res of 640 x 480.

Hope that helps.
