Cameras Don't Show Up In Zoneminder

Hi all.

Trying to set up a video surveillance system with Zoneminder on Ubuntu Jaunty. I am using a Logitech Quickcam for this. The camera works with Ubuntu, when I run XawTV I can see everything clear as day. When I try to get the camera to show up in Zoneminder I get no picture. I have tried a bunch of different device format and color combinations and still cannot get it to show up. If anyone has any experience with Zoneminder or has had this problem please help! Thanks in advance.

If a moderator feels that this belongs in the hardware section or somewhere else please feel free to move it wherever I am likely to get the best answers. Thanks a lot.

from the main zoneminder console, under the option 'source'

select the link. then check settings on general and source tab.
mine are like so:

general -

name -> cameraname
sourcetype ->remote (yours would be local if the cam is locally attached)
function -> modetect
linkedmonitors -> cameraname
ref image blend %ge -> 7

source -
protocol -> http
method -> simple
remote hostname -> user: password@remote.hostname
port -> port
width -> 640
height -> 480
orientation -> normal

bear in mind im using an ip camera, but your settings should look similar.

also please find where you logs are

zoneminder console -> options -> paths

tail -f these logs whilst restarting zm

let me knw how it goes

NB - the section where i entered remote hostname, i had to put a space after user: - only in the post so i didnt get that smiley icon. if your cam uses login details, you would enter no space between user: password

Thanks for the reply, I've been rather busy today I hope to try this and get back to you by the end of today though.

OK, my setup is local, I do have the camera plugged directly into the computer at the moment.

The log file that caught my attention the most was zmdc.log which revealed this:

10/05/2009 16:22:32.055844 zmdc[22302].INF [Starting pending process, zmc -d /dev/video0]
10/05/2009 16:22:32.057722 zmdc[22302].INF ['zmc -d /dev/video0' starting at 09/10/05 16:22:32, pid = 19336]
10/05/2009 16:22:32.099510 zmdc[22302].ERR ['zmc -d /dev/video0' exited abnormally, exit status 6]

To me, at least, it looks like it tried to start the camera and failed but I couldn't find much on what exit status 6 is yet. I shall continue hunting. Thanks for whatever information you can give and have given.

EDIT: After googling exit status 6, every forum topic I could find on it was inconclusive as to the problem.

I tried changing the device format and color multiple times, even tried gray as was recommended somewhere else and that did not work either.

looks like your camera isnt being detected.
can you confirm that the camera is actually on /dev/video0?
dmesg should tell this.

what is your output from

Code:

zmu -q -d /dev/video0 -v

i would be interested in seeing your settings.. as i described mine above..

OK when I try that command I get:

Code:

Error, username and password or auth string must be applied

Now for the settings, in the General tab I have:

Code:

Name:                      Monitor-1

Source Type:                Local

Function:                  Modect

Enabled:                    Yes

Linked Monitors:            Monitor-1

Max FPS:                    None

Alarm Max FPS:              None

Reference Image Blend %ge:  7

Triggers:                  None Available

And then in the Source tab I have:

Code:

Device Path:                /dev/video0

Capture Method:            Video for Linux 2

Device Channel:            0

Device Format:              PAL

Capture Palette:            RGB24

Capture Width:              320

Capture Height:            240

Preserve Aspect Ratio:      No

Orientation:                Normal

I have tried a whole load of different device formats and capture palettes and it hasn't made any difference so I've left it at that one because it seems to be the most common from other Zoneminder users.

I am almost positive the camera is /dev/video0 because I did:

Code:

ls /dev/video*

That gave me /dev/video0 only, I only have the one camera plugged in.

EDIT: Thanks for all your help by the way.

I also ran:

Code:

xawtv /dev/video0

and it worked, XawTV started up with the camera.

must be some settings then

run

Code:

zmu -q -d /dev/video0 -U user --password password

also whilst doing any restarts, be sure to be tailing the logs in the background.

something like

Code:

tail -f /path/to/zmlogs &

should always be running in the background for these purposes so you can see any new events logged

Perhaps this is a stupid question, not sure. There was a never a time to create a user and password during installation so is there a default administrator user and password for Zoneminder? If not how can I create a user and password after installation? Just for the sake of it I tried using the Apache username and password which did not work.

can be changed by clicking the options link.
also make sure the zone minder console is 'Running'

OK, admin/admin worked thanks for that, I ran

Code:

zmu -q -d /dev/video0 -U username -P password

and I got "error22" for the output, that is it.

Maybe this will help also. I ran "v4l-info" and this is what I got:

There was also some stuff for Linux version 1 but it didn't have much information and some wasn't available so I just pasted the Linux 2 stuff in.

Maybe this helps a little bit too. This is the debug log.

Device permissions?

Did you check the permissions on /dev/video0? I had to run 'sudo chmod 666 /dev/video0' to get my cameras to show up.

I'm new to Linux and Zoneminder and basically just followed the tutorial I found here: "Ubuntu 9.04 (Jaunty) desktop with graphical interface". Sorry, I can't post the link since I'm a new member.

I have a brand new Jaunty install (and update) and Zoneminder install using the Synaptic Package Manager. It won't surprise me if I run into more problems.
