ZoneMinder can run in two modes. The simplest is an entirely
unauthenticated mode where anyone can access ZoneMinder and
perform all tasks. This is most suitable for installations
where the web server access is limited in other ways. The other
mode enables user accounts with varying sets of permissions.
Users must login or authenticate to access ZoneMinder and are

ZoneMinder can use two methods to authenticate users when
running in authenticated mode. The first is a builtin method
where ZoneMinder provides facilities for users to log in and
maintains track of their identity. The second method allows
interworking with other methods such as http basic
authentication which passes an independently authentication
'remote' user via http. In this case ZoneMinder would use the
supplied user without additional authentication provided such a
user is configured ion ZoneMinder.

When ZoneMinder is running in authenticated mode it can pass

There are two methods for doing this. This first is to use a
time limited hashed string which contains no direct username or
password details, the second method is to pass the username and
passwords around in plaintext. This method is not recommend
except where you do not have the md5 libraries available on
your system or you have a completely isolated system with no
external access. You can also switch off authentication
relaying if your system is isolated in other ways.

When ZoneMinder is running in hashed authenticated mode it can
optionally include the requesting IP address in the resultant
hash. This adds an extra level of security as only requests
from that address may use that authentication key. However in
some circumstances, such as access over mobile networks, the
requesting address can change for each request which will cause
most requests to fail. This option allows you to control
whether IP addresses are included in the authentication hash on
your system. If you experience intermitent problems with
authentication, switching this option off may help.

The normal process for logging into ZoneMinder is via the login
screen with username and password. In some circumstances it may
be desirable to allow access directly to one or more pages, for
instance from a third party application. If this option is
enabled then adding an 'auth' parameter to any request will
include a shortcut login bypassing the login screen, if not
already logged in. As authentication hashes are time and,
optionally, IP limited this can allow short-term access to
ZoneMinder screens from other web pages etc. In order to use
this the calling application will have to generate the
authentication hash itself and ensure it is valid. If you use
this option you should ensure that you have modified the
ZM_AUTH_HASH_SECRET to something unique to your system.

CSRF stands for Cross-Site Request Forgery which, under specific
circumstances, can allow an attacker to perform any task your
ZoneMinder user account has permission to perform. To accomplish
this, the attacker must write a very specific web page and get
you to navigate to it, while you are logged into the ZoneMinder
web console at the same time. Enabling ZM_ENABLE_CSRF_MAGIC will
help mitigate these kinds of attackes. Be warned this feature
is experimental and may cause problems, particularly with the API.
If you find a false positive and can document how to reproduce it,
then please report it. This feature defaults to OFF currently due to
its experimental nature.

ZoneMinder now features a new API using which 3rd party
applications can interact with ZoneMinder data. It is
STRONGLY recommended that you enable authentication along
with APIs. Note that the APIs return sensitive data like
Monitor access details which are configured as JSON objects.
Which is why we recommend you enabling authentication, especially
if you are exposing your ZM instance on the Internet.

This option is now the default for new ZoneMinder systems and
should not be changed. Previous versions of ZoneMinder stored
all events for a monitor under one folder. Enabling
USE_DEEP_STORAGE causes ZoneMinder to store events under a
folder structure that follows year/month/day/hour/min/second.
Storing events this way avoids the limitation of storing more
than 32k files in a single folder inherent in some filesystems.
It is important to note that you cannot simply change this
option. You must stop zoneminder, enable USE_DEEP_STORAGE, and
then run "sudo zmupdate.pl --migrate-events". FAILURE TO DO
SO WILL RESULT IN LOSS OF YOUR DATA! Consult the ZoneMinder

When ZoneMinder detects an event it will save the images
associated with that event to files. These files are in the
JPEG format and can be viewed or streamed later. This option
specifies what image quality should be used to save these
files. A higher number means better quality but less
compression so will take up more disk space and take longer to
view over a slow connection. By contrast a low number means
smaller, quicker to view, files but at the price of lower
quality images. This setting applies to all images written
except if the capture image has caused an alarm and the alarm
file quality option is set at a higher value when that is used
instead.

This value is equivalent to the regular jpeg file quality
setting above except that it only applies to images saved while
in an alarm state and then only if this value is set to a
higher quality setting than the ordinary file setting. If set
to a lower value then it is ignored. Thus leaving it at the
default of 0 effectively means to use the regular file quality
setting for all saved images. This is to prevent acccidentally
saving important images at a worse quality setting.

quality but less compression so will take longer to view over a
slow connection. By contrast a low number means quicker to view

When using streamed MPEG based video, either for live monitor
streams or events, ZoneMinder can send the streams in two ways.
If this option is selected then the timestamp for each frame,
taken from it's capture time, is included in the stream. This
means that where the frame rate varies, for instance around an
alarm, the stream will still maintain it's 'real' timing. If
this option is not selected then an approximate frame rate is
calculated and that is used to schedule frames instead. This
option should be selected unless you encounter problems with

description => 'Timestamp images as soon as they are captured',

ZoneMinder can add a timestamp to images in two ways. The
default method, when this option is set, is that each image is
timestamped immediately when captured and so the image held in
memory is marked right away. The second method does not
timestamp the images until they are either saved as part of an
event or accessed over the web. The timestamp used in both
methods will contain the same time as this is preserved along
with the image. The first method ensures that an image is
timestamped regardless of any other circumstances but will
result in all images being timestamped even those never saved
or viewed. The second method necessitates that saved images are
copied before being saved otherwise two timestamps perhaps at
different scales may be applied. This has the (perhaps)
desirable side effect that the timestamp is always applied at
the same resolution so an image that has scaling applied will
still have a legible and correctly scaled timestamp.

There are a few codes one can use to tell ZoneMinder to insert
data into the timestamp of each image. Traditionally, the
percent (%) character has been used to identify these codes since
the current character codes do not conflict with the strftime
codes, which can also be used in the timestamp. While this works
well for Linux, this does not work well for BSD operating systems.
Changing the default character to something else, such as an
exclamation point (!), resolves the issue. Note this only affects
the timestamp codes built into ZoneMinder. It has no effect on
the family of strftime codes one can use.

To detect alarms ZoneMinder needs to blend the captured image
with the stored reference image to update it for comparison
with the next image. The reference blend percentage specified
for the monitor controls how much the new image affects the
reference image. There are two methods that are available for
this. If this option is set then fast calculation which does
not use any multiplication or division is used. This
calculation is extremely fast, however it limits the possible
blend percentages to 50%, 25%, 12.5%, 6.25%, 3.25% and 1.5%.
Any other blend percentage will be rounded to the nearest
possible one. The alternative is to switch this option off
and use standard blending instead, which is slower.

{
name => 'ZM_OPT_ADAPTIVE_SKIP',
default => 'yes',
description => 'Should frame analysis try and be efficient in skipping frames',
help => q`
In previous versions of ZoneMinder the analysis daemon would
attempt to keep up with the capture daemon by processing the
last captured frame on each pass. This would sometimes have the
undesirable side-effect of missing a chunk of the initial
activity that caused the alarm because the pre-alarm frames
would all have to be written to disk and the database before
processing the next frame, leading to some delay between the
first and second event frames. Setting this option enables a
newer adaptive algorithm where the analysis daemon attempts to
process as many captured frames as possible, only skipping
frames when in danger of the capture daemon overwriting yet to
be processed frames. This skip is variable depending on the
size of the ring buffer and the amount of space left in it.
Enabling this option will give you much better coverage of the
beginning of alarms whilst biasing out any skipped frames

ZoneMinder allows monitors to have motion detection to be

relies on the operator resuming motion detection afterwards as
failure to do so can leave a monitor in a permanently suspended
state. This setting allows you to set a maximum time which a
camera may be suspended for before it automatically resumes
motion detection. This time can be extended by subsequent
suspend indications after the first so continuous camera
movement will also occur while the monitor is suspended.

several components then they will all try and write to the same

frame signal loss event is generated, as is another when the
signal returns. This option defines how many points on each

Performance when using Video 4 Linux devices is usually best if
multiple buffers are used allowing the next image to be
captured while the previous one is being processed. If you have
multiple devices on a card sharing one input that requires
switching then this approach can sometimes cause frames from
one source to be mixed up with frames from another. Switching
this option off prevents multi buffering resulting in slower
but more stable image capture. This option is ignored for
non-local cameras or if only one input is present on a capture
chip. This option addresses a similar problem to the
ZM_CAPTURES_PER_FRAME option and you should normally change the
value of only one of the options at a time. If you have
different capture cards that need different values you can
override them in each individual monitor on the source page.

If you are using cameras attached to a video capture card which
forces multiple inputs to share one capture chip, it can
sometimes produce images with interlaced frames reversed
resulting in poor image quality and a distinctive comb edge
appearance. Increasing this setting allows you to force
additional image captures before one is selected as the
captured frame. This allows the capture hardware to 'settle
down' and produce better quality images at the price of lesser
capture rates. This option has no effect on (a) network
cameras, or (b) where multiple inputs do not share a capture
chip. This option addresses a similar problem to the

number of frame writes and a lot of database and disk bandwidth
for very little additional information. Setting this to a
non-zero value will enabled ZoneMinder to group these non-alarm
frames into one 'bulk' frame entry which saves a lot of
bandwidth and space. The only disadvantage of this is that
timing information for individual frames is lost but in
constant frame rate situations this is usually not significant.
This setting is ignored in Modect mode and individual frames
are still written if an alarm occurs in Mocord mode also.

This option allows you to limit the maximum frame rate to

advantage is that encoding video at high frame rates is a
processor intensive task when for the most part a very high
frame rate offers little perceptible improvement over one that
has a more manageable resource requirement. Note, this option
is implemented as a cap beyond which binary reduction takes
place. So if you have a device capturing at 15fps and set this
option to 10fps then the video is not produced at 10fps, but

be the original divided by a power of 2.

corresponds to a 'quality' setting for the video. A low value
will result in a blocky image whereas a high value will produce
a clearer view. Note that this setting does not control the
frame rate of the video however the quality of the video
produced is affected both by this setting and the frame rate
that the video is produced at. A higher frame rate at a

When using streamed video the main control is the bitrate which
determines how much data can be transmitted. However a lower
bitrate at high frame rates results in a lower quality image.
This option allows you to limit the maximum frame rate to
ensure that video quality is maintained. An additional
advantage is that encoding video at high frame rates is a
processor intensive task when for the most part a very high
frame rate offers little perceptible improvement over one that
has a more manageable resource requirement. Note, this option
is implemented as a cap beyond which binary reduction takes
place. So if you have a device capturing at 15fps and set this
option to 10fps then the video is not produced at 10fps, but
rather at 7.5fps (15 divided by 2) as the final frame rate must
be the original divided by a power of 2.

=head1 NAME
ZoneMinder::ConfigData - ZoneMinder Configuration Data module
=head1 SYNOPSIS
use ZoneMinder::ConfigData;
use ZoneMinder::ConfigData qw(:all);
loadConfigFromDB();
saveConfigToDB();
=head1 DESCRIPTION
The ZoneMinder:ConfigData module contains the master definition of the
ZoneMinder configuration options as well as helper methods. This module is
intended for specialist confguration management and would not normally be
used by end users.
The configuration held in this module, which was previously in zmconfig.pl,
includes the name, default value, description, help text, type and category
for each option, as well as a number of additional fields in a small number
of cases.
=head1 METHODS
=over 4
=item loadConfigFromDB ();
Loads existing configuration from the database (if any) and merges it with
the definitions held in this module. This results in the merging of any new
configuration and the removal of any deprecated configuration while
preserving the existing values of every else.
=item saveConfigToDB ();
Saves configuration held in memory to the database. The act of loading and
saving configuration is a convenient way to ensure that the configuration
held in the database corresponds with the most recent definitions and that
all components are using the same set of configuration.
=back
=head2 EXPORT
None by default.
The :data tag will export the various configuration data structures
The :functions tag will export the helper functions.
The :all tag will export all above symbols.
