    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.<br>
    <br>
    There is a video of the presentation and some further links (to the
    github and the installation) on my blog here:<br>

                      One of our members wrote a server back-end that
                      you can point the<br>
                      Linksys web cams at for off-site storage. It gets
                      FTP updates whenever<br>
                      one of the cameras detects motion, then stitches
                      the frames together<br>
                      into a flash player.<br>
                      <br>
                      He says he'll open-source it if there is interest.
                      He just doesn't<br>
                      have time to maintain it.<br>
                      <br>
                      Anyone interested in a first world-wide
                      hackerspace infrastructure project<br>
                      <br>
                      Regarding security and monitoring who is there, I
                      think the best<br>
                      approach is to combine a hardware-based
                      access/alarm board with a<br>
                      Linux server that monitors and ties in with video.
                       Being able to see<br>
                      who came/went, status of all of the doors (did
                      someone leave the front<br>
                      door unlocked?) and having an IP-based alarm
                      system that you don't<br>
                      have to pay for (we use an SMS call-out list)
                      really gives you the<br>
                      best of all worlds. Sensors and embedded hardware
                      for real-time<br>
                      operations, and video for auditing, verification
                      of alarms, and<br>
                      general "what's going on?" questions.<br>
                      <br>
