They also support FTP without the SSH transport, and it's not FTPS either. Various IP cameras still support FTP as a way to write files out periodically; I use this to provide a "stream" from a camera (8 seconds per frame because reasons) to the world. Actual streaming via RTSP is also available, but I could never get a stable stream to a video host (like YT or Twitch) from the camera (partially because of a poor quality network connection that can't be upgraded easily). So, FTP + credentials -> walled off directory that's not under the web root -> PHP script in web root -> web browser.
