Stick Up Cam Recordings Have a High Pitch Whine

Hello. One of our Stick Up Cams has a high-pitched whine recorded with every video. There are no sounds coming from the camera and no sounds in the area around the camera, so it’s something internal that is causing the whine to appear on the videos. Is there any way to correct an issue like this, or how do we troubleshoot why this sound is recording with each video and covering up any audio that is happening in the area that the camera is recording? Thanks!
