Events and Event Types
Your AXIS 250S MPEG-2 Video Server is capable of performing various actions when
certain types of events occur. The terminology used to describe this is as follows:
• Event type - a defined set of parameters that specify how and when something will
trigger an action.
• Event - one occurrence of an event type.
• Action - what occurs when the event triggers. Examples are the upload of video to an
FTP server, email notification, etc.
• Trigger - the circumstances that start an event. This could be e.g. a pre-programmed
time or a signal from an external device, such as a door switch or a motion sensor.
Configuring Event Types
An event type is a set of parameters describing how and when the server will perform
certain actions. An event type may result in one single event, or it may result in many,
depending on its configuration. The most common kind of event type will trigger the
upload of images to a specified destination. Other actions performed by event types can
include the sending of e-mail, the activation of the output port and various types of event
Setting up a new event type
Click the menu link to Event Types. This opens the list of event types as in the example
below. The list shows various information about the event types currently configured.
Operating the AXIS 250S
AXIS 250S User’s Manual
Click the Add button. This launches the Event Type Setup dialog. Depending on the event
type you require, you will then need to provide some or all of the following information:
• Name - Give the event type a suitable name.
Respond to Trigger...
This setting determines when the event type can be activated. The options are:
• Always - the event type can be activated by the trigger (see below) at any time
• Only during time frame - a trigger will only start the event type during the times
specified. Triggers at other times will be ignored. Select the days and set the period’s start
time and duration. The duration may be set up to a maximum of 168 hours. If a duration of
more than 24 hours is required, then only one weekday may be checked. To use two or
more trigger time frames longer than 24 hours - two or more event types (one for each
period) must be configured.
• Never - the event type is disabled and no actions will be performed.
Trigger Type
The trigger type is what starts the event type. The following options are available:
• Input Ports - This describes the states that the 4 inputs must be in before the event type is
triggered. One or more inputs can be used together, but note that the states for all the
inputs used must first be reached before the event type is triggered.
• Timer - whole time frame - This option will simply use the times specified in Respond to
Trigger... described above.
• Timer - periodically - Use this to trigger the event type at a certain frequency.
Configurable in seconds, minutes or hours. It is also possible to specify the time to
commence triggering. Note that this setting also uses the times specified in Respond to
• Loss of Video - If the video signal disappears, this will trigger the event. A notification of
the event would be a suitable action for this trigger. If the event type has been configured
to upload a video sequence for this trigger, then this will, of necessity, only be the
pre-trigger sequence, if this has been enabled.
• Server Boot - This can be used to trigger the event type whenever the server is started or
restarted. A notification of the event would be a suitable action for this trigger type.
• Log Messages - The server can trigger an event type whenever a system event writes an
entry to a log file. There are three types of log file; Information, Warning or Critical. Select
the level that will trigger the event. Note that the first two alternatives also include
messages of a higher importance, so alternative 1 will trigger the event type the most, as
it also includes Warning and Critical log messages.
AXIS 250S User’s Manual
Operating the AXIS 250S
• Manual Trigger - This is used for manually starting and stopping the event. It is also
possible to use this option to trigger the event via the server’s API.
When Triggered...
These settings describe the actions to take when the event type is triggered. One or more
actions may be selected.
• Upload to FTP server - Select the FTP server to upload images to. Note that FTP servers must
first be configured in Upload Servers. See page 20.
• Upload for - Specify the total time to upload the recording. Configurable in seconds,
minutes or hours. This can be used to continue the upload even after the event has ended.
• Upload as long as trigger is active - This option will terminate the upload as soon as the
event ends.
• Split upload into - Use this to split a long video sequence into several shorter sequences.
Configurable in seconds, minutes or hours. This is recommended if there is likely to be
recordings longer than 30 minutes in duration. The AXIS 250S can easily handle video files
of more than 30 minutes, but they may cause problems for some types of FTP server.
• Include pre-trigger recording - The AXIS 250S is capable of saving video sequences that
originate from the time immediately before the trigger. This can be very useful when
checking to see what happened to cause the trigger. Check the box to enable.
Note that to use pre-trigger recording in event types, pre-trigger recording must first be
enabled in the Video settings.
• Base file name - This name will be used for all of the files saved. If suffixes are also used,
the file name will take the form filename_suffix.
• Add suffix - Add either a date/time suffix, a sequence number (with or without a
maximum value), or select Overwrite. This last option will save one file only and will
constantly overwrite it, whereas using sequential numbering with a maximum will
overwrite the first file as soon as the last file is written.
• Activate output port - This box must be checked to enable the use of the output port. The port
is used to control external equipment.
• Keep active during event - This option allows external equipment to be run/controlled for
the entire duration of the event. This might be necessary to e.g. keep extra lighting on
while saving/uploading a video sequence.
• Keep active for - Specify a fixed length of time the port will be active for.
Operating the AXIS 250S
AXIS 250S User’s Manual
Please keep in mind that the output port can be controlled by more than one event type. This may mean
that the port is the “wrong” state if one or more event types that activate the port are triggered one
after the other. Using more than one event type to control the output is not recommended.
• Send email notification to - Check this box to enable the sending of email to notify recipients
of events. Enter the email address(es) in the field provided. Multiple addresses must be separated by semicolons (;) To add your own text, check the Include text box and enter your text.
Note that a mail server must be configured in the SMTP network settings.
• Send HTTP notification - This method sends a notification to an HTTP server. Select the name
of the server. Note that the destination server must first be configured in Notification Servers.
See the following page.
• Send TCP notification - This method sends a TCP/IP notification. The destination server must
also first be configured in Notification Servers.
Click OK to save the event type setup.
Upload Servers
Clicking this link will open the list of FTP servers currently configured in the server. The
listing shows the name and address of the server, as well as the upload path and user name.
Adding an Upload Server
Click the Add button. This opens the Upload Server Setup dialog. The following
information should then be provided for the new server.
• Name - This can be any descriptive name you like.
• Network address - Enter the IP address or host name of the server. To use a host name, a
DNS server must be specified in the TCP/IP network settings.
• Upload path - Specify the path to the directory where the uploaded images will be stored.
If this directory does not already exist on the ftp server, there will be an error message
when uploading.
• Additional information - In this field you can add extra information about the server. For
example, if the saved video files can also be accessed via a UNC address (e.g.
\\video\file1.mpeg), then you could add text providing this address. This information will
be included in email sent by events that use this server.
• The user name and password you use to log on to the server.
When finished, you can test the setup by clicking the Connect button. The results of the
connection test will then be displayed in a message box.

Notification Servers
To allow your event types to send HTTP and TCP notifications, the necessary servers must
first be configured. The Notification Server list shows the servers currently configured.
These severs are shown as the alternatives when selecting this type of notification in the
event type setup, as described in the preceding section.
Note that event notification server settings have nothing to do with the change of IP
address notification settings.
HTTP Notification
An HTTP notification normally requires some sort of script to be located on the destination
server. This script reads the parameters sent in the notification and then performs some sort
of action.
The following information should be provided for an HTTP notification server:
• Name - This can be any name you like.
• URL - In this field you should provide the IP or host address of the server, the path to your
script, and finally the name of the script. For example:
• Custom Parameters - Enter your own text here. See also below.
• User name/password - If you need to supply a user name and password to access the HTTP
server, provide these here.
• Proxy/Proxy port - If you must pass a proxy server to access the HTTP server, provide the
server’s network address and the port used for access.
• Proxy user name/password - The proxy server may require a user name and password.
• Retry count - If the connection attempt fails, enter the number of times to retry.
• Message - Enter your own text here. This will be displayed in the notification.
This is then what is actually included when the HTTP notification is sent:
For the Custom field the following should be noted:
• The field must be named as a parameter for it to work.
For example: http://servername/...................&CustomParameter=MyTextHere.
• The field must be manually URL-encoded. This means that to use special characters, these must
be coded and not simply typed.
For example, to include a blank space, type %20 instead. The equal sign (=) can be typed
Operating the AXIS 250S
AXIS 250S User’s Manual
The following information should be provided for a TCP notification server:
• Name - This can be any descriptive name you like.
• Network address - Provide the address of the server here. This may be an IP address or a
host name. Note that to use a host name, a DNS server must be configured in the TCP/IP
network settings.
• Port - Enter the port number used for accessing the TCP host.
• Retry count - If the connection attempt fails, enter the number of times to retry.
• Message - Enter your own text here. This will be displayed in the notification.

Audio & Video Settings
The AXIS 250S provides the connection for a single analog camera (or other video source),
on either the BNC connector or the S-Video connector. Ensure that the camera is correctly
connected and powered up before attempting configuration.
• Resolution - the two video resolutions available are CIF and 4CIF. The exact resolution will
depend on the type of camera being used, PAL or NTSC. See also Technical Specifications, on
page 51.
• Color - Select either Color or Black & White. Black & White will provide sharper images at a
lower bandwidth than Color.
• Bit rate - This setting determines how much of the available bandwidth will be used by the
video stream. The bit rate is configurable from 250 to 8000 kBit/s (8 MBit/s). See also Bandwidth, on page 53.
• Input - Select the input the video source is connected to. The following options are available:
• BNC (composite video) - connects a standard video camera or other video source.
• Y/C (S-video) - connects an s-video camera or other video equipment.
• Source modulation - The AXIS 250S supports both of today's common video modulation standards. Select the correct standard from the drop-down list.
• NTSC - delivering 525 lines of resolution at 60 half-frames per second, this is the common
standard in the United States.
• PAL - the dominant standard in Europe, delivering 625 lines at 50 half-frames per second.
• Enable pre-trigger and/or Post-trigger recording - The AXIS 250S MPEG-2 Video Server is
capable of recording directly before and/or after an event occurs. This is achieved by constantly
buffering (and overwriting) a certain amount of the video stream into the internal memory.
When the event is triggered, the memory contents are added to the actual recording.
AXIS 250S User’s Manual
Operating the AXIS 250S
Exactly how much pre-trigger recording will be produced depends mainly on the bit rate
setting. A high-quality video stream will occupy more of the internal memory and thus
shorten the duration of the recording. The length of the pre-trigger recording in seconds
can be roughly calculated by dividing 16 by the bit rate in Mbit/s.
Note that pre-trigger recording must be enabled in the video settings if you wish to use
pre-trigger recording in event types.
The AXIS 250S provides a fully synchronized audio stream at up to CD quality. The
following settings are available:
• Quality - Select the bit rate and sample rate to use. Generally speaking, the higher the setting,
the better the sound quality, but at the higher levels the difference might not be audible. The
default value (128 kbps) provides good quality sound.
• Volume Settings - The Master volume control should not normally need any adjustment. However, if you are using some other audio input device on the Line connector, and the audio level
is not satisfactory, then this level may need to be changed. Configurable between -30 and 30
• Mic input sensitivity - This setting should be set according to the specifications for the connected microphone. If the correct setting is used, there will be no need to adjust the Master
volume level. The volume slider in the web interface will suffice for raising or lowering the volume when viewing the video stream. If you are unsure of the correct setting for your microphone, try both settings.
• Audio Input - Select the input to use for the audio input. The options are:
• Line - connects other audio input devices
• Mic - connects a standard microphone

TCP/IP Network Settings
From the Network Settings, configure the TCP/IP network settings as follows:
Automatic IP Configuration
DHCP - Dynamic Host Configuration Protocol (DHCP) is a protocol that lets network
administrators centrally manage and automate the assignment of IP addresses in an
organization's network. Check the box to allow a DHCP server on the network to assign the
IP address.
DHCP should only be enabled if you are using dynamic IP address notification, or if your version of DHCP
can update a DNS server, which then allows you to access the AXIS 250S by name. If DHCP is enabled
and you cannot access the unit, you may have to reset it to the factory default settings (see page 34)
and then perform the installation again (see page 10).
BOOTP - Check this box to use BOOTP to automatically assign an IP address. Requires a
BOOTP server on your system. BOOTP is enabled by default and is required for installation
using the AXIS IP Installer.
Dynamic IP Address Notification Settings
When the IP address changes by means beyond your control, for example, by DHCP, you
can choose to be notified of the change via HTTP, FTP or SMTP. Click the icon to display,
edit and refine the settings for address notification.
Referring to the table below, configure the dynamic IP address notification settings.
Enabling HTTP means the server will send an HTTP GET request to the specified URL. This can then easily
be taken care of by a designated cgi-script, which registers the request by some means. Custom
parameters can be used by entering them in the field provided. The fields User Name and Password, should
be used if the script is password protected. If you need to pass a proxy server to connect to the URL for the
host, provide your user information in the relevant fields.
Enabling SMTP will send an email notification of any change in IP address. Enter the recipient’s address
and a sender’s address, as well as any text you want to appear in the subject of the email. Note that you
must configure the mail server under Network Settings.
Saves a notification file on an FTP server. Provide the connection details for the server and your user name
and password. If there is a firewall between the server and the FTP server, it is recommended that Passive
Mode is enabled. There are 3 levels of TXT Type to choose from; Short - the IP address only; Extended multi-line file; and HTML - contains the same information as Extended, but includes HTML tags. See also
the On-line help for more information.

Ports & Devices
IO Ports
This page allows you to enable and configure the four inputs and one output supported by
the server. Ports can be enabled or disabled, given descriptive names, and their Normal
state can be configured.
The normal state describes the inactive state for the port. It is also an indication of the
function of the connected equipment and how it is activated. For example, if the activation
circuit in a door switch connected to an input is normally closed, this means that as long as
the door is closed then the state is also closed (inactive). When the door is opened the door
sensor will be active and the input will no longer be in its normal state. This is how events
based on external equipment are triggered.
Thus, in the I/O port list, if the Normal state for an input is set as Open, but the Current
state is shown as Closed, then the port has been activated, and vice versa.
Please note that some external devices may behave incorrectly in the event of an error
condition, e.g. a power cut.

Other IP Setup Methods
Appendix A - Other IP Setup Methods
The AXIS 250S was developed for use with Microsoft Internet Explorer (5.5 or higher) running on Windows XP or 2000. Windows Millennium is not supported, but the video stream may be available.
As an alternative to the ARP command (as described on page 10), you can set the IP address
for your AXIS 250S using any of the following methods - as appropriate for your network
operating system:
Network OS
Refer to...
AXIS IP Installer (requires BOOTP or DHCP to
be enabled in the AXIS 250S’s TCP/IP settings)
Using the AXIS IP Installer, on page 35.
DHCP (disabled by default)
Automatic IP Configuration, on page 30.
BOOTP (enabled by default)
Requiring a BOOTP daemon on your system, this
method operates over the entire network. A
request to an active daemon initiates a search of
the boot table to find an entry matching the
unit’s Ethernet address. The daemon downloads
the IP address to the device if a match is found.
Notes: • Make sure the AXIS 250S is powered up and connected to the network.
• Acquire an unused IP address from your Network Administrator before installing your
AXIS 250S.
• Although no special privileges are required for Windows XP (Home), you will need
Administrator privileges for Windows 2000 and XP (Professional). UNIX systems require
Root privileges.
• Ethernet Address: The AXIS 250S is pre-configured with a unique Ethernet Address
based upon the serial number printed on the underside label of the unit; where the serial
number typically follows the format 00-40-8c-xx-yy-zz. You need this Ethernet address
to complete the installation.

PINGing Your IP Address
By sending a packet to the specified address and waiting for a reply, the PING utility can
determine whether a specific IP address is accessible. It also provides a useful method for
confirming addressing conflicts with your AXIS 250S on the network.
Follow the instructions below in association with Symptoms, Possible Causes and Remedial
Actions, on page 39:
1. Start a Command window and type ping x.x.x.x, where x.x.x.x is the IP address of
the AXIS 250S.
2. If you receive the reply destination host unreachable, then the AXIS 250S is not
accessible on your subnet. You must obtain a new IP address and reinstall the unit.
3. If this does not solve the problem, disconnect the AXIS 250S from the network and run
PING again. See the table below for an interpretation of the results.

Updating the Firmware
Appendix C - Updating the Firmware
The AXIS 250S firmware is stored in Flash memory. This memory is provided by a silicon
chip that, just like any other ROM device, retains data content even after power is removed.
Flash memory is unique because it allows its data to be erased and re-written. This means
you can install firmware updates for your AXIS 250S as they become available - without
having to replace any parts. New firmware can be simply loaded into the AXIS 250S over
the network.
Obtaining Updated firmware
The latest version of the AXIS 250S firmware is available free of charge from the Axis web
site at or from your local distributor.
Updating the firmware
The AXIS 250S Flash memory is updated over the network using FTP. See the detailed
instructions supplied with each new firmware release.
• Always read the upgrade instructions available with each new release, before updating the firmware.
• Upgrading normally takes between 30 seconds and 10 minutes, although it can take longer. After
starting the process, you should always wait at least 20 minutes before power-cycling the AXIS 250S
- even if you suspect the procedure has failed.
• In controlled environments, flash memory updates provide a very safe way of updating the firmware.
However, flash products can become damaged if the update is not performed correctly. Your dealer
reserves the right to charge for any repair attributable to faulty updating by the user.
Customizing The AXIS 250S
AXIS 250S User’s Manual
Appendix D - Customizing The AXIS 250S
Modifying the File System
The Linux-based operating system and flash memory file system make it possible for
advanced users and application developers to customize the AXIS 250S by adding
additional files to the read-write area of the flash memory.
• Modification of the flash file system is NOT supported by Axis. In practice, this means that Axis will
not answer questions relating to custom script or Web page development, but merely wishes to
inform potential application developers of the possibilities afforded by the Linux-based file structure
of the AXIS 250S.
• When attempting to modify the product, you may inadvertently create a problem that will require
you to return the AXIS 250S to its factory default settings. At worst, you may even cause permanent
damage to the unit that renders it unusable. Consequently, Axis strongly recommends that inexperienced users DO NOT modify the file system.
Although modification of the file system is not supported, the Axis web at
does maintain various documents designed to assist third-party development. These include
detailed information such as:
• The Axis Camera API, HTTP-Interface Specification
• Descriptions of useful scripting technologies
Configuration via FTP
As an alternative to configuring the AXIS 250S using a browser, the configuration
parameters of your unit can be modified using the File Transfer Protocol (FTP).
FTP is supported by most operating environments and is a useful method for quickly
downloading standard pre-configurations to one or more servers.
AXIS 250S User’s Manual
Customizing The AXIS 250S
Custom Web Pages
The AXIS 250S contains a re-writable flash memory file system that allows some
directories and files to be changed by the root user, using FTP. This strictly non-supported
product functionality, makes it possible for advanced users and application developers to
add their own Web pages, scripts, and other files to the Axis product.
Customizing Procedures
The existing Administration pages are stored in a compressed read-only area of the file
system. If you intend to try changing them you must adhere strictly to the instructions
provided here and ensure that you DO NOT inadvertently change any files other than those
featured in this section. Failure to comply with this notice may render your product
All files stored in the /etc/httpd/html directory are available through the product Web
server in the virtual directory /local/. The URL to resident pages in the /etc/httpd/html

Editing and Storing Your Web pages
Follow the instructions below to create and save customized pages to the AXIS 250S:
1. Using an html editor, create your html file and store it on your local PC hard drive.
2. Now use ftp to upload the file to the AXIS 250S. Enter the following on the command
ftp <server ip address >
3. Log on as root with the root password pass.
4. Change to the correct directory within the AXIS 250S by entering the following
cd /etc/httpd/html
5. For binary storage of the files (not absolutely necessary, but good practice), type bin.
6. Upload your html files by entering:

Creating a New Home Page
Having created and stored your new custom Web pages in product memory, proceed to
assign one of these pages as your default Home page in the AXIS 250S, as described below:
Adding a new Web page to your AXIS 250S is not something that should be undertaken lightly. Remember: Axis does not support the personalization of product Web pages and strongly recommends that
inexperienced users DO NOT perform such modifications.
1. Start a new ftp session to the AXIS 250S, by entering:
ftp <server ip address >
2. Type bin
3. Navigate your way to the appropriate directory, entering:
cd /etc/httpd/conf/
4. Fetch the boa.conf file, by typing:
get boa.conf
5. Edit boa.conf with a text editor (Notepad is not recommended) and add the following
line to the end of the file:
Alias /index.html /etc/httpd/html/index.html
Alias / /etc/httpd/html
This will create an alias to your own “homemade” index.html file stored in the
/etc/httpd/html/ directory and redirect access to it. Replace the edited boa.conf in
the video server, by using the Put command.
As an alternative to the above, you might like to edit the line starting with Document Root so
that it points directly to the local directory. However, after doing this you will then be unable to
access the original Home pages - so be warned!

Controlling and Monitoring
By entering http requests in your browser’s URL field, you can:
• drive the transistor output high or low
• monitor the status of the 4 digital inputs
This requires you to have root access to the AXIS 250S and consequently, to supply a user
name and password. Login as root and supply the root password (default = pass).
Developers wishing to create applications incorporating sophisticated alarm conditioning using the
transistor output and digital inputs are encouraged to read the Camera API, HTTP-Interface Specification, available from the Axis Web at
Transistor Output
You can use the supported output to directly drive a maximum load of 24V DC at 100mA.
By connecting additional relay circuitry, it can also drive heavier loads.
The transistor output is controlled using http requests, as shown in the following examples:
Example 1: - Set output 1 ON
Example 2: - Set two 300ms pulses with 500ms delay between the pulses on output 1.
Example 3: - Wait 1 second before setting output 1 ON.
Digital Inputs
Four digital inputs allow the AXIS 250S to be configured for device triggered events. For
example, by connecting a motion detector to a digital input, it is a relatively simple
procedure to trigger an event each time the detector is activated.
Querying the Status of Digital Inputs
The status of the four supported digital inputs can be queried in exactly the same way as
the relay output. Simply enter the following URL to query the status of the digital inputs:

(Ba + Bv) x 1000 x 60
= file size in bytes/minute
Bv = Bit rate for video (kbit/s), Ba = Bit rate for audio (kbit/s, 0 if not enabled).
All specifications are subject to change without prior notice.

Appendix G - Bandwidth
As different networks have different characteristics and different amounts of bandwidth
available, the AXIS 250S’s video and audio settings may need to be adjusted to suit the
prevailing conditions.
The Video Bit Rate
The video bit rate describes how much video data is transferred per second, and can be
configured from 0.25 - 8 Mbit/s. Whether or not you should use the available highest rate
depends on the answers to a few questions:
Does your application actually need a video stream at the highest quality? Try viewing the
live video stream and uploading MPEG-2 files using several different bit rates. Using the
lowest acceptable bit rate is recommended.
Are there other bandwidth-dependent services running on the same network? Will the bit
rate used by the AXIS 250S cause problems for these services?
How many clients are likely to be viewing the video stream at any one time? The maximum
number of viewing clients on a 100 Mbit switched local area network is 3.
Image Quality vs Bit Rate
The quality of the video stream in relation to the bit rate can be roughly illustrated by the
graph below.

Other Considerations
• Event types that perform uploads should be kept to the absolute minimum required for your
application. There is a limit of 3 simultaneous uploads at any one time, although more may be
• If installing multiple units on the same network, the bandwidth requirements will be significantly higher.
