Problem with no camera image displayed

easypea · Post by **easypea** » Mon Sep 04, 2006 11:02 pm

Hello All:
I'm a new ZM user - just installed it from the latest Live CD. I have two D-Link DCS-900 cameras attached to the system (yes I know they're miserable but they were cheap

for me to test with). I've looked through the archives and I've found various posts about these cameras and how to get video off them. I have their path set to video.cgi. I can set the cameras to Motion REcord and they will record (A file is created and I can use ZM to convert it to wmv and then view it). But the problem is I never get any images in window monitor (when you click on the camera name). In firefox I just get the torn page in the upper left hand corner - in IE I get the Cambozola message and then something like "No content..." after that - never any images. The only hint I see in the logs (/var/log/zm) is that the zmc process repeatedly dies and restarts (zmc -m 2 crashed signal

Any help is appreciated.

Thanks

i think you might need to turn on reg exp and use http 1.0 fot these cams mate but have never used them

James:
I've have done that as well: I put /video.cgi in the path and turned on the Regular expression matching as well as setting HTTP to 1.0. When I do that, cpu usage goes through the roof and it starts recording furiously. However, still no display of video.....

can you post your logs?

James, easypea,

Is this not the same issue that I am reporting in another thread on this list? I do not mean to hijack this thread, but as easypea and I appear to be seeing the same issue, hopefully the following info is helpful.

My apache2 error_log on SUSE10.1 says:
script not found or unable to stat: /srv/www/htdocs/nph-zms, referer: http://localhost/zm/zm.php?view=watchfe ... 0&control=

Why is zm.php looking in /srv/www/htdocs rather than in /srv/www/cgi-bin/zm?
And the monitor is blank, although clicking the Zone button produces a frame.

After make uninstall and re-installing configured as:
--with-webdir=/srv/www/htdocs/zm
--with-cgidir=/srv/www/cgi-bin/zm

I have /usr/local/etc/zm.conf showing:
# Path to ZoneMinder web files
ZM_PATH_WEB=/srv/www/htdocs/zm

# Path to ZoneMinder cgi files
ZM_PATH_CGI=/srv/www/cgi-bin/zm

As expected, nph-zms got placed in /srv/www/cgi-bin/zm by the install.

James,
Are you saying that you see an error in the configure commandline that I have posted?

Thanks James. Right on.
At the ZM console, in Options, Paths, ZM_PATH_ZMS I changed the existing value of "/cgi-bin/nph-zms" to "/cgi-bin/zm/nph-zms". That fixed it.

I wonder why the setting did not correctly reflect my build configure commandline and the ZM_PATH_CGI value in /usr/local/etc/zm.conf ? I guess they are different variables and the one does not read in from the other.

Thank you for your help, James.

no pros, not sure but i think its a different setting. You configure line tells the app where to install stuff. The paths in config tells zm where to get them from. Maybe Phil could answer when he pops in, I cant im afraid

Sorry - I just got back to a computer - no worries about hijacking the thread here!

Here are a couple of lines from /var/log/httpd/access_log:

easypea,

Have you studied the troubleshooting section of the documentation?

Does your camera work in xawtv?

-Robert

easypea · Post by **easypea** » Wed Sep 06, 2006 12:15 am

Robert:
Yes, I have looked into the troubleshooting section. I have not however been able to get xawtv to work at all...ignoring the camera... However, I know the camera is working because zm is recording video. Look back up in my original post and you'll see that I can use the video - convert (after clicking on a camera name and then clicking on an event - then Video - then Generate Video) to generate and look at video using this function. So the camera is recording - it just won't display in the view window for some reason.

O.K. Everyone:

First off - thanks for all the replies - I appreciate it!

I did some more troubleshooting on my own and it appears the problem is somehow related to the cambozola.jar usage. In the options I turned off the check box that says to use that file. I then went to a Windows box and opened up zm and clicked on one of my monitors. I still had no display there, just a red x up in the corner. I then selected one of the events that ZM had previously recorded and VOILA the individual images appeared on the screen. So, is there maybe a permission problem on that .jar file or is there perhaps a bug?? It says its version 0.5 on the screen just before I get the 'no content' message over top of it. Or is the java file looking to get the images and somehow doesn't know where to look?

Hope this helps because I think I'm getting close!
