Yes the camera can be used as a webcam, I use it for this:

FTP upload in an interval only works with pictures and not with video (the setting "Interval" is only visible if mode "Picture only" is selected). See

If the camera is used as a surveillance camera, it can upload pictures and video to an FTP or send them by e-mail when motion is detected.
