Camera not detected or not showing in Teams/Zoom

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.
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).
- Use wired Ethernet rather than Wi-Fi, and check the switch port for errors.
- 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.
