 What is the difference between Alternative Host and Co-Host?

Alternative host option allows you to schedule meetings and designate another Licensed user on the same account to start the meeting if you are unable to.
  • This user will receive an email notifying them that they've been added as an alternative host, with a link to start the meeting.
  • The alternative host will need to use the link in the email or have the calendar invite sent to them by the original host and use the join link there.

Scheduling privilege is designed for a someone like an Executive Admin or Secretarial Duties:

  • Can assign or delegate a user or multiple users in your account to schedule meetings on your behalf.
  • You can also schedule meetings on behalf of a user (or multiple users) that has assigned you scheduling privilege. 
  • Users with Scheduling Privilege on your account will be able to manage and act as an alternative host for all meetings.

Co-Hosts feature allows you to share hosting privileges with another user in a meeting.

  • This can be useful to allow another user to manage the administrative side of the meeting, such as muting participants or starting/stopping the recording.
  • Co-hosts are assigned during a meeting and cannot start a meeting.
  • If a host needs someone else to be able to start the meeting, they can assign an Alternative Host.
  • There is no limitation on the number of co-hosts you can have in a meeting.

    • 600kbps (up/down) for high quality video
    • 1.2 Mbps (up/down) for 720p HD video

 Mac Webcam Security

There is a slight security breach possibility for mac users who use Zoom. Here is the article:

Zoom has addressed this issue:

Since then, participants will not join the meeting with their video on automatically. There is now a video preview which will pop-up first. Participants will have to manually select to join with video or without video.
Other settings to ensure the security of our NUS Community:

1) Template for meetings created in LumiNUS, does not enable start meeting with video for both host and participants. Videos are to be started by each individual manually in their Zoom meeting.

2) New sign-ups to NUS Zoom Accounts will have the below settings turned off as default:

  • Host video: Start meetings with host video on
  • Participants video: Start meetings with participant video on. Participants can change this during the meeting.

Once again, if a host in NUS intentionally schedules a meeting that requires participants video to be on, participants will see a video preview pop-up asking them to join with video or without.

 Change your display name

There are two methods to change your display name in a Zoom Meeting.
Profile Page
  1. Go to and sign in.
  2. Click on Profile.
  3. Type in your First Name and Last Name.
  4. Click Save Changes.

In a Zoom Meeting
  1. Click on Participants button.
  2. In the Participant Panel on the right, look for your name (it's at the top).
  3. Click on "More" button beside your name, and select Rename.
  4. Type in your preferred display name.

    Manual Breakout Room Tip

    For easier manual Breakout Room grouping, you may want to ask students to rename themselves with their group names at the front.
    Example: Gp1_Adam, T1-Adam or 1-Adam.

 There is Echo...

Sometimes you will hear audio echo or audio feedback during your meeting. For bigger groups, it is advisable to select "Mute Participants on Entry". For even larger groups, you may want to prevent students from unmuting themselves.

To solve the Echo issues:

1) Isolate the participant
As a host, if it is a small group, you can do a Mute All and unmute individually to find the source. You might not have a time to do this in a big group. Do a Mute All and let them know to unmute only when given permission to talk.

2) Cause of Echo

  • Participants not joining using headsets and joining using external speakers. So what happens is the built-in mic picks up audio from the external speakers causing echo from other.
    Unfortunately, in most cases the one causing echo will not hear the echo.
  • Two or more participants with active audio joining from the same room (physically). If that is the case, only one device should Join Audio. All other devices should Leave Audio.


 Speakerphone Devices

It is not possible to have 10 member is the board room to share the mic from a single laptop.

While there are products meant for bigger rooms like the Logitech available for purchase, there are existing equipment that your office may already have.
Most offices in NUS will have the the Polycom Trio used for boardroom telephone calls. That Polycom Trio can also be connected to a laptop; either Bluetooth or USB.


Use a Micro USB cable to connect the 
Polycom Trio with the laptop.
Select the Polycom's Speaker and Microphone device in Zoom.
Run the Test Speaker and Microphone to configure it.

 Breakout Rooms

Breakout rooms allow you to split your students into their discussion groups. The Host can split them automatically or manually.
