To test a video conferencing system, run a short routine before important meetings: check the camera picture and framing, make a test call to confirm the microphone and speakers work, listen for echo from a second device, run a network speed test, and try sharing your screen. Teams, Zoom and Google Meet each have a built-in test call or preview for this.
Five-minute pre-meeting checklist
| Check | How | What good looks like |
|---|---|---|
| Camera | Open the camera preview | Faces in frame, in focus, not backlit |
| Microphone | Test call or level meter | Level moves when people speak from the far seats |
| Speakers | Test call playback | Clear at normal volume, no distortion |
| Echo | Join from a second device in another room | No echo of your own voice |
| Network | Speed test on the room's network | Stable upload and download, low jitter |
| Content share | Share a slide or document | Readable on the far end |
Platform test calls
Microsoft Teams (desktop): Settings > Devices > Make a test call. You record a short message and it plays back, with device status for mic, speaker, camera and network.
Microsoft Teams Rooms: Use the room's settings to confirm devices, then join a test meeting from a laptop in another room. See Teams Rooms troubleshooting.
Zoom: Go to zoom.us/test to join a test meeting, or use Settings > Audio > Test Speaker and Test Mic, and Settings > Video for a camera preview.
Google Meet: On the pre-join screen, use the "Check your audio and video" option to record and play back a short clip.
Testing the camera
- Open the preview and sit in the farthest seat. Check that faces are large enough.
- Turn on and off auto-framing to compare.
- Check lighting: no windows directly behind people, faces evenly lit. See conference room lighting levels.
- For PTZ cameras, recall each preset. See PTZ camera control.
Testing audio and echo
Echo is the most common complaint and the one you can't hear from inside the room.
- Join the meeting from the room system.
- Join the same meeting from a laptop or phone in a different room, with headphones.
- Speak from the far end of the room. You should hear it clearly on the second device.
- Speak into the second device. People in the room should hear it, and you should not hear yourself come back.
- If you do, make sure only one microphone and one speaker are active in the room, and see fix echo on a conference call.
Testing network quality
- Run a speed test from the room's network port, not your Wi-Fi.
- Watch for upload speed, packet loss and jitter, not just download.
- For room systems, check each platform's network requirements and firewall ports. See video conferencing bandwidth and Teams Rooms network requirements.
Testing content sharing
Share a slide with small text and a short video clip. Ask the far end whether the text is readable and the video is smooth. If you use HDMI or wireless sharing, test both. See Teams Rooms content sharing.
Build a room test routine
For shared rooms, put a monthly test on the calendar: one call from each room, the checklist above, and a note of firmware versions. Fix failures before the room's next big meeting. Our video conferencing problems guide covers the common causes.
If your rooms keep failing these checks, let us review the setup and suggest fixes.
