Camera beeping

I’ve had my indoor roku camera for at least 4 months and tonight, (time of post) my fiancé has heard beeping coming through the camera loud. This has not occurred at all in the entire time I have had it or my sisters camera either. Has anyone else heard this?? I have a baby girl so I need to know it’s not someone hacking. If a team member could respond to this message, I can email the video clip where you can hear the sound. Thank you in advance!
