Am I making sense? I'm not sure. sftp merely provides ftp service tunnelled through ssh and gives access to ssh niceties like pubkey authentication. What specifically are you trying to do with ftp? If you want to be able to login remotely and pull images from the remote camera box, then certainly, sftp (or any number of other things) would work. If you set up pubkey authentication, then you're pretty secure at the remote end and there is nothing in the remote end that allows access to the local end. If you're trying to *push* images from the remote end to local, that's a different story. Pushing means you've got to run your authentication the other way and expose your local end to compromise from a compromised remote end. So, maybe you could lay out exactly what you want to have happen, again. also, if you are just tying to grab remote images every so often, and you have a web interface setup, you could just script wget to scrape the page every so often and save it locally. just a thought.
