Talking to Network Cameras.

Does anyone have any idea where I could find out how to operate a D-Link
DCS-500W network camera fr5om software I have written. Further to this, if
it streams video on port 5003, how can i capture that using my software.

This is all way over my head so i just wanted to see if it is possible for
the time being, before i actually made any attempt.  The idea behind the
ability to  command the camera is to make use of its pan and tilt
capabilities.

Cheers

I'm doing something similar with an IQeye camera.  The first thing you
should do is determine the format in which it is streaming.  The camera
I use streams the images as JPEG data over port 80 using TCP/IP.  Your
may be the same, or it might use UDP.  For me, the stream itself is
structured using the MIME multipart/mixed format (server push) which you
can learn more about here:

If your documentation doesn't give specifics, you may be able to
determine the format by connecting and streaming some data to a file.
Then you can view the file in a text editor and look for readable text
that gives you clues about the structure of the stream.

Issuing commands to the cameraa is a separate matter.  You will need to
know what commands are used and how these commands are sent to the
camera.  For my camera, you need a telnet connection over which you can
issue simple text commands to control various aspects of the camera,
including the digital pan, tilt and zoom.
