Classroom AV Equipment

UNT classrooms are outfitted with a variety of equipment depending on the room size and needs. Below you will find a sampling of equipment that may or may not be available in the classroom you use. Although a room may be more fully equipped than others, we try to standardize the equipment to minimize learning curve and provide a consistent experience around the university.

AV Equipment

Data Projector

Projector mounted to ceiling
Data projectors are installed on the ceiling in all DSI Tech-supported rooms. The data projector is controlled from the installed instructor computer. 


  • Use the AV Controls program to turn the projector on or off, select a display source, blank or un-blank the image, or adjust the volume.

Standard Instructor Computer
  • Each classroom has an computer for instruction purposes.
  • Please see below for software available on the computers. You may install your own software, but the computer will be re-imaged weekly, returning the computer to a known state. For this reason, we recommend you keep your work in a cloud storage service (such as OneDrive) or on your office machine.
  • If you require software for instruction that is not available on the machine on a regular basis, please try using Remote Desktop to connect to your office machine (or other machine that contains the software you need) or utilize the app virtualization services provided by the VMWare Horizon Client. Please contact us if you have a special use case.
  • Remember that a computer has its own volume control, so it may be necessary to un-mute or adjust the volume level on the computer as well as the data projector to get the desired sound level.

Multipurpose Camera

Multipurpose camera
Each classroom is equipped with a small 2-in-1 multipurpose camera with a built-in microphone that can function as a document camera or webcam for software such as Zoom, Teams, Canvas Studio, etc.

Some classrooms may have an HDMI cable routed through the instructor podium. 

Wireless Microphones

Wireless transmitter with mic docked in a charger

Wireless microphone systems are installed in the larger DSI Tech-supported rooms. In the past, instructors were required to check out a transmitter, but now each room will be equipped with a transmitter bodypack unit that is already synced to the same frequency as the receiver. Rooms equipped with a wireless microphone have a charging cradle containing the transmitter and microphone, as well as a spare rechargable battery. If a room is missing a transmitter, please contact us to get it replaced.

NOTE: Rooms equipped with ceiling microphones mix both ceiling and wirelss mics together, please see "Ceiling Microphones" below for the correct audio source.

  • The system can be used for voice amplification, as well as an input into lecture capture or web conferencing software.
  • To use the wireless microphone as an audio input, please select "Microphone (Sound Blaster Audigy FX)" in the audio source selection drop-down menu.

Document Cameras
Wolfvision document camera VZ8 Light4
Most larger rooms are equipped with a desktop-mounted document camera, or visualizer, which allows the entire class to see a document or handwritten work on the projection screen.

  • The visualizer is accessed by running software on the classroom PC, which can be launched by clicking on the "Visualizer" button on the on-screen projector remote.
PTZ Instructor Cameras
PTZ Optics camera

Most general-purpose rooms are equipped with a pan/tilt/zoom (PTZ) instructor camera. These cameras allow the front of the room to be captured on video and used in conferencing software such as Zoom, Teams, etc. or used to record a lecture in Canvas Studio or similar software.



  • To control the camera, please use the "Camera" tab on the on-screen remote controls (shown below). Three presets ("Pre 1", "Pre 2", "Pre 3") are available to preset the camera shot for front-of-room wide shot, instructor close up, and the nearest whiteboard.

Full-coverage ceiling microphones are available in a select number of rooms, which allow the entire class to be heard or recorded.

NOTE: Rooms equipped with ceiling microphones will sound best on a call or video conference when paired with the wireless instructor microphone. 

  • To use the ceiling microphones in Zoom, please select "Echo Cancelling Speakerphone (TesiraForte)" in the audio source selection drop-down menu.
