We've been in the document camera business 9 years and have introduced many innovations: the first document camera with fully rotating camera head; the first with LCD viewing monitor; the first with electronic annotation writing tablet. The Justice Visions JV-850K incorporates a digital camera with a refresh rate approaching 30 frames/second providing extremely smooth images. We also offer a 4-million pixel "Intelligent Vision" all-in-one document camera/projector with glass platen for extremely clear images, the AVIO iP-40 (If you are at a school or college, please check our Education page for special education pricing.)
