zoneminder, bt878 based video capture card and ubuntu hardy
Posted by ark, ,
I use zoneminder for my security cameras and with the new server (and new OS) I had to set up zoneminder again. I have a bt878 based card which worked great in the old setup.

Here's some tips to get things going:
xawtv -hwscan
Should be able to find your hardware, if not you're not going anywhere.
xawtv -device /dev/video0
or whatever hwscan told you, should show images, if not you need to look into that.

Once you have that all working the secret sauce is to add the user that runs your apache cgi scripts to the video group, so they can access /dev/video0
usermod  -a -G video www-data
now zoneminder should show your cameras.

My cameras are 320x240 NTSC

Other useful stuff:
lsmod | fgrep bt

My card was $20 from geeks.com, It has 4 inputs and I'm really happy with it.
