Wiring
On the camera, there's a hacked-up PoE cable that does the following:
1 wht/org ethernet 2 org/wht ethernet 3 wht/grn ethernet 4 blu/wht GND, also Digital Input - 5 wht/blu Digital Input + 6 grn/wht ethernet 7 wht/brn Relay Output 8 brn/wht +12V, also Relay Input
This allows the camera to be positioned away from the door by running a single cable. Without this, you'd need one for power, one for network, AND one for the I/O pins. Using a single 24ga wire for power is suboptimal, but the camera doesn't draw much power, and it hasn't been an issue yet.
In the box above the door: Ethernet pins pass through to Ethernet input (into which is plugged the feed from the back of the space.) GND from power input goes to GND from camera, also to LED cathode and SSR negative. +12 from power input goes to +12 from camera, also to switch contact. Relay Output from camera goes to LED anode and SSR positive. Digtal Input + from camera goes to switch contact. SSR isn't currently connected; signals are on orange wires, shrinkwrapped to prevent shorts in the time being.
(To accommodate a future local OPEN sign, provision has been made for connecting the big solid-state relay, which can switch anything we could throw at it.)
Software
The most important part of all this! Camera documentation: [1]
Proof-of-concept batch file:
:top del getdi.cgi wget --user=port --password=port http://i3detroit.dyndns.org:5000/cgi-bin/getdi.cgi find "DI=L" <getdi.cgi echo %errorlevel% if %errorlevel% EQU 0 wget --user=port --password=port http://i3detroit.dyndns.org:5000/cgi-bin/setdo.cgi?do=l --output-document=NUL rem This turns the LED off when the switch is down. find "DI=H" <getdi.cgi echo %errorlevel% if %errorlevel% EQU 0 wget --user=port --password=port http://i3detroit.dyndns.org:5000/cgi-bin/setdo.cgi?do=h --output-document=NUL rem This turns the LED on when the switch is up. sleep 1 goto top
Updated batch file, this is the one currently running on nate's desktop at home:
echo off rem set currentstate=off set camerahost=i3detroit.dyndns.org:5000 set camerauser=port set camerapass=port set twitteruser=contact@i3detroit.com set twitterpass=redacted-from-wiki :begin del getdi.cgi wget --user=%camerauser% --password=%camerapass% --timeout=5 --tries=2 http://%camerahost%/cgi-bin/getdi.cgi find "DI=H" <getdi.cgi echo %errorlevel% if %errorlevel% EQU 0 goto itson find "DI=L" <getdi.cgi echo %errorlevel% if %errorlevel% EQU 0 goto itsoff :loop sleep 10 goto begin :itson echo It's on! wget --user=%camerauser% --password=%camerapass% --timeout=5 http://%camerahost%/cgi-bin/setdo.cgi?do=h --output-document=NUL if "%currentstate%" EQU "on" goto loop set currentstate=on echo Switch set to ON state, %time% %date% >> log rem wget --user=%twitteruser% --password=%twitterpass% --post-data="status=The space is OPEN FOR GUESTS as of %time%, please drop in!" http://twitter.com/statuses/update.xml --output-document=NUL del video.jpg wget --user=%camerauser% --password=%camerapass% --timeout=5 http://%camerahost%/cgi-bin/video.jpg curl --form username=%twitteruser% --form password=%twitterpass% --form media=@video.jpg --form-string "message=The space is OPEN FOR GUESTS, and here's who flipped the switch!
