Any participant in the same domain as the organizer can start and stop a recording from web or Hangouts Meet hardware (and Chromebox for Meetings), and all participants are notified that the meeting is being recorded.
Recordings are saved to a “Meet Recordings” folder in the Drive of the meeting owner and the recording is automatically attached to the Calendar event and shared with all invited guests in the same domain.
G Suite Enterprise edition admins can control whose meetings can be recorded at the organizational unit (OU) level. Within the Admin console, navigate to Apps > G Suite > Settings for Google Hangouts and select “Meet Settings.” Please note, this setting is on by default for all OUs. The setting is disabled for OUs that don’t have Drive enabled.
