Upload camera recordings to S3

I got a Yi 1080p home camera that I hacked with a custom firmeware giving it ability to upload videos to an FTP server. But I’m looking for a solution to store the files on S3.

I looked at installing the official FTP add-on on the Pi running Hass and then mounting the FTP destination folder with S3 using something like S3FS https://github.com/s3fs-fuse/s3fs-fuse

But it requires installing some packages on the Pi and I’m not sure how to gain root access on the PI in order to do that.

Is there an easier way and I’m overcomplicating it ? I’ve only been running Hass for a few days, so please advise.
