Classroom Technology


With the increased focus on making instruction sessions available to both in-person and online audiences, a number of classrooms on all three campuses have been upgraded with ceiling-mounted web conferencing cameras and condenser microphones. These classrooms make it easy to teach a traditional in-person lecture that can be viewed simultaneously by students online or recorded for review at a later time. This page will go over the basics of what you need to know to get started teaching in these rooms.

(For a short video walk-through of the basic steps to take to teach a class streamed to Zoom with a PowerPoint presentation in a web conferencing classroom, please check out the Quick Start Video below).


You will likely get started at the podium at the front of the room. The instructor's PC should be on and logged into to a classroom account when you arrive. (If the PC's monitors appear off, just move the mouse to wake them back up.) 

Each classroom PC has the same two monitor setup for instructors to work with (see photo below):

Typical monitor setup for classroom PCs

When working at the podium computer, keep in mind the following:

  • These monitors are set up to function as an extended desktop (meaning items can be clicked and dragged from one screen to the next.)
  • The larger, widescreen monitor (usually - but not always - on the left) duplicates what is seen by the students on the classroom displays and/or projection screens. For that reason, this is the monitor to use for in-class presentations.
  • The second smaller screen should only be visible to the instructor and can be used to keep track of Zoom sessions or display notes or anything else that doesn't need to be seen by the class.
  • The larger monitors all have touchscreen capabilities, which can be useful when using the whiteboard functions in either Zoom or Collaborate. Styluses can be used with these monitors, but please note that not all styluses are compatible.

Turning on displays and sound system

To turn on the display screens and sound system in any of the classrooms, you will need to use the room's AV control panel. This is generally (but not always) a white panel on the wall near the podium (see photo below).

Before starting a class, you will want to take the following steps:

  1. Make sure that that the "On" button at the the top left is selected. This will turn on the room's display (which will be either a projector screen or a large monitor facing the class) and sound system.
  2. Select a presentation source. For most PowerPoint, PDF, or internet presentations this would be the classroom PC. You can select this by clicking the PC button from the choices at the right (if it's not already selected).


Each of the web conferencing classrooms is equipped with a ceiling-mounted condenser mic, usually located near the front of the classroom (see photo, below).

These mics connect to directly to the instructor PC, so they will work with Zoom and Collaborate, but will not tie in to the room's sound system. In smaller classrooms (24 or fewer seats), they have pretty good coverage of audio from both the instructor and the class. In larger rooms, the students might not be heard by the online audience but the instructor should be clearly audible.

Many of these rooms have additional mics available at the instructor's computer. These only connect to the sound system in the room, but are useful if students sitting in class are having trouble hearing you. Depending on the room, you may have a choice of the following:

  • Lectern mic. These mics are usually on by default. If you are planning on staying within a short distance of the instructor's workstation, this should allow you to be heard by both your local students.
  • Wireless mics: Either a lavalier or handheld. Likely the better choice if you plan to move around as you teach. These should connect to the sound system automatically when turned on.

Tips for using microphones
  • For lav mics, make sure mic is placed around the middle of your chest, about four or five inches from your chin, with the mic pointing directly at your face. (The mics swivel on the clips to enable best placement).
  • If using a wireless mic, be careful not to speak directly in front of the lectern mic, as this may cause interference or feedback.
  • While IS makes efforts to ensure all the wireless mics have fresh batteries, bringing a couple AA batteries as a backup is recommended.


The updated classrooms have overhead cameras that transmit to Zoom or Collaborate (see photo below), usually located on the ceiling near the center of the room.

Cameras are generally mounted on the ceiling near the middle of each room

Each camera is controlled by a black and grey remote control with the name "Aver" at the bottom (see photo below). For setting up your video calls, the two functions you will want to be most familiar with are the following:

  1. Pan and tilt: The camera angle can be adjusted using the remote's four directional arrows.
  2. Zoom: Beneath the pan and tilt buttons are two controls for adjusting the level of zoom on the camera.

Sharing presentations to online and in-person audiences

If you are planning on sharing an on-screen presentation (like a PowerPoint or pdf document) to both an in-person audience and an audience watching online, you will want to be careful that both audiences will see the same thing. To start, you want to make sure you have opened your presentation to the larger, widescreen monitor at the instructor's workstation, as this will ensure it is seen by the local students. From there, the directions vary by which web conferencing tool you are using. Specific directions for Zoom and Collaborate follow below.


In Zoom, once your presentation is open, click the green "Share Screen" button at the bottom of your Zoom window. This will open up a window, similar to the one in the image below, which will give a number of options for sharing to Zoom. From here, take the following steps:

  1. Select the whole screen with your presentation on it, (rather than just sharing the application with your presentation, like PowerPoint). In most of the classrooms this will be "Screen 1", but to be sure, look for the large white numbers that appear at the top left of each of your monitors, as these will identify "Screen 1" and "Screen 2" within Zoom.
  2. If you are going to be sharing video content with your class, select both the "Share sound" and "Optimize for video clip" options at the bottom of the selection screen.
  3. Once you are finished with these selections, hit the blue "Share" button. There should be a thin green border around of your widescreen monitor if you have shared the correct content.

Collaborate's screensharing works in a similar fashion. Once your presentation is open, access the Collaborate panel by clicking the purple tab at the bottom right of your screen (see photo below).

Collaborate meeting with panel control highlighted

This will bring up the Collaborate Panel on the right hand side of the screen. From here, take the following steps:

  1. From the bottom of the Collaborate panel select the third tab, labelled "Share Content".
  2. From the options for sharing content that appear, select "Share Application/Screen."

Collaborate Share Content Panel with option highlighted

This will bring up the dialog you see below. From here:

  1. Make sure the "Entire Screen" option is selected at the top.
  2. Select the image from your widescreen monitor from the two choices of screens (this is usually, but not always, "Screen 1").
  3. If you plan to share any video or audio content, select the "Share system audio" checkbox at the bottom.
  4. When done with these selections, hit the blue "Share" button, and you should see the correct content displaying in your Collaborate session.

Using the Overhead Document Camera

Overhead document camera

Many of the classrooms have built-in overhead document cameras, located by the instructor’s computer, that can be used to display documents, diagrams or formulas to students in class. To select these cameras as the source for the in-class projector/displays, return to the AV panel and select the button labelled "Doc Cam." The feed from the document camera should now appear on the displays the in-person students can see. Please note: these cameras will not connect directly to Zoom or Collaborate, so you will only want to use them for in-person sessions. Please see the instructions for USB document cameras if you need to share with an online audience.

Adjusting the image from the document camera can be done with the Wolfvision remote (see image below). Use the zoom control (1) to zoom the image in and out, and use the autofocus button (2) to turn the auto-focus on and off to quickly get the image in focus.

Using a USB document camera with Zoom and Collaborate

For faculty who would like to use a webcam for both in-person and online students IS will, upon request, provide portable USB document cameras that can be used both with the in-class displays and Zoom or Collaborate.

KODAK NUSCAN document cameras are available from the Help Desk

These will plug directly into the computer at the podium and can then be selected as a camera source within your online meeting software. Instructions for using these document cameras with both Zoom and Collaborate follow below.


To share the cameras with your students on Zoom, you will want to select the green "Share" button at the bottom of your Zoom meeting window. This will bring up a window like the one below. From here, take the following steps:

  1. Click the "Advanced" tab at the top right.
  2. Select "Content from 2nd camera"
  3. Click the blue "Share" button at the bottom right.

Zoom share selection screen photo

The video feed should display in the Zoom window on your desktop. For your in-person students to see the document camera, make sure that the window sharing the camera is on the widescreen monitor that duplicates to the larger classroom displays.


To share the cameras with your students on Collaborate, you will first want to open up the Collaborate panel by clicking the purple tab at the bottom right of your browser.

Once the Collaborate panel pops out, you will want to do the following:

  1. Select the third, "Share Content", tab at the bottom of the panel (circled below).
  2. Then, from the choices available, select "Share Camera."

The video feed should display in the Collaborate window on your desktop. For your in-person students to see the document camera, make sure that the window sharing the camera is on the widescreen monitor that duplicates to the larger classroom displays.

Using the Zoom Whiteboard

A number of faculty find it challenging to use the physical whiteboard in the classroom or lecture hall while also trying to accommodate students watching online. One workaround is to use the Whiteboard feature in Zoom. When shared to the large classroom displays, this feature allows faculty to sketch formulas, notes and drawings that both the online students and in-person students can see. Additionally, since it works with the touchscreen functionality of the widescreen classroom monitors, faculty can draw fairly naturally using the Whiteboard, especially when using a stylus.

This feature can be accessed by clicking the green "Share" button at the bottom of your Zoom meeting window. From the selection screen that pops up (see image below), do the following:

  1. Select Whiteboard from the available options
  2. Click the blue "Share" button.

Zoom sharing selection screen

This will bring you to a screen like the one you see below.

Zoom whiteboard image

As with sharing any presentation, make sure to display the whiteboard on the larger monitor that feeds to the in-class displays, so that your in-person students can see it. The Whiteboard defaults to the "draw" setting and either the mouse or touchscreen can be used to draw on the whiteboard.

Wrapping up

Remember to do the following upon finishing a class:

  1. Turn off the in-class projector/displays. Hit the "Off" button under the "Display" heading at the top left of the AV Control Panel.
  2. Turn off any wireless mics you may have used. Some of the lav mics don't have an on-off switch. These can be turned off by pressing and holding the "Mute" button until the display on the mic goes dark.
  3. Make sure you have logged out of Zoom. If from the Zoom home screen you can still see an icon with your initials or profile photo in the top right corner (see image below), (A) click on that icon and (B) select "Sign out" from the drop-down menu that appears.

    Zoom home screen image

  4. Close all open browsers and applications. This is especially important if you logged into any online accounts like email or Blackboard, as the next people using the classrooms may be able to access your accounts if any browser windows are left open.

  5. Leave the instructor's workstation on and logged in to the classroom account. Additionally, if you made any changes to the desktop's configuration, please set them back to how they were when you arrived.
