I have not used that. Honestly it looks a lot like something I might have created myself if I hadn't found
Blue Iris.
Back in 2007 or 2008 I built a similar (but much less featured) motion detection program using the same motion detection software they did. It was never anything worthy of public release, but I still use it today in a few locations where a full Blue Iris license is not worth the cost. So I can appreciate the amount of work that has surely gone into trackrcam. Based on the History page it is a fairly active project.
However, considering I did not try the demo and can only make assumptions from the web page, I see quite a few serious limitations.
1. No mention of a web interface, or any remote viewing capabilities at all. I bet you are expected to log in with Teamviewer for remote viewing.
2. No mention of video format support. The history does mention FFMPEG but only in the context of compressing recordings, so I bet it can't consume anything but a jpeg-based video source.
I can't stress enough how much of a limitation this is, with today's cameras.
And this one I am sure about:
3. It isn't free; it costs $30 and the only thing it has over Blue Iris is motion tracking for what is no-doubt a small set of PTZ cameras.
