Interesting... Experienced this EXACT same beep today. Same pitch, same cadence in my one year old 2021 Toyota GR Supra today...however, it has no dash cam. Persisted through multiple restarts and complete shut downs (continued beeping while car was off), driving and stops. Had no accompanying error messages in the message center or any trouble lights. Finally stopped on its own after something like 5-8 minutes of non stop beeping.
