1. Don‘t turn on the speaker and microphone simultaneously because one-way audio can work better than two.
2. Please test microphone and speaker when phone and camera are not in the same network area. In other words, the phone and camera are not connected to the same wifi.
3. Default volume of speaker and microphone are set to the highest. Adjust the volume to reduce extra noise.
