*Zoom and services that include the name Zoom are services provided by Zoom Video Communications, Inc.

From July 15, 2022, Zoom will have a 40-minute limit even for meetings with two participants if you have a free subscription. (Previously, it was only for meetings with 3 or more people.)
Companies and organizations using Zoom for business should consider switching to a paid license at this opportunity.

Zoom video conferencing allows you to communicate while checking the other person’s facial expressions and reactions.With the spread of remote work, there are cases where Zoom has become a communication tool instead of the phone.

Some people may say that these days, there are more Zoom meetings than face-to-face meetings.

Since there are many opportunities to meet face to face through the camera, you want to give a good impression to the business partner by paying attention to the camera shine of Zoom.

Especially if you are in the position of a presenter such as a webinar lecturer.

In this article, we will introduce how to set up the Zoom camera and how to deal with the problem that the camera image is not displayed.

How to choose a camera for Zoom

You don’t have to suddenly buy an expensive camera for Zoom.

Any camera recognized by the device will do.

First of all, try using Zoom with your camera or the built-in camera of your device, and if you want to improve the image quality or adjust the angle, you can purchase a device that suits your purpose.

Camera type and connection method

Camera type and connection method

When using Zoom for business, it is basic to turn on the camera.

However, computer cameras are rarely used outside of video conferencing.

If you have never fiddled with the camera settings before, you are likely to encounter troubles such as “The camera is not set even though the Zoom meeting has started” or “The camera is not shown but I do not know how to set it.”

Here, we will introduce the types of cameras that can be used with Zoom and how to set them up.

Check your camera settings before the Zoom meeting.

PC’s built-in camera

Many laptops, smartphones and tablets have built-in cameras.

No special camera settings are required when using the built-in camera.

When you join a meeting with the Zoom app, you will be asked for permission to access your camera.

If you allow camera access, it will automatically connect to the built-in camera if no other camera is connected.

Switch between in-camera and out-camera

The built-in camera can be used immediately without initial settings, but one thing you should be careful about is switching between the in-camera and out-camera.

Laptops and smartphones may have cameras on both the outside (back) and inside (screen side) of the device, which can be switched manually.

If your video is on but you can only see the wall or you can’t see yourself, the video may be the outside camera.

If you want to participate in the Zoom meeting while looking at the screen of your device, switch to the in-camera on the screen side.

USB camera

You also have the option of using an external webcam if you want a better camera or want to place the camera wherever you like.

If you use an external camera and a tripod or stand, you can also adjust the direction and angle of the camera.

This section introduces the camera setting procedure when connecting a general USB camera to a computer for the first time.

  1. Make a USB connection between the camera and the computer. If your camera has a power switch, connect it and then turn it on.
  2. When connecting for the first time, the camera driver will be installed on the computer.
  3. Launch the Zoom app and click Settings (gear icon) > Video.
  4. Select the USB camera from the pulldown.

The camera used in the Zoom conference is now set to the USB camera.

External camera settings and advanced operations may require the attached app

If you want to make detailed settings or perform operations such as screen zoom with an external camera, you may need to install a dedicated app. For details, check the website of the manufacturer of the USB camera you are using.

Use your smartphone camera as an external camera

Most modern smartphone cameras have high image quality and high performance. Have you ever wanted to use this high-performance camera for video conferencing?

With the app, you can connect your smartphone to your computer as a webcam, and you can use it as a camera for Zoom.

Various applications have been released for using the smartphone camera as a web camera, but the following two are particularly famous.
