Sound feedback in video with no relief

I’m getting a serious feedback that almost sounds like some kind of alarm but it’s not. I’m getting it in both of my cameras as well as my doorbell. I have adjusted the volume but it doesn’t make a difference. It gets louder and louder the longer I leave the video on.

Like live view? Are you close to the camera watching live?

Yes live view. Even with my camera all the way up in a top corner. It’s an echo that keeps echoing and getting worse with every echo.

This is feedback. Normal. Hit the little speaker icon to shut off the sound when your in front of a live camera.
