Gear to record video of the pedestrian crossing and the speed of Eastbound traffic in front of Earlham on National Road West.

To do (ordered):

  • Test-drive current Axis camera "in-situ" on the wind geny's tripod. Use the PMP1 for the interface with the directional WiFi antenna. Location is likely to be the shrubbery near the East side of the entrance.
  • Research all-in-one systems, see Alan's email.
  • Research discrete speed sensors, pay close attention to the interface and data stream.

Possible technologies:

  • Technologic Systems single-board computer
  • WiFi interface with directional antenna
  • DRS1000 Delta speed sensor
  • Axis weatherproof camera
  • Weatherproof case
  • Mounting pole

Image volume calculation:

  • 60 seconds/minute x 60 minutes/hour x 24 hours/day x 7 days/week x 4.5 weeks/month = 2,721,600 seconds/year
  • 1 frame/second x 20 KB/frame x 2,721,600 seconds/year = 54,432,000 KB/year or 53,156 MB/year or 52 GB/year

Software architecture:

  • Cache 2 minutes locally
  • Use infobomb stack to transfer and append to current day's movie
  • 4a-3:59a movies, sync with infobomb and roll-over, simple trac or fancydir listing by year-month

Questions for Doug:

  • Interface - 1 second frames, manual video review, automated video review, speed/video correlation,
  • Overall duration, 1 year?
  • Better density
