Motion detection in embedded DVR using MPEG isn't very easy as you have to go through many trials and errors to adjust camera motions. In addtion not every camera have the same hardware to run your code... To make thinks easier Flash is the easiest tool to use as a GUI to display video. In addition a 56K modem can easily capture motion using Flash in contract with using any other video rendering tool. I have created a tool called FlashIPX which can render your video camera, at home or at work, as a tool to use as a video surveillance using motion detection technology using C, C++, ASM as an API to use with either Java or .NET to create your own video surveillance application using Flash for the web or mobile operating systems.
The code is in testing phase and should be available soon.
