I did a presentation awhile ago at chipy.org about the webcam busyness
analysis software I have been working on at Pumping Station: One. It
allows the busyness information to be extracted from motion-jpeg streams
(either direct from cams or from zoneminder, if the cameras are USB and
you run zoneminder) in nice ways such as historical data with a web api,
and an IRC bot.
There is a video of the presentation and some further links (to the
github and the installation) on my blog here:
