TrafficCam

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.

Tasks:

• upgrade Stewie's HDD
• stop webcam cron jobs
• unmount weather cam from roof
• prepare green pelican case
• prepare pmp1
• prepare wifi antenna
• assembly gear
• configure software
• deploy functional traffic cam unit

Possible technologies:

• Technologic Systems single-board computer
• WiFi interface with directional antenna
• DRS1000 Delta speed sensor
• Axis weatherproof camera
• Weatherproof case
• Mounting pole
• Step ladder
• Rope
• Power Source
• Large IDE HDD (750GB / 1TB)

Image volume calculation:

• 60 seconds/minute x 60 minutes/hour x 24 hours/day x 7 days/week x 4.5 weeks/month x 12 months/year = 32,659,200 seconds/year
• 1 frame/second x 20 KB/frame x 32,659,200 seconds/year = 653,184,000 KB/year or 637,875 MB/year or 623 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
