The Xiaomi Outdoor Camera CW400 allows for real-time two-way voice calls, enabling you to listen to and communicate with people near the camera.
If the voice is muted or unclear during voice calls, please refer to the following troubleshooting steps:
1. Make sure both Mi Home app and the firmware of the camera are the latest version;
2. Poor network connectivity can affect the audio quality during voice calls. Make sure both the smartphone for the call and the camera are connected to a stable Wi-Fi network;
3. If there is no sound on the smartphone, check whether the Mi Home app has been granted permission to access the microphone on your device;
4. Verify that the volume on the smartphone is turned up and not set to mute;
5. If possible, try making voice calls using different devices to see if the issue persists. This can help determine whether the issue lies with the camera or the smartphone;
6. As a last resort, reset the camera to its factory settings.
