Hey, I'm a document camera newbie. Can anybody give me a clue what I should expect? In my mind, a document camera is just a webcam that points downward to focus on a paper or whatever, 1ft below it on a desk, right? So you could use the document camera in something like skype or ooVoo if you wanted to, no? Perhaps you could even tilt it upward and use it like a regular webcam?
document cameras have a few differences in their requirements (that may or may not result in differences in the hardware)
the focus requirements are much less (you don't need much depth of focus, and you seldom need to re-focus)
frequently document cameras include lights to illuminate the document.documents really do need higher resolution than most webcams (640x480 just won't produce a readable document)
Here's the requirement I need to satisfy: People need to be able to share physical documents and/or whiteboard with each other in different states - Am I not able to use something like skype or ooVoo?
what I would suggest is to take a normal digital camera and take pictures of things with various resolutions and then look at the results.
video conferencing software is probably _not_ the appropriate thing to use to transmit the images, that's aimed at low-res moving images and you need high(er)-res static images. you may be best off just e-mailing the pictures around or putting them on a web page.

Maybe the only way to learn this is to go to the store and put my hands on some.
