Black screen using remote IP camera

[johnmaher]

This is my first post and I believe I have followed all the appropriate steps before getting to this point. I really hope someone can help me.

I've installed zoneminder 1.24 via package on Ubuntu 10.04 server and followed all of the instructions here: http://www.zoneminder.com/wiki/index.ph ... fmpeg,_etc.). In the interest of playing with different shared memory settings, I also used the script provided here http://www.zoneminder.com/forums/viewto ... ory#p72552.

I'm using Axis M32 network cameras and have disabled the need to authenticate to view the images. Using a browser I can access the cameras just fine. I've set them to 640x480 and have configured the monitor in zoneminder the same.

In zoneminder I've set the monitor to "remote" and "monitor". I've set the Remote Protocol to "HTTP" and the Remote Method to "Simple", although I've also tried various RTSP settings. I've set the source to the hostname (or IP; no difference).

Based on some suggestions in the forum I thought it was a CGI issue (and maybe it still is), but I've added ScriptAlias to the zoneminder.conf file in /etc/apache2/conf.d/zoneminder.conf, which is a symlink to /etc/zm/apache.conf.

Here's the /var/log/messages output when restarting zoneminder:

Seems fairly unexciting.
Here's the output when I click on the monitor name to view the image:

Code: Select all

Mar 22 10:36:41 scribe zms[7368]: WAR [Unable to store frame as shared memory invalid]

Certainly looks like shared memory is a problem, but I cannot think of any other actions to take regarding it.

So few people in the forums seem to be using network cameras, which seems (to me) to be more challenging. Maybe that's not an issue, but if you can help I would be most appreciative.

Thanks.

Apparently everything was configured properly except the Remote Host Path, which was figured out using the Presets link. I figured this out by following the instructions from "How to setup an axis 213 with pan tilt zoom" even though I do not have an Axis 213.
