You can get RTSP URL from your camera directly. It is usually accessible from the local network only.
CameraFTP currently does not offer RTSP, instead, we offer browser-based camera viewer that can be embedded into your own web page. You can also use our API to get the last camera image(s) and automatically refresh it. For more detailed info, please visit:

CameraFTP supports FTPS, SFTP and FTP. You can use the standard FTPS/SFTP/FTP protocol to download the recorded footage.
