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 - Consider the AXIS 211, http://www.axis.com/products/cam_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 HDDstop webcam cron jobsunmount weather cam from roofprepare green pelican caseprepare pmp1prepare wifi antennamount cam in enclosure on Dennis roofupdate cacti hdd monitoringconfigure stewie BIOSdisconnect cam in closetrename new HDD on stewie- timed charging from 110VAC for cam battery (need a timer)
- capture an MPG-4 @ 1 FPS and stream to stewie via pmp1 port 80
- install ipchains on the pmp
- ask for the pmp1's EC WiFi IP to be available from off-campus
- 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
