On the webGUI navigate to "Utilities" / "Web Director".
Hi here
1. Allow display video on web Interface (IR remote only): System -> Admin Settings -> General Settings -> Security -> Security Settings -> (3-rd screen) -> Allow Video Display on Web
2. From Web: Utilities -> Web Director
Please take in mind that web director shows you a still picture refreshing every 5 (?, I don't remember exactly) seconds.
Hope this could help
Mike
