I wouldn't use reiserfs or reiser4. The original lead developer (Hans Reiser) has been jailed for murder and it is uncertain what development is now taking place with it. There are a couple of things you can do to improve performance. If you have large numbers of events then you should consider sett...

The down right graphic for pan/tilt control (located in ZM_PATH_WEB/skins/classic/graphics/arrow-dr.gif) is corrupted. As a result Firefox 4.0 doesn't display it.

Hello, I'm using ZoneMinder 1.24.2-3 on Ubuntu 10.04 x64 and I seem to be missing the Down Right Button control using Firefox 4.0. I'm almost certain this is web browser related because all the buttons appear when using Internet Exploder. Has anyone else experienced this and is there a solution? Th...

Have a look at this post http://www.zoneminder.com/forums/viewtopic.php?f=14&t=14295 It might give you some ideas. Stop zoneminder and anything else using the video device. Unload the bttv driver (sudo modprobe -r bttv) Reload the bttv driver (sudo modprobe bttv) Get the kernel messages (sudo dm...

Run GUVCViewer
Find out what the process id is for GUVCViewer.
Type the following command: where pid is the process id for GUVCViewer
This will list every device and file GUVCViewer has open. You should be able to see the video device from this.

It sounds like your disk is pretty heavily used (continuous record, multiple monitors etc) so it might be that the disk has been corrupted. you could try forcing an fsck of the disk. This should fix any disk corruption.

Solved: read/write permissions for Zoneminder. When you restart your Linux, /dev/video0 is "mounted" by root, and ZM cannot access it. You have to change the permissions to "www-data", the ZM user. I'm looking for some help in how to change permissions when booting (auto). You m...

The zoneminder code builds the sql statement in a buffer of a fixed size. When you have more than about 120 pre event images the buffer fills up and the remaining part of the sql statement is not added. As a result when it tries to execute the sql you get the "You have an error in your SQL synt...

zmaudit is controlled via the options->system menu. Look for RUN_AUDIT and AUDIT_CHECK_INTERVAL items.

You need to ensure that when you bring the computer back up it does not start the zoneminder processes otherwise it will start deleting again.

If there is still time then kill the zmaudit process. My guess is that you changed the setting for where the event images are stored (DIR_EVENTS) and zmaudit then ran and deleted all the event entries from the database because it could not find the events. You then changed it back and zmaudit starte...

The path to the export directory is hard coded into the php code. Look for the directory /usr/share/zoneminder/temp which is where it will store the files to be exported.

Any errors will appear in the apache error log file

Check the permissions on the temp directory. It must be writable by whatever user is running the http processes (wwrun on my system). If you are really desperate you could try changing the directory permissions to 777. Also, are you sure you are looking in the correct directory? On mine the temporar...

Options -> Config
Tick the "CREATE_ANALYSIS_IMAGES" box.

First, details of my setup. I have an RS232 to RS485 converter on the server running ZM. From this there is a pair of wires running to the first camera and then from the first camera to the second camera etc. This all works okay and I can control all the cameras. The problem I'm having is that I rec...
