Device is mounted from the ceiling that projects an image onto a screen or whiteboard in the classroom.  Integrates with the video system to display different sources like computer, laptop, document camera, and blu-ray player.


Most GP Classrooms have a Windows computer, a limited number of spaces have both Windows and Mac machines available for instructors. All classrooms have HDMI cables that instructors can use to connect their own laptops. ITS does not provide adapters in the GP classrooms. 

Control Interface

There are two types of controls in GP.  Most smaller classrooms have a simple keypad to turn on the projector, change source, and adjust volume.  Larger or more complex rooms will have touch screen controls to adjust additional features such as microphones, cameras, and lighting.

Document Camera 

Used to display three-dimensional objects, opaque items. Also called a "digital presenter." A camera with articulating arm that points down at the table to display printed content or can be used to project hand-written notes or annotations. 

Apple TV

Device used to display content wirelessly from Apple devices.

Microsoft Wireless Display Adapter

Device used to display content wirelessly from Android or Windows devices.

Lapel Microphone

A wireless microphone that clips to a shirt collar, or lapel, to be worn by the instructor. The lapel microphone cord is connected to a transmitter that clips onto the instructor's belt.

Handheld Microphone

A wireless microphone that is held in the hand. Often used by singers and musicians on stage. Used in classrooms as a backup for instructors or to pass around the audience. 

Sound Re-enforcement

Wall-mounted or ceiling-installed speakers that amplify the audio from source content (i.e., lecture, video, and/or music) and microphones. 

  • Program Audio - audio coming from source content

Student Response System (SRS)

ITS supports iClicker base stations and clickers in GP classrooms. Instructors can also use the iClicker Cloud service in classrooms.

Lecture Capture

A recording of the class that includes the presentation/source content, along with room and instructor microphone audio. The recording may take place on the classroom computer using software or through dedicated hardware in the room.

Hearing Assistance

An audio system that allows sound to be broadcast around the classroom to available ear-worn receivers or to a person’s hearing aid. These are available in many large GP classrooms. Signs are posted in the room to notify occupants of this capability. 

Web Conferencing

Web Conferencing-Instructor Only (W): These classrooms will have equipment necessary to record/transmit video and audio (via Zoom, Skype, etc.) of the instructor, but no capability for recording/transmitting video or audio of the students.

  • Instructor uses lapel microphone (On/off and volume-controlled in Zoom)
  • Large rooms may have additional manual AV controls separate from Zoom controls
  • Remote students can hear instructor and respond to the Zoom-room
  • On-site students can ask questions to the instructor, who must repeat the question for remote students to hear
  • Room has remote-control camera, usually pointed at instructor's area
  • Screen-sharing shows presentation materials (Document camera can be connected to the classroom PC, so it could be used with Zoom. This would be activated by the second camera option in Zoom.)

Web Conferencing with Student Participation (WSP)

These classrooms will have equipment necessary to record/transmit video and audio (e.g., Zoom) of the instructor, as well as audio from students. 

  • Uses the same features as Web Conferencing-Instructor Only (W) but also includes overhead ceiling microphones, allowing remote students to hear everyone in the classroom
  • Instructor can wear lapel microphone or rely on overhead microphones for audio
  • Ceiling microphones are on all the time (have the option to add control buttons on room touch screen user interface)
  • This option is generally limited to small- and medium-sized classrooms

Classroom Camera

A pan/tilt/zoom camera pointed at the front of the room.  The camera can be used for lecture capture or Zoom from the classroom computer.  Camera can be controlled through the remote or may be integrated into the classroom control interface.

Blu-ray Player

A disc player mounted in the equipment rack for video playback of Blu-ray Discs. Also plays DVDs.

HDMI Cable

A digital video cable for connecting laptop audio and video to be displayed on the projection system. A  adapter is often needed to connect the laptop to the cable. ITS does not provide adapters.

VGA Cable

An analog cable for connecting laptop video to be displayed on the projector system. A separate audio cable is available. A laptop adapter is often needed to connect the laptop to the cable. ITS does not provide adapters.


The desktop display unit for the computer or other selected source. Displays the same image as the projector.
