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:

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 (missing 12 months/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
