Web Cam / Motion Detection
Hardware
| Manufacturer | Model | Misc |
|---|---|---|
| Logitech | QC Communicate STX | vend/prod from dmesg: 0x46d/0x8ad |
| NewPoint | 4-Port USB Hub | USB Version 1.X |
*NOTE* I tried a Kensington (model 33141) USB 2.0 hub that is backward compatible with 1.x and it didn't work.
Setup
- Make sure ipkg is updated:
ipkg update
- Install USB drivers:
ipkg install kmod-usb-core ipkg install kmod-usb-ohci ipkg install kmod-videodev reboot
- After rebooting, try plugging in the USB hub and you should get a message in dmesg at such:
hub.c: new USB device 01:02.0-1, assigned address 2 hub.c: USB hub found hub.c: 4 ports detected
- Install the spca driver (backed up in the wrt\cam folder):
wget http://pmeerw.net/openwrt/kmod-spca5xx_2.4.30+20060501-brcm-1_mipsel.ipk ipkg install kmod-spca5xx_2.4.30+20060501-brcm-1_mipsel.ipk insmod videodev insmod spca5xx
- Plug in the USB camera and you will get the following messags from dmesg:
hub.c: new USB device 01:02.0-1.4, assigned address 5 drivers/usb/spca5xx.c: USB SPCA5XX camera found. Logitech QC Communicate STX drivers/usb/spca5xx.c: [spca5xx_probe:8380] Camera type JPEG drivers/usb/zc3xx.h: [zc3xx_config:415] Find Sensor HV7131R(c) drivers/usb/spca5xx.c: [spca5xx_getcapability:2207] maxw 640 maxh 480 minw 176 minh 144
- To automatically do the "insmod", append to /etc/modules as such:
echo "videodev" >> /etc/modules
- Install motion and the jpeg library (backed up in the wrt\cam folder):
ipkg install http://naaa.de/programme/motion/libjpeg_6b-1_mipsel.ipk ipkg install http://naaa.de/programme/motion/motion_3.2.6-1_mipsel.ipk
*NOTE* Motion requires the "libpthread" package, but it should automatically pull it down from openwrt.org
- Push up the default config from the wrt\cam\motion_confs\single folder:
scp motion.conf root@192.168.0.222:/etc/
- You should be able to run motion now, by typing "motion -n". If you have firefox (or another mozilla based browser), you can point it to the IP:8081 as such:
http://192.168.0.22:8081
- Ctrl+C to get out of motion.
- Since I can't always use firefox, I install a java (yuck) applet (backed up in the wrt\cam folder) for streaming as such:
wget http://www.charliemouse.com/code/cambozola/cambozola-latest.tar.gz gunzip cambozola-latest.tar.gz tar xf cambozola-latest.tar.gz <--- I received a "tar: Invalid tar magic" message. It still works, but I should investigate later. mkdir /www/webcam/ mv cambozola-0.68/* /www/webcam cd /www/webcam/ vim example.html
*NOTE* Change http://localhost:2020 to your IP:PORT as such: http://192.168.0.222:8081
*NOTE* Change width / height as desired, I used 600x480.
mv example.html index.html
- Now you can run motion with either motion by itself for daemon mode, or with the -n for non-daemon mode.
- Point your IE browser to http://192.168.0.222/webcam and you should see your cam's image stream.
Tips and Tricks
For spcacat use spca5xx_lite.o (backed up in the wrt\cam folder):
- Needs the following packages:
ipkg install libgcc
- insmod spca5xx_lite.o
- ln -s /dev/v4l/video0 /dev/video0 <---Won't work with /dev/v41/video0
- spcacat -d /dev/video0 -s 640x480 -g -f jpg -p 3000 -o
Troubleshooting
Black Picture
The web cam stream is showing a black picture and nothing more.
Solution
Kill motion and re-start it and it should solve the issue.
