Hi,  
Thank you for reaching out and sharing your concerns regarding your camera. We take your data security very seriously, and for your concerns, please provide more information for further analysis.

1. Did you hear the sound content coming from the camera? Our cameras have some built-in voice prompts. It may be due to your settings or operations that caused the camera to issue a built-in voice prompt.

2. Tapo cameras support two-way audio, which allows users to communicate with people near the camera using the 'Talk' and 'Voice Call' features in the Tapo app. If someone else can speak to you through the camera, it indicates they have access to the camera's audio features, possibly via a shared account or device. You can follow the steps below to check whether your Tapo account or camera has been shared with others. 
  a. Go to the Tapo app > Me > View Account > Login Security > Login Activity to see if there are any unfamiliar devices or users.
  b. Also, check device sharing in the Tapo app under Me > Device Sharing.

3. If your camera is connected to third-party devices (such as Alexa Echo, Google Home, Chromecast, or ONVIF clients), disconnect them to ensure only authorized users have access.

Below are some security recommendations:
  1. Please refer to the following instructions to stop sharing your camera with others.

  2. Refer to the following instructions to change the password of your TP-Link account regularly.
