For several years, the TRC has circulated portable Elmo document cameras to EDHD and teacher education faculty and students. They have been used for hundreds of classes and presentations on campus and all over the world because they are convenient to use, very compact, reliable and produce a good image. We just purchased 8 new models that support 4K video and provide both HDMI and USB connections. They are ready to circulate today.
