Is there any way to arm the ring camera automatically when outside the geofence?

Hi @user41615. There is no way to automatically change the Modes on your Doorbells or Cameras. Ring Alarm users can use the Mode Scheduling feature to automatically change the Mode at certain times, but users without an Alarm will not have this feature. Neighbors have requested this feature before, which you can find here. You’re welcome to add your feedback and vote to that request.
