> I am really curious about the type of video hardware people are using.
Long time ago, in a far far away company ... I used some boards based on Conexant BT878 chipset. The driver for this is bktr(4). As an application, I compiled something called camserv if I remember corectly, since it was not available as a port for OpenBSD. It is an app who can extract jpeg images for you and allows http web connection to it. I was extracting those images using some php framework and did some animation in another web page.
