Hi,
Can you share a video about the noise problem with us? For example, you can upload the video to your own cloud server(such as Google Drive), then generate a link and send it to me via private message.

What's the model number and OS version of your phone? Do you hear the same noise when watching the camera on a different phone?

Best Regards

Hi,
It seems there is noise in the environment from the video recording. Can you place the camera indoors, put it in a quiet environment, away from the electric devices, and then check if you can hear the same noise from the Live View page?

Best Regards
