Why does echo occur during voice calls of the Xiaomi Outdoor Camera AW300?

If you experience echo during two-way voice calls on the Xiaomi Outdoor Camera AW300, it’s due to the close proximity between the camera and your phone. Echoes occur when the microphone on one device picks up sound from the other, causing a feedback loop.
To reduce this phenomenon, please consider the following factors:
1. Keep your phone at least 10 meters (or about 30 feet) away from the camera during the call. The closer the devices are, the more likely they are to pick up and amplify each other’s sound, leading to an echo effect;
2. Echo can also be worsened by environmental factors, such as loud surroundings or a poorly designed room. Ensure the area is relatively quiet to improve call quality.
