The videos are not transferred to a cloud, but stored locally in the home base. When the memory is full, it is simply overwritten. This is sufficient for me, I don't have to keep track of who rang my doorbell a year ago. It's not a security camera but is actually only used to recognise who is at the door and has rung the bell. There is also no facial recognition, which is a shame, but it was not something I specifically wanted.
