Handheld and Lapel Microphones
A handheld microphone, which an individual holds to amplify their voice. Most useful for instructors who do not need their hands free when presenting. The handheld microphone can also passed around the room for students to respond to questions when there is no student Catchbox.
A lapel microphone (also known as a LAV, lavalier or instructor microphone) includes an audio pack and a clip to be fixed to clothing as an individual presents. The setup allows for an individual to have their hands free when presenting while still having their voice amplified.

Document Camera
A document camera projects the surface beneath it through the data projector. This is particularly useful for individuals who seek to use short, written examples or illustrate points in a presentation by manipulating small objects or photographs. It allows the audience to see a small surface on the larger classroom screen.
(1) A full podium with a computer to provide access to technology in the classroom.
(2) A document camera which can magnify objects and display them using the data projector.

Lecture Capture
Lecture Capture technology allows instructors to capture the images or presentation displayed on the projector in the classroom, along with the audio captured by the instructor microphone. By inserting a USB stick into the console, instructors can save the lecture capture recording for their use in the course (ie. to upload to onQ for students to access).
Find a quick tutorial on using the lecture capture system in the Classroom Technology section.
