Camera not detected or not showing in Teams/Zoom
- Check that the meeting app has the right camera selected (Settings → Devices in Teams, Settings → Video in Zoom).
- Plug the USB cable straight into the computer, not a hub or dock, and try the cable that came in the box.
- Close any other app that may be using the camera, then restart the meeting app.
- Restart the VC520 Pro3 by unplugging power for 30 seconds.
- Update the device firmware and the computer's meeting app.
Picture is blurry, dark or badly framed
- Clean the lens with a dry microfiber cloth.
- Make sure auto-framing or speaker tracking is turned on in AVer's app or the device settings.
- Light faces from the front; avoid a bright window behind people.
- Check the camera is at roughly eye level and centered on the room.
No sound or people can't hear you
- Check the device isn't muted (look for a red mute light).
- In the meeting app, select the VC520 Pro3 as both microphone and speaker.
- Check the volume on the device and on the computer.
- Move laptops and their fans away from the microphones.
Echo or feedback
- Make sure only one microphone and one speaker are active in the room: mute laptops that also joined the meeting.
- Don't run the room's audio through both the device and the TV speakers at the same time.
- Hard, bare rooms reflect sound. Rugs, curtains or acoustic panels reduce echo a lot.
- Update firmware: echo cancellation improvements often come in updates.
Keeps disconnecting or drops out
- Use the original cable and a direct port on the computer; long or cheap USB extensions cause dropouts.
- Turn off USB power saving on the computer (Windows: Device Manager → USB Root Hub → Power Management).
- Update firmware and the meeting app.
Won't turn on or status light is red/blinking
- Check the power adapter is the original one and firmly connected, and try another outlet.
- Unplug for 30 seconds and power it back on.
- Check the status light meaning in the user guide; a blinking light during startup or updates is often normal.
- If it never finishes starting, contact the manufacturer's support for a recovery.
