==== Misc Notes (Anyone care to categorize?) ====
Check zone.conf or zm.conf. Check that there are no bogus vesions of this file lying around. 
"nobody" doesn't have shell access, choose a different Apache alias like "httpd". 
zmdc.log or /var/log/messages log any errors. 
zm.sock file must be able to be created.

*/usr/local/etc/zm.conf must exist and what process owns it.
webuser and webgroup must be correct for apache to have ownership over zm.conf

==BIOS Issues==
Turning off ACPI power management in the BIOS may help alleviate some issues with ZoneMinder and capture hardware.

==Cambozola==
Cambozola is a Java plugin that decodes multipart JPEG streams. Mozilla-based browser have native support, so this plugin is for browsers like Internet Explorer that lack that support.

To install Cambozola for use in zm, Download the cambozola.jar file from the Downloads page or directly from the charliemouse website. If you download from charliemouse you will need to extract the one file (cambozola.jar) from the archive. Place cambozola.jar in the ZM root web directory (so if your web pages for ZM is installed at /var/www/html/zm the file should go there as well). Now all thats left to be done is to enable it in ZM goto options and under the web tab check that cambozola is enabled. In 1.25 you will find OPT_CAMBOZOLA under the '''Images''' tab. That's it, you're done.

* http://www.zoneminder.com/forums/viewtopic.php?t=6320

NOTE: If you find that the Cambozola applet loads in IE but the applet just displays the version # of Cambozola and the author's name (as opposed to seeing the streaming images), you may need to chmod your cambozola.jar:

$ sudo chmod 775 cambozola.jar

Once I did this, images started to stream for me.

In Ubuntu and other modern distributions you can install MySQL administrator GUI.

the default login is :- 
Server Hostname ---- localhost Username ---- Root Password ----- (Blank, no password)

In here, there is backup and restore functions. The backup can also be scheduled.

==== Delete Databases/Tables ====

==== Database Tricks/Tips ====
* My personal recommendation is to try converting your database over to INNODB tables.
** Researching the web I found this to be faster for larger tables (as events grow) and much more reliable.

<code>

yum install ffmpeg ffmpeg-devel
</code>
Place the devel stuff in /usr/include/ffmpeg
Now configure, make, make install

*After getting ffmpeg from CVS, do:
<code>./configure , make, make install, make installibs</code>

===Changes in ffmpeg again===
It would seem that ffmpeg has possibly changed things again, no real supprise there but it complicates building ZM.

So if you find when you make:

zm_mpeg.h:29:29: error: ffmpeg/avformat.h: No such file or directory

zm_mpeg.h:31:28: error: ffmpeg/swscale.h: No such file or directory

and whereis turns up:

/usr/include/libavformat/avformat.h

/usr/include/libswscale/swscale.h

The file you would need to change is zm_mpeg.h
and change the following two lines in that file:

#include <ffmpeg/avformat.h>
#include <ffmpeg/swscale.h>

Would have to be canged to:

#include <libavformat/avformat.h>
#include <libswscale/swscale.h>

==Increase Image size==
If you increase the image size on a camera, it's always best to close down any streams and restart ZM to make sure that all memory is released.

*All things are possible and the example someone posted a while back of detecting trucks and buses, but not cars, passing over a distant intersection is probably appropriate for you. What I would suggest you need are quite high pixel differences (indicating difference from the background) and pretty small counts of changed pixels or blob sizes. You might find it useful to turn on diagnostic images initially (and only for a while as they slow everything down a lot) which will output what ZM thinks the differences etc are are in the images.

==Zone Configurations and Fine Tunings==

The way I tuned my zones was to walk out in front of the camera and stand at the furthest distance from the camera where it would be useful to detect motion.

Then I replayed the footage and took a still of my standing away from the camera, loaded it into a photo editor and cropped the image to the size of my body.

Then looking at the image attibutes gave me the dimensions of the remaining space, I took the height and width and multiplied them to get a minumum number of changed pixels I wanted to cause an alarm.

I went into my zone and changed the units from percent to pixels. Then input the number I got from my previous calculation into the first two min fields, and subtracted 15% and put that number in the last minumum field.

* This section needs alot of work. Please contribute as much as you can!

Once you have Zoneminder up and running and all your cameras recording events, it then becomes important to fine tune your zones so that you record all of the events that are important to you, and just as important, NOT record events that are not important[http://www.gadgetsdotcom.com/ .]

There are many parameters to be adjusted. So many, in fact, that it is easy to change just a few parameters, and create a config that does not do what you want at all. It is all so confusing. Here, we will attempt to document some basic configs, and explain in some detail the effects that each parameter will have and how each parameter relates to the other parameters.

The Documentation page offers some help in understanding how these parameters are related and important. You can view the online documentation here:

Pico2000

2012-07-17T19:50:41Z

Ka1axy: /* ZoneMinder configuration */

== Introduction ==

PICO2000 is a cheap DVR card that works well with ZoneMinder.

=== Name origination ===

The name "PICO2000," though often used, is technically not correct. PICO2000 is the name of proprietary software that was bundled with this class of cards.

PICO2000 is available under many different brand names such as '''Star Imavision Video Capture''', '''Brooktree 848''', '''Brooktree 878'''. They are generally stated as '''PICO2000 compatible'''.

=== Specifications ===

PICO2000 is a quad camera input PCI card. The card uses a single Conexant 878A chip. In addition, some models have 1 audio input jack; it has not been tested with ZoneMinder.

* Compression: MPEG4
* Display Resolution: 352 x 240 (NTSC)
* Screen Display: 1/4/7/10/13/16 multi-view or full screen
* Multiple cards allowed as per your PCI slot allocation
* Minimum PC capability: Pentium III 800 MHz or equivalent
* 30 FPS (degrades as the channels are utilized; expect ~2 FPS with all four channels capturing)

=== Purchase information ===

A PICO2000 costs about US$5.00 in China with free shipping.

For the United States, ebay may be the best place to purchase a PICO2000. As of January of 2010, they are $30 each (including shipping from China). An ebay search for "PICO CCTV" will return results.

== Linux driver ==

Linux kernels after 2.6.2x appear to have the driver for this card bundled in. Further info can be found at [http://linux.bytesex.org/v4l2/bttv.html http://linux.bytesex.org/v4l2/bttv.html].

=== Linux configurations and experiments ===

In <tt>/etc/modprobe.conf</tt>

For one card:
options bttv card=77 tuner=4 radio=0 triton1=0 vsfx=0 autoload=0
For two cards:
options bttv card=77,77 tuner=4,4 radio=0,0 triton1=0 vsfx=0 autoload=0
And so on.

Also, if during bootup your system hangs for 5 minutes or more at "Setting clock (utc)":
options i2c-algo-bit bit_test=1
options bttv card=77 tuner=4 radio=0 triton1=0 vsfx=0 autoload=0
The order of the lines is important.

In Ubuntu 12.04 server, <tt>/etc/modprobe.conf</tt> is gone, so you need to create a config file in <tt>/etc/modprobe.d/</tt>:
* call it bttv.conf (the name doesn't really matter), and it contains:

alias char-major-81-0 bttv
options bttv card=77 pll=1

== ZoneMinder configuration ==

Settings under source >> source >> general...

The following settings depend on your camera. Check your camera's specification sheet (try the suggested starting values in brackets):

* Device format [NTSC, PAL]
* Capture pallet [GREY]
* Dimensions [X=320, Y=240]

When you have multiple cameras sharing one Pico card, you may have issues where:

* An image from one camera shows up on more than one input
* Blank images on certain inputs
* Mixed images between inputs.

The reported solution for these problems has varied. You may want to try each of the following options one at a time. Remember to restart ZoneMinder after each change.

* Disable V4L_MULTI_BUFFER (found in options >> config)
* Change CAPTURES_PER_FRAME to a value such as 2 or 4 (found in options >> config)
* Use Video For Linux version 1 for each input (found in source >> source >> capture method)
* In ZoneMinder 1.25, I had to use V4L2 to get it to work

== Chip history ==

The Conexant Fusion 878A is the newer version of the Brooktree Bt878A. The Brooktree Bt878A is the successor to the Bt848.

Video capture software supporting Bt878A that is not designed for CCTV will likely only allow you to access one camera port at a time.

Settings under source >> source >> general...

The following settings depend on your camera. Check your camera's specification sheet:

* Device format
* Capture pallet
* Dimensions

When you have multiple cameras sharing one Pico card, you may have issues where:

* An image from one camera shows up on more than one input
* Blank images on certain inputs
* Mixed images between inputs.

The reported solution for these problems has varied. You may want to try each of the following options one at a time. Remember to restart ZoneMinder after each change.

* Disable V4L_MULTI_BUFFER (found in options >> config)
* Change CAPTURES_PER_FRAME to a value such as 2 or 4 (found in options >> config)
* Use Video For Linux version 1 for each input (found in source >> source >> capture method)
* In ZoneMinder 1.25, I had to use v4l2 to get it to work

== Chip history ==

The Conexant Fusion 878A is the newer version of the Brooktree Bt878A. The Brooktree Bt878A is the successor to the Bt848.

Video capture software supporting Bt878A that is not designed for CCTV will likely only allow you to access one camera port at a time.

Ka1axy: /* Linux configurations and experiments */

== Introduction ==

PICO2000 is a cheap DVR card that works well with ZoneMinder.

=== Name origination ===

The name "PICO2000," though often used, is technically not correct. PICO2000 is the name of proprietary software that was bundled with this class of cards.

PICO2000 is available under many different brand names such as '''Star Imavision Video Capture''', '''Brooktree 848''', '''Brooktree 878'''. They are generally stated as '''PICO2000 compatible'''.

=== Specifications ===

PICO2000 is a quad camera input PCI card. The card uses a single Conexant 878A chip. In addition, some models have 1 audio input jack; it has not been tested with ZoneMinder.

* Compression: MPEG4
* Display Resolution: 352 x 240 (NTSC)
* Screen Display: 1/4/7/10/13/16 multi-view or full screen
* Multiple cards allowed as per your PCI slot allocation
* Minimum PC capability: Pentium III 800 MHz or equivalent
* 30 FPS (degrades as the channels are utilized; expect ~2 FPS with all four channels capturing)

=== Purchase information ===

A PICO2000 costs about US$5.00 in China with free shipping.

For the United States, ebay may be the best place to purchase a PICO2000. As of January of 2010, they are $30 each (including shipping from China). An ebay search for "PICO CCTV" will return results.

== Linux driver ==

Linux kernels after 2.6.2x appear to have the driver for this card bundled in. Further info can be found at [http://linux.bytesex.org/v4l2/bttv.html http://linux.bytesex.org/v4l2/bttv.html].
