AirMedia – Technology that allows presenters to connect their devices (laptop, smartphone, or tablet) to the AV system in a classroom or event space wirelessly. This requires a very simple setup process that we are happy to assist you with.
Crestron – Brand name of the hardware used to control the AV system in a given classroom or event space. This is often used to refer to the control panel itself.
Data/Video Projector – A projector transmits an image from a source and projects it on to a screen. The term “data” is used for a projector that can transmit images from data sources, such as computers, as well as video sources, such as VCRs.
Digital Camera – Also called a digicam for short, a digital camera refers to a package of equipment that includes the following items: camera, tripod, extension cord, and wireless microphone. This package can be delivered by Event and Classroom Management (ECM) staff to Arts, Sciences, and Engineering (AS&E) classes only.
Document Camera – Also called a digital visual presenter, this type of camera allows instructors to project images of physical documents onto the screen of a classroom or event space. Unlike an overhead projector, which shines light through a sheet of transparency paper, a document camera uses an actual camera to broadcast the image digitally.
Dongle/Adapter – When the laptop or tablet that you would like to present from does not have the type of connection that the classroom or event space allows, you will need an adapter. The ECM Help Desk has a large collection of these (over 15 types) and can deliver them to faculty upon request.
HDMI - A digital connection capable of transmitting high-definition video and high-resolution audio through a single cable. Many of our newer classrooms, meeting rooms, and event spaces support HDMI connections.
Lectern – The term “lectern” typically refers to the station at the front of a classroom from which faculty and instructors present their materials. Lecterns often house the AV technology of a given classroom. This is not to be confused with the term “podium,” which refers to the raised area or stage that a lectern can often be located atop.
Overhead Transparency Projector – A box on which transparencies can be placed and projected. A bright lamp inside the box shines through the transparency to a mirror on an arm above the box ("overhead"), which redirects the light forward. In the classroom setting, overhead projectors are often used to display printed transparencies and to instruct by writing on transparencies with a marker.
RCA – RCA ports are used to connect devices via composite video (typically yellow) and stereo audio (typically red and white) cables. These ports can be used to connect analog video devices such as VCRs and DVD players to classroom data projectors.
VGA – An analog computer display standard that is transmitted through a 15-pin connector. While VGA was the standard display port for many PC laptops, it is being phased out in favor of newer connection types. Devices that do not have VGA ports can still connect using a VGA dongle.
