1080 pan & tilt indoor camera beeping in use?

I got the camera a couple of days ago, to remotely observe my dog.
Very happy with it so far, and it seems to function as expected.
However, early this morning, whilst in the room with the camera, I noticed the camera making a repeated high pitched intermittent beeping noise, that sounds like an alarm or malfunction?
Had to turn it off for now, as the sound is penetrating and very unpleasant to my ear. My dog is blind, so her hearing is extra sensitive.
Help appreciated please.

Just updating to say my husband has resolved this. When he turned the camera back on to investigate, the noise started again.
Turns out the noise is ‘feedback’.
Have turned off the audio settings completely, as I wasn’t planning to use them anyway, so it’s no longer an issue.
