One could always send video files to their own cloud. Nextcloud instance, sftp, rsync, etc. Rsyncd supports write-only. SFTP could write to an append-only directory (via xattrs) so even if they figure out how to use the ssh key, it won't matter. I also would never use the ring doorbell. Not only is that a security risk, but it also provides eyes on neighbors across the street. Legal, sure, but dodgy.
