Revision as of 16:05, 22 August 2008

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.
• directional wifi antenna
• AC to DC power supply (I think one of these will do)
  • SP-100-12 12V, 0~8.5A
  • SP-150-12 12V, 0~12.5A
  • SP-150-13.5 13.5V, 0~11.2A
  • SP-200-15 15V, 0~13.4A
  • SP-150-15 15V, 0~10A

current wifi card:

• orinoco gold classic
  • with connector

Current battery and charge controller:

• EP28-12 battery spec sheet
• Phocos CML10-2 10A,12/24V charge controller spec sheet

Possible technologies:

• Technologic Systems single-board computer
• WiFi interface with directional antenna
• DRS1000 Delta speed sensor
• Axis weatherproof camera - Consider the AXIS 211
• POE injector - homebrew with e.g. Linksys vs one with native 12VDC input capability
• Weatherproof case - Consider the AXIS ACH13HB, the datasheet is available at the same URL as the AXIS 211 camera (above) or the AXIS 290B
• Mounting pole
• Step ladder
• Rope
• Power Source
• Large IDE HDD (750GB / 1TB)

Tasks:

• upgrade Stewie's HDD
• stop webcam cron jobs
• unmount weather cam from roof
• prepare green pelican case
• prepare pmp1
• prepare wifi antenna
• mount cam in enclosure on Dennis roof
• update cacti hdd monitoring
• configure stewie BIOS
• disconnect cam in closet
• rename new HDD on stewie
• ask for the pmp1's EC WiFi IP to be available from off-campus
• timed charging from 110VAC for cam battery
• capture an MPG-4 @ 1 FPS and stream to stewie via pmp1 port 80
• install ipchains on the pmp
• log power up for pmp and cam using cron
• control wifi up/down on boot
• redo camera interface to be customized for this project
• camouflage / paint bright colored gear
• deploy functional traffic cam unit

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
