@VorlonFrog ,
Along with what
@concord said about http URLs from BI, below is a more extensive list, courtesy of BI's Help topic, "The Web Server". Note that you can specify size and quality of the snapshot and pull raw H.264 streams and MJPG streams as well.
One of my BI cams is actually a raw H.64 stream from another BI machine at a tanning salon 15 miles away (in the lobby, of course!)
