Hello,

I have a computer running Ubuntu server (11.04) with 4 generic usb cameras I purchased on ebay.
The computer runs Motion with no problems but I can't get ZoneMinder running (I'm trying to get zoneminder running with one camera first).
I installed zoneminder by typing:

Code: Select all

apt-get install zoneminder

.
I set permissions on /dev/video0 to 777.
when I type:

Code: Select all

zmu -d /dev/video0 -q -v

I get:

Video Device: /dev/video0

If I click "Probe" I get:

Can't parse command output 'd:/dev/video0|D:uvcvideo|C:USB 2.0 PC Camera|B:usb-0000:00:11.2-5|V:1.0.0|T:0x4000001|S|F:YUYV|B:640x480|I:1|i0:Camera 1|i0T:Camera|i0S:0|i0SP:1|i0SS:1|i0SC:1|i0HP:1'

I would appreciate it if someone could guide me through the process of getting it up and running.

Thanks.

Your should check your logs in /var/log/syslog to see what is exactly the error zoneminder is findind. Did you checked your shared memory settings?. Is one of the most common sources of problems when trying to see the image.

Read this post: http://www.zoneminder.com/forums/viewto ... 21&t=17595, it contains a script that should tell the proper settings for your zm system.

If does not work, post a extract of the log with the errors.

Hope it helps,

Have you tried changing 'dev/video' to 'dev/video0' as device for your camera in the gui-settings?

Whoops!

I changed it to /dev/video0 and now when I probe I get:

Unable to probe local cameras, status is '255'

Forget about probing, could you post the ERR output in the /var/log/syslog file?. Without any log, we could not know where the error come from!.

Read this post: viewtopic.php?f=21&t=17595, it contains a script that should tell the proper settings for your zm system.

Ran the script and increased my kernel.shmmax to the recommended amount and rebooted.
Here are the ERR from the syslog:
