For our clients, we use a sled with three cameras attached: face,
screen, and keypad. These are tiny security cameras with different
lenses on them. We run the three cameras, plus a wideshot camera, into
a portable quad mixer (targeted at the security folks, again, but
works fine for us).  We then record the four images.

Synchronization is very difficult. My photo specialist explained it to
me once, and I don't have it fully integrated.  The explanation
included the fact that different cameras run at slightly different
speeds, causing mismatches to accumulate.

I've got a presentation up on slideshare on usability testing, it
includes some pictures of different setups.
