Gear to record video of the pedestrian crossing and the speed of Eastbound traffic in front of Earlham on National Road West.
Contents
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.
Shopping
- directional wifi antenna / Newegg url
- comes with N-Type, RP-SMA and RP-TNC connectors
- We will definitely need 2 or 3 of these MC to RP-SMA Adaptors/Cables (example)
- Also, we will need at least 10ft RP-SMA extension cable (male to female)
- 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:
Current battery and charge controller:
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 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 stewieask for the pmp1's EC WiFi IP to be available from off-campuslog power up for pmp and cam using croncontrol wifi up/down on bootcamouflage / paint bright colored gear- redo camera interface to be customized for this project
- measure power consumption of unit
- capture an MPG-4 @ 1 FPS and stream to stewie via pmp1 port 80
- install ipchains on the pmp
- 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
