How to export an event as a video file


Step 1
Step 2
Step 3







Intro
By default ZoneMinder saves events as a sequence of images. It is however
possible to save an event as a video file. Caution is advised when
converting events too video as it is very strenuous on the ZoneMinder
machine, however once you have converted an event it can be
viewed/downloaded any time without additional stress on the server.

First, make sure you have OPT_FFMPEG under Options -> Images set to yes
(checked).
If necessary, set the proper full path for the ffmpeg executable in
PATH_FFMPEG (ex.: /usr/bin/ffmpeg)
Open up the default view for an event and Click the video link located in
the top left corner
Choose a video export file type and click generate.
Download the video to your machine. If video files have already been
generated you will see them listed at the bottom of the page.

When an event gets a video file encoded for it you can choose to
automatically include that event with any future exports. For a more
detailed explanation on how to select and export events investigate How to

1. Prerequisites
To export, download and view the events from ZoneMinder there are 3
prerequisites.

Access to your ZoneMinder website.
An application to unpack the exported files.

For Linux most distributions include an application like unzip or untar.
For Windows an excellent open source alternative to the default archive
manager is 7-Zip




2. Export Methods
There are three ways to export events from ZoneMinder. Depending on what
events you wish to export one of these methods will usually be superior.



2.1 Front end interface method
This is the easiest way to view events if you want to check all events in
the hour/day/week/month or all events for a certain particular camera.

                 


                   
	
              
	

	

		
		2.1.1 Steps
		
 
Login to ZoneMinder as a user who has rights to view the desired monitor.
From the home page you should see a table with columns labeling camera name
events per hour/day/week/month/all. The very bottom column of this table
totals the events across all cameras for the given hour/day etc. Click on
the total events under the hour row to continue.
You should now be on the event view page. This pages purpose is to list the
events selected by your query method. From this view we are provided with
many statistics about individual events. We may choose to review the events
from this page by clicking on the name of the event, however for the purpose
of this how to we will simply choose to export all events by selecting the
check-box in the top right cell. After selecting all the events from this
view we open up the export dialog by clicking the EXPORT button located in
the bottom right corner.
This export options dialog that pops up allows us to select the file type
that is exported. Before clicking the export button you must first make sure
too check the following settings:
	

    
Export Event Details
    
Export Frame Details
    
Export File Format: Zip
	

Once you click the export button ZoneMinder will go through the process of
packaging and formatting the events for you, this process can be quite
intensive for the server if a large number of events are selected. When the
process is completed a download link for a file called zmExport.zip should
pop up, select save file and click ok. It is important to make a note of
where you save your file as you will need to access it later.

2.2 Event Filter

Event Filter
Typical Export form settings
Events Filter form

The filter method of exporting events gives the user the most detail and
control in the event query. As this method allows you to make very refined
queries it does add some complexity to the process. To illustrate the power
of this export method I will show you how Event Filter can create a custom
query that is saved for future use, this custom query will select all events
that have had more than 50 alarm frames on Mondays.
Steps

    On the bottom left side of your ZoneMinder homepage there should be a
button labeled "Filter"
    The form section under the use filter select box is the area where we
will define steps the event filter evaluates. To add the second step for the
event filter simply click the + button on the bottom left of the field-set
        The first filter should be Alarm Frames - greater than - 50
        Your second filter should be and - Weekday - equal to - Monday
    To save this event filter method click on the save button. Make sure to
write in a descriptive name for the filter.

Events Filter save form box

    Executing the event filter after you have saved it is as simple as
clicking execute at the bottom of the page.
    You should now be on the event view page. This pages purpose is too list
the events selected by your query method. From this view we are provided
with many statistics about individual events. We may choose to review the
events from this page by clicking on the name of the event, however for the
purpose of this how to we will simply choose to export all events by
selecting the check-box in the top right cell. After selecting all the
events from this view we open up the export dialog by clicking the EXPORT
button located in the bottom right corner.
    This export options dialog that pops up allows us to select the file
type that is exported. Before clicking the export button you must first make
sure too check the following settings:
        Export Event Details
        Export Frame Details
        Export File Format: Zip
    Once you click the export button ZoneMinder will go through the process
of packaging and formatting the events for you, this process can be quite
intensive for the server if a large number of events are selected. When the
process is completed a download link for a file called zmExport.zip should
pop up, select save file and click ok. It is important to make a note of
where you save your file as you will need to access it later.

Individual camera export
Individual camera view allows you to select specific events
From the individual event view exporting is as simple as clicking export
(top left)

This export Method is the simplest way to check and export an individual
event that has happened recently on a specific monitor
Steps

    From your ZoneMinder homepage open the individual view of a specific
camera
    On the "watch" view of a monitor the recent events should be listed by
date under the live stream. Click on an event from this list to view the
individual event.
    On the individual event view page you should get a stream of the event.
To export this event simply click the Export link located at the top of the
page.
    This export options dialog that pops up allows us to select the file
type that is exported. Before clicking the export button you must first make
sure too check the following settings:
        Export Event Details
        Export Frame Details
        Export File Format: Zip
    Once you click the export button ZoneMinder will go through the process
of packaging and formatting the events for you, this process can be quite
intensive for the server if a large number of events are selected. When the
process is completed a download link for a file called zmExport.zip should
pop up, select save file and click ok. It is important to make a note of
where you save your file as you will need to access it later.

Extracting Events

A note about this section of the how to, For the examples i am using a
custom export_functions.php plug-in that comes native in stagecoach wireless
ZoneMinder installs. Once you have selected your desired set of events you
need a logical way to organize them and store them on your computer. My
suggestion is too unzip all ZoneMinder exports to a specific folder so you
have them all in one place to easily browse and backup.
How to unpack the export files

Most operating systems have many different applications that allow you to
extract zoneminder.zip packages. For this example i will show you one way to
do this.
Linux
Ready to extract the events folder for viewing

    Navigate to the folder where zmexport.zip was downloaded to. In this
example i have 4 zmexport.zip files extracted to the folder
    Double click opening up the archive manager
    Drag the events folder from the archive manager window into another
folder. For ease of use i suggest you make a separate folder to store all
your ZM export events in.

Windows

    Navigate to the folder where zmexport.zip was downloaded to. In this
example i have 4 zmexport.zip files extracted to the folder
    Right-click the filename and select open with your archive manager (e.g
7-zip, winzip or winrar if you are using windows)
    When your archiving software is loaded up you should be able to select
the events folder from zmexport.zip and drag it to your desired location in
the file structure.

Viewing Extracted Events
zmEventImagesMaster.html has a time-stamp identifier so you can extract
multiple events to one folder and still organize them by date

To view the events you have just extracted simply browse to the events
folder. To view the interface of all events open up the newest
zmEventImagesMaster file in Fire Fox. From this page you get a tabbed view
showing you events organized by monitor and chronological order. Within each
events view you can display individual frames from the event or meta data
about the event date/time/length

    Event viewer

    Frames viewer

    Event data view

Events folder structure

    events
        monitor-ids
            event-ID
                zmEventDetail.html (this is the file that contains meta data
about an individual event)
                zmEventFrames.html (this is the file containing a listed
view of all event frames)
                xxx-capture.jpg (individual snapshot from the event)
        zmEventImagesMaster.html (this is the file that acts as the "home"
page for each event extraction. you can extract multiple event sets to the
events folder and acquire a list of these files
