I have a streaming web-camera in my office, it is a proprietary consumer electronics product, I did not build it, and I have a somewhat limited access to programing its underlying hardware.

The stream is at (http://someIP/videostream.cgi?user=z&...)

UPDATE: The camera is a FOSSCAM F18910W

and is formated as a series of jpegs. is there any way I can have OpenCV read a network stream? how would I set that up?

Videocapture is able to read the stream if it receives the proper string. What is the camera manufacturer/model? My suggestion is to visit this page, search for your camera model, and see if you can find that proper url. As your camera seems to be publicly accessible, I can take a look (if you give the model, of course)

the listing to the camera, I changed, its a limited user any how.

...follow this small sample

int main(int, char**)
{
    Mat frame;
    string url ="YOUR_URL"; // e.g. "http://someIP/videostream.cgi?user=xyz&pwd=some_pwd"
    VideoCapture cap(url);
    if (cap.isOpened()==false) {cout << "ERRROR!";return 1;}
    while(1)
    {
        cap >> frame;
        if(frame.empty()) {cout << "ERRROR!";return 1;}
        imshow ("Live",frame);
        if waykey(5)>0 break;
    }
    return 0;
}
