I just bought a LogiLink IP camera and wanted to get the pictures directly from a plain URL, but that was somehow not documented. After a while I figured a few URLs out which you could use:

• for MJPEG: http://your-ipcam-url/cgi-bin/guest/Video.cgi?media=MJPEG
• for JPEG Snapshot: http://your-ipcam-url/cgi-bin/guest/Video.cgi?media=JPEG

• for H264 (I don't use that, but it seems that there is some content available) http://your-ipcam-url/cgi-bin/guest/Video.cgi?media=H264
• for MPEG4 (I don't use that, but it seems that there is some content available): http://your-ipcam-url/cgi-bin/guest/Video.cgi?media=MPEG4
• standard RTSP streaming: rtsp://your-ipcam-url/live/h264
  

Have fun!
