    Our Goals:

    • record video from live events on campus
    • stream some of these videos to the web, either internally or externally with a password
    • Events
      • GPAC
      • Gym: vball basetball
      • Pool
      • Flagpole
      • Field (?)
    Technologies

    • Quicktime streaming server
    • podcast producer
    • podcast publisher (lion only)
    • security spy
    • wirestream
    • IP camera access
    Issues

    • QTSS
      • really clear
      • 2000+ users
      • recorded to disk
      • delay of 8 seconds
      • does not work with IP cameras
      • need a computer to send the stream from the camera
      • old technology
      • cheap
      • runs on elabx2.hpa.edu port 7070 and 80, over web or quicktime
      • can be saved as a stream.sdp (session description protocol) or .mov file (movie)
      • We tested this with a logitech VTC camera with included audio (noisy)
    • Podcast producer
      • video and audio captured on any mac/pc with web app
      • video captured locally, then sent to podcast producer server
      • podcast producer server can use Xgrid to harness power of many machines
      • may be useful for recording many class sessions daily
      • we own it
      • uses "workflows" meaning jobs sent to the server
      • Our server was elabx2.hpa.edu
      • processing delay could me minutes long
      • created a directory of movies (helpful for classes)
      • We tested this with a logitech VTC camera with included audio (noisy)
    • Podcast publisher
      • works only with lion (osx 10.7)
      • captures streams, audio, classroom lectures-could be very useful for classes
      • local processing, then either served locally or uploaded to a server
      • can also generate workflows as above
      • no delay, no server needed
      • we did upload to elabgreen.hpa.edu our test lion server (10.7)
      • We tested this with a logitech VTC camera with included audio (noisy)
      • Easiest to use
      • no live stream
    • Security spy
      • created for security cameras (IP cameras)
      • works with local usb camera, firewire, built in iSight cameras, IP cameras
      • streams to the web, no delay, makes recordings
      • to record, set camera to active mode
      • can be activated by motion or sound from the camera, or timed
      • has website
      • could be useful for stage hands, since no delay
      • camera only talks to one server, server talks to many (faster)
    • Wirestream
      • expensive ($500 for local version, $1000 for IP camera version)
      • streams to many
      • may be delayed
      • may record
      • many post-production (captions, voice over, watermarks)
    • Axis local camera
      • P1344 has zoom, remote focus, excellent video, expensive ($850)
      • IP camera
      • SD slot for recording videos and sound locally.
      • No built in movie recording to server (FTP) except via security spy
      • on screen triggers, record, snapshot
