Technology Enhanced Classroom Tips & Tricks
Below are a list of situations or problems you may run into while teaching your Tech Enhanced class as well as specific information for particular rooms across campus.
General Information
If there is a room upkeep issue, please call 504.865.5441
If the room’s telephone is not working
Open a ticket and assign it to ‘Telecommunications – Uptown’ with all relevant information (including room number and building)
If clock time in the room is incorrect
Open a ticket and assign it to ‘OnSite – AV’
Find out class start times and keep a route of classes
Go to rooms before the start to make sure professors are set up and go back to rooms after start time to make sure classes continue to work
Be visible but don’t interrupt
Cameras
To identify the camera model in each space, open Zoom and select the carat on the ‘Start Video’ button. If the camera is not identified by Zoom, locate the camera in the room and check the manufacturer logo on the device.
Vaddio Roboshot
This is the most common camera found in hybrid classroom spaces.
They can be mounted to a ceiling or wall (this should be noted for troubleshooting)
Issue | Action or Solution | Explanation |
Camera will not tilt or pan |
| In some spaces the cameras are mounted in tight corners where wiring is running between a wall and the camera’s mounting cradle. Panning and tilting the camera can pull the cables or force them into a spot where the camera motor will begin to experience resistance from the cable placement. Once a camera stops responding to tilt and zoom commands, do not continue to send pan and tilt commands via the remote. Verify bunched or stuck cables are not binding the camera’s motor or preventing its movement. Where other remote buttons are not functioning in addition to pan and tilt, see the section below for unresponsive remotes. |
No image in Zoom when camera is powered on |
| Powering the camera on and then off typically resolves this issue but if it does not then the issue is likely related to the USB hub. The USB hub can be power cycled but this should only be done by an AV Support Professional with access to the rear internal lectern. There are a number of components inside the lecterns and power cycling the USB hub may lead to other issues that would require AV Support to properly identify and reconfigure. |
Unresponsive remote |
| Vaddio has been tasked with meeting a large consumer demand in a very short period of time. The reliability and longevity of products manufactured by Vaddio in the last few months is yet to be determined. There has not been a sufficient break-in period on the equipment purchased by Tulane for these spaces. Manufacturer’s defects are likely and the remote simply may not be functional. There also may be interference to the infrared signal due to other devices or fixtures in the space. |
Yellow or green tinted image |
| Power cycling the device has worked in solving image discoloration issues in most spaces. The devices are POE or powered over ethernet, therefore it is only necessary to pull the ethernet cable to the back of the device to power cycle it. They are not powered by any other cable. Vaddio has been tasked with meeting a large consumer demand in a very short period of time. The reliability and longevity of products manufactured by Vaddio in the last few months has yet to be determined. There has not been a sufficient break-in period on the equipment purchased by Tulane to identify all defective equipment. Manufacturer’s defects are likely and the camera may be defective if the issue persists or occurs frequently. |
Vaddio Roboshot FX
This model is found in a smaller number of spaces (mostly auditoriums or integrated Classroom in a Box builds that work with previously installed equipment
Issue | Action or Solution | Explanation |
Camera will not pan ortilt |
| The Roboshot FX model does not offer pan and tilt functionality via remote. They can zoom however. These models were placed in larger classroom spaces where the camera is in close proximity to the lectern and can be reached easily if pan or tilt are required for instruction. It is possible that these models were inadvertently placed in a location where a standard Vaddio Roboshot was meant to be used so identifying the model in Zoom is key to quick troubleshooting |
No image in Zoom when camera is powered on or Unresponsive remote or Yellow or green tinted image (aka Predator vision) | See above camera model section for troubleshooting | See above camera model section |
Sony SRG
This model is found in all temp structures (Newcomb Quad, Berger Family Lawn buildings, and Monroe Quad structures)
Issue | Action or Solution | Explanation |
No image in Zoom (black screen) when camera appears powered on |
| The camera may be receiving a stale signal or no signal from the POE injector or the camera is hooked into the PC via a USB hub that needs to be rebooted. Both devices are locked inside of the rear compartment of the lectern and should only be handled by an AV support professional. |
Unresponsive remote |
| The remote could be defective or the infrared receiver on the device may de damaged, defective, or receiving interference from other devices or fixtures in the room. |
Confidence Monitors
Not all spaces contain confidence monitors. These are typically reserved for high builds, low builds, and select classroom in a box builds. The 65 inch Panasonic screens may either appear mounted at the rear of a classroom, on a side wall, or be present on a floor stand.
Issue | Action or Solution | Explanation |
Confidence monitor will not power on from Lectern Controller |
| Depending on the vendor that built the room, different coding methods were used to program the controller buttons. As with all code, there is debate as to the most efficient method to program and some devices may be slower (have more code to process) as a result. A confidence monitor that is plugged in and ready to receive remote or controller commands will have a green light on the bottom left side of the bezel if it is ‘On’ and red light on the bottom left side of the bezel if it is plugged in but powered ‘Off.’ |
Confidence monitor is displaying a mirrored display instead of an extended display |
| Not all spaces are used in the same manner and some instructors may prefer a mirrored display to prevent confusion. If an instructor wishes to have all remote zoom participants on one screen they should extend the display and move the corresponding zoom window to the confidence monitor. |
Confidence monitor is on but not displaying anything |
| This typically appears to be the case when powering on the system. The confidence monitor is not the primary display so it will appear to be a black screen on a powered on device until a user has logged in. |
Touch monitor is not the primary display |
| The display that is not primary in any configuration will display a black screen until login is complete. |
Controllers
These are the black boxes attached to lecterns with labeled light up buttons with fixed commands assigned to each labeled button. The button assignments are programmed with Python and depending on the efficiency of the code written by the programmer the controller can demonstrate delayed responses.
Issue | Action or Solution | Explanation |
Display On does not power on all display devices |
| Depending on the vendor that built the room, different coding methods were used to program the controller buttons. As with all code, there is debate as to the most efficient method to program and some devices may be slower (have more code to process) as a result. Devices should still be capable of powering on using on-board buttons or by using their respective remote controls (stored either in the lectern drawer or on the surface of the lectern) |
Slow or unresponsive buttons |
| Depending on the command being sent by the controller it may be tied to a slow responding device. Projectors for example have cool down periods and will not be able to be powered on again until that cycle ends if the Display Off button is pressed. The hardware must carry out the initial command before the subsequent command can take place. |
Changing inputs does not show intended display |
| Inputs are occasionally very slow to respond after being switched. This may result in users seeing a black screen and not getting visual feedback when the input has been selected. Powering on the device attached to the new input typically will force the display to show the image from the selected input device. |
Controllers (Touch Screen Operated)
Touchscreen controllers are present in High build classrooms and other select spaces. They may have commands that are controlled by previous classroom builds or other devices if they were integrated with previously existing tech in the classroom.
Issue | Action or Solution | Explanation |
Student camera does not show up in Zoom call when activated from touch screen controller |
| Vaddio bridges are scheduled to be installed at a later date when the install impact is lowest to the semester. As a result, some high build classrooms are built as a high build but currently operating as a low build. The second camera cannot be selected until the bridge is installed. |
Displays
Most spaces are equipped with a 24 inch Dell touch monitor. This is not true of all spaces as some Classroom in a Box builds may be integrated with older equipment.
Issue | Action or Solution | Explanation |
Touch monitor does not respond to touch |
| When touch screen monitors no longer respond to touch the whiteboard feature in Zoom will be significantly more difficult to use. Touch screen monitors that are no longer responding to touch are likely hooked into an overloaded USB hub. AV Support should reboot the USB hub when power cycling the monitor does not work. If rebooting the hub does not work, the monitor may be defective. |
Confidence monitor is displaying a mirrored display instead of an extended display |
| Not all spaces are used in the same manner and some instructors may prefer a mirrored display to prevent confusion. If an instructor wishes to have all remote Zoom participants on one screen they should extend the display and move the corresponding zoom window to the confidence monitor. |
Document Cameras
The Epson document cameras are high definition camera devices that contain a microphone for recording purposes. Occasionally, the high definition camera or onboard microphone can interfere with the cameras or microphones that are intended to be used for Zoom calls
Issue | Action or Solution | Explanation |
Power On or Off does not respond |
| The document camera power buttons require a user to double tap. Document cameras will cause several different issues when they are powered on or off between user profiles. They should likely be left on at all times as there is typically not a reason to have them powered off unless the camera and microphone interfere with Zoom camera and microphone settings. If this is the case contact Tulane AV support. |
Doc cam takes over as primary camera in Zoom |
| When using Advanced Share, make sure the document camera appears as the shared camera device and not the Vaddio or Sony camera (the image from the Vaddio or Sony should not be disrupted when Advanced Share is used and should still be visible as one of the camera sources in the call with other callers’ video images) |
Microphone turns on and is used in Zoom call as the primary microphone |
| Manually adjusting the microphone and audio playback settings on the PC will put the system back into the intended state where the document camera microphone is not being used to transmit primary microphone audio. |
Image is flipped orbackwards |
| The issue is the Zoom settings and not the document camera itself. This can be easily adjusted in Zoom video settings and reverted back in the event that the preferred video setting is to mirror the selected camera image. |
Advanced share crashes Zoom |
| The document cameras will become unresponsive or crash Zoom when they are part of a USB heavy build. The USB hubs become overloaded and the document camera cannot typically work or zoom in and out of images without crashing the Zoom call. Until the Doc Cam is hooked up to the PC using a different device, it should not be used in classroom instruction. |
Zooming in or out crashes camera and Zoom call |
| The document cameras will become unresponsive or crash Zoom when they are part of a USB heavy build. The USB hubs become overloaded and the document camera cannot typically work or zoom in and out of images without crashing the Zoom call. Until the Doc Cam is hooked up to the PC using a different device, it should not be used in classroom instruction. |
Document camera image displays horizontal lines, banding, flickering, or a fuzzy picture |
| Bad cables could be present in any number of builds or it is also possible that cable seating can become dislodged as multiple users enter these spaces and interact with/move equipment. The document cameras will become unresponsive or crash Zoom when they are part of a USB heavy build. The USB hubs become overloaded and the document camera cannot typically work or zoom in and out of images without crashing the Zoom call. Until the Doc Cam is hooked up to the PC using a different device, it should not be used in classroom instruction if it is crashing. |
Microphones
There are several microphone types located throughout the new classroom builds. Handheld microphones are intended for students and will present the best audio fidelity. RevoLabs lapel microphones and Shure lavalier style microphones are present for faculty use.
Issue | Action or Solution | Explanation |
Microphone cannot be heard in Zoom call |
| Microphones should be placed back in their charging docks after each use to preserve battery life for other classes using the space throughout the day. Not all microphones are immediately active and On after being pulled from their dock (though some such as the Shure handhelds usually are). Before touching any buttons on the microphone first wait for the microphone to recognize that it has been removed from the dock as it may turn on automatically. If a button press is required to power it into an active state, patiently wait for the green light to come on after pressing the button once. Doublecheck the system audio playback device and the Zoom microphone and speaker settings to make sure they are aligned. Just because the system is set to a specific playback device does not mean Zoom automatically is set to the same device as well. |
Pressing the button on the microphone doesn’t do the intended function |
| Not all microphones are immediately active and On after being pulled from their dock (though some such as the Shure handhelds are). Before touching any buttons on the microphone first wait for the microphone to recognize that it has been removed from the dock as it may turn on automatically. If a button press is required to power it into an active state, patiently wait for the green light to come on after pressing the button once. |
RevoLabs needs two button presses to power on |
| Not all microphones are immediately active and On after being pulled from their dock (though some such as the Shure handhelds typically are). Before touching any buttons on the microphone first wait for the microphone to recognize that it has been removed from the dock as it may turn on automatically. If a button press is required to power it into an active state, patiently wait for the green light to come on after pressing the button once. Press a second time if needed after allowing the device to process the first command. |
I don’t want to clip this Shure lavalier mic to me or carry it around |
| The Shure lavalier style microphones in the temporary structures do not need a microphone attachment to work. They are still capable of picking up and transmitting sound without the cable attachment. If the microphone attachment is removed it should be neatly coiled and placed near the charging dock for the microphones or in the lectern drawer. |
There is too much feedback from a microphone |
| There are multiple microphones in the space that can create very dynamic play off of one another. Adjusting volume settings and muting unused microphones in the space can alleviate this issue. Tulane AV support can make small adjustments in most spaces if needed.
|
Lapel microphone audio is too low for my Zoom callers |
| The RevoLabs and Shure Lavalier microphones are not as powerful as the handheld microphones. Cloth face coverings will decrease the sound being pushed into the microphone |
Zoom participants say it sounds like an airplane is in the room when I unmute student microphones |
| The overhead student microphones filter out sound that is not meant to be transmitted in the call. Most of these microphone units are within one to two ceiling tiles of an HVAC vent. They will initially pick up the sound but they are smart enough to filter it out after a few seconds. However, each time they are muted they will pick up and transmit unwanted sound until the occlusion kicks in. |
Projectors
Issue | Action or Solution | Explanation |
Discoloration in projector image |
| During testing of the spaces there was projector discoloration that was observed in several spaces (small portions of the screen were purple or yellow). The issue was transient in the few cases where it was observed and typically was resolved either after power cycling or by waiting several minutes. |
Projector is showing a blue screen |
| This issue is more common in the Classroom in a Box builds. Projectors mounted to ceilings can still have this issue occur but are less likely since they are not being directly handled or are easily accessible. |
Projector displays message indicating the filter should be cleaned or it should have the bulb changed |
| This message appears on some projectors and typically goes away a few seconds after the projector powers on. Because most of the projectors are brand new, a projector displaying this message should be inspected by Tulane AV.
|
Remotes
Issue | Action or Solution | Explanation |
Pressing buttons does not produce a response on the device |
| Due to the nature of the spaces, equipment is not always consistently spaced out across each room. For this reason, remotes may not feel as responsive in one classroom as they would in another. Due to the nature of the spaces, equipment is not always consistently spaced out across each room. For this reason, remotes may not feel as responsive in one classroom as they would in another. |
Remote is missing or cannot be located |
| Instructors may inadvertently remove microphones or remotes from classrooms as they rush to leave. They may also place them in less than obvious locations in the classroom. When found, remotes should be returned to the lectern drawers or the top surface of the lectern. |
Batteries are no longer powering the remote |
| Depending on usage and storage of remotes their batteries may lose strength faster than expected. In anticipation of issues with batteries Tulane IT has ordered a large supply so remote batteries can be replaced quickly.
|
Software
Issue | Action or Solution | Explanation |
Desktop Icons or taskbar icons are missing |
| Tulane IT will use the machine’s host name to identify any issues where group policy changes did not successfully take hold on a machine. A remote push can place the needed desktop icons and taskbar launch buttons on the desktop. |
MS Office applications require activation |
| Tulane IT will use the machine’s host name to identify any issues where group policy changes did not successfully take hold on a machine. A remote push can allow office applications to launch and operate without local product activation. |
Instructor has a problem with using their laptop on Zoom |
| The laptop input switch in the lecterns and carts was only ever meant to be a way to share the content in the classroom, not across a Zoom call. The best course of action for using a laptop in a Zoom class is by making it a participant in the call with co-host capabilities.
|
Sound/Audio Issues
Issue | Action or Solution | Explanation |
Can’t hear remote students on Zoom |
| These issues typically occur when the playback device is not synced or matched to the Zoom settings. A PC might be set to the correct audio playback device but the zoom settings may not match. The opposite is also true. The majority of spaces should be set to the Extron scalar as their playback device for audio (unless supporting the temp structures where all devices are set to the TesiraForte biamp). Unless both settings are matched there are likely to be audio issues during the Zoom call. |
Instructor can’t hear themself in room over speakers when talking into microphones |
| Not all speakers are set to send the “house” sound back into the space over the speakers. This has been disabled in some spaces out of request from instructors. If sound was previously set to come through the speakers and no longer does, contact Tulane AV for support. |
Can’t hear YouTube videos over the speakers in the room or remote Zoom users cannot hear YouTube videos when they are shared |
| In some spaces the audio from a video will playback automatically. This is not always the case and the screen share with PC audio typically can take care of the problem for users on both ends of the Zoom call.

Unique Classroom Build Info
Issue | Action or Solution | Explanation |
Diboll Gallery (Commons) | Only one camera works in the space (the one located by the far windows). | To control this camera with the remote the user will need to be very close to the camera. This is not an issue with the other camera but is instead the intended design of the space. The camera that does not work with the lectern controller was intended to be part of the original build in the space and was not integrated into the Summer 2020 room upgrades for the Fall covid-19 response |
Dixon | There are several legacy/integrated build in this space with unique controller layouts and equipment. Microphone and zoom call volume runs through a mixer in a lot of the spaces. | Michael Batt provides classroom support in the building. He knows about the unique builds and how to work with them for best results. He can be reached at 504-256-7275. |
LBC Kendall Cram | Cannot locate microphones | Microphones are located behind the wall panels on the far side of the room from the entrance.
|
LBC Qatar | The controller/touchscreen cannot be located | The touchscreen is located on the wall, not the lectern. When entering the space from the hallway near Stibbs and Rathskeller, look to the wall on the left side of the room. |
Temporary Structures (Newcomb Quad buildings, Berger Family Lawn buildings, and Monroe Quad buildings) | Sound in these spaces is an ongoing issue Blackouts and brownouts are an ongoing issue in these spaces | We are aware of the sound issues and facilities is working on dampening the sound. For now, we have done all we can with air conditioning and sound adjustments. Call the Service Desk if issues are found with equipment. Do not assume that a room that worked even a minute ago will be working now as the power issues can disrupt or damage equipment very quickly. |
Woldenberg Art 208 | No student mics are present making it difficult to facilitate hybrid classroom discussion with online participants. | Some of the hybrid spaces are not designed for classroom discussion but that does not mean ingenuity can not be implemented or that classroom discussion with online participants should not take place in these locations. One solution for this space is to set the Document Camera as the primary microphone in the Zoom call (using the carat on the ‘Mute Audio’ button > Select the Epson document camera as the microphone). Then move the cart with the document camera into the center of the space. Take care to make sure cables do not get pulled into a position that may damage equipment or create tripping hazards for individuals in the classroom. Return cart to its original location at the conclusion of the discussion/class. |
