Trigger beep on the camera when someone enters the motion zone.

Hi, Is it possible for the camera to trigger a beep when someone sets off the motion zone? if not, how do i request a feature? I have signs on my garages “your on CCTV” but still people do not realise and urinate or smoke stuff or dump rubbish in the drive way… I could avoid a lot of confrontation with people if they just knew that they are being recorded!
