Hello   @cgentil 

Thank you for reporting the case with us. 

Can you attach the video clip of the noise, or share the video shared link using Google Drive; OneDrive etc. 

May I know do you use the Video Call or Talk feature and at the end of the conversation there is some noise? 

Is this the replacement Tapo C210 camera or a different camera? 

Thanks.

Hello   @cgentil 

In case that sound is the sound feedback from the phone sound or echo, can you put your phone far away from the camera and test again? 

If the sound is from camera, you may need to get someome to use the Talk feature in another room, and another person sit beside the camera and see if there is still similar sound. 

  Hello @cgentil 

Wile testing in the lab, there is a very small sound when you turn On/Off the Mic function on the camera, while in the test room background sound, I can barely hear it unless we come close to the cam or in a very quiet environment. 

You may test if Disabling/ Enabling the Mic on the left side could reproduce the sound, if so, this could be the sound turning on /off the speaker.

This should be a common behavior on the camera instead of an issue with the cam, only that the sound can be noticeable when the camera is a very quiet environment.
