This is about a particular Vantage DVR model, which model number I can't remember. It will probably apply to most other models.

Remote Access

The DVR can be accessed using a Microsoft Windows based program, or via the web interface. Vantage Viewer & Manual

Web Interface

The web interface is somewhat interesting, as it does not allow browsers other than Internet Explorer to connect. Video delivery is delivered using constantly refreshing images. This seems to be done in JavaScript, so I can't quite see why it wouldn't work on other browsers. I've managed to find a way of getting a live stream of images as long as the user is logged in, in the same browser session.

And so on...

Just keep hitting that refresh button, and you will get a live image. I suppose this could be done within an HTML page automatically in some JavaScript, but I'm still working on the login situation. I've tried using the XmlHttpRequest object to authenticate, in the hope that the DVR would then let me grab images, but this is not the case. My intentions are to create an iPhone web app, that allows the user to authenticate to the DVR, then be able to view the live video.
