1 Why PHP?
PHP, which stands for "PHP: Hypertext Preprocessor" was chosen as the scripting language to use in some Axis Video products since:
! PHP is a well-known and widely used scripting language; in Feb 2001 an
estimate of 23% of all Internet web servers used PHP (nearest "competing" script language was Perl with about 7%).
! The language syntax closely resembles Java, Perl and C, making it easy to learn
for anyone with basic programming skills.
! Version 3, PHP3 could easily be scaled down to a smaller footprint required for
embedded devices.
! PHP enables the creation of dynamic web pages quickly; the PHP code is simply
embedded into the HTML code. At the most basic level PHP can do anything that any other scripting language or CGI program can do, such as collect html form data and generate dynamic page content.
! PHP is a complete scripting language with functionality such as file operations,
network sockets, e-mail client (SMTP) and an FTP client. All very useful in Network Camera applications.
The integration of event handling in Axis Video products, and a powerful scripting language such as PHP, gives knowledgeable developers endless opportunities to tailor the functionality of Axis Video products to fit their specific needs.

Revision 0.91 June 2001 3
PHP3 Guide
1.1 What is PHP
PHP (officially "PHP: Hypertext Preprocessor") is a server-side HTML-embedded scripting language.
Simple answer, but what does that mean? An example:
Example 1-1. An introductory example
1 2 <html> 3 <head> 4 <title>Example</title> 5 </head> 6 <body> 7 <?PHP echo "Hi, I'm a PHP script!"; ?> 8 </body> 9 </html> 10
Notice how this is different from a CGI script written in other languages like Perl or C
-- instead of writing a program with lots of commands to output HTML, you write an HTML script with some embedded code to do something (in this case, output some text). The PHP code is enclosed in special start and end tags that allow you to jump into and out of PHP mode.
What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server. If you were to have a script similar to the above on your server, the client would receive the results of running that script, with no way of determining what the underlying code may be. You can even configure your web server to process all your HTML files with PHP, and then there's really no way that users can tell what you have up your sleeve.
A lot of information about PHP can be found on the Internet:
http://www.PHP.net

2 PHP3 and the Video Server
Axis has removed some functions from the standard PHP3, and created some additional functions to suit our products. The name of Axis´ modified version of PHP3 is called PHP3-Lite. The functions among others, that are removed are those that handle:
! Database functions ! PDF functions ! Mathematic functions
Axis recommends checking that PHP3-Lite supports the functions required before creating custom scripts. This can be checked by looking in the PHP3-Lite manual on our Web site: http://www.axis.com
There are some applications that are shipped with the Axis 2400/2401 products; besides these applications the additional PHP3-scripts that define extra functions are explained in Appendix A at the end of this document.

Please keep in mind that the manufacturer of the flash chips estimates the number of writes to the flash chips to about 100,000. Writing a lot of temporary files to flash must thus be avoided. Use the ram disk mounted on /tmp instead.
3.1 Limitations
For the moment it is not possible to activate more than one script at a time. So if many scripts need to be running at the same time, then delay upgrading the Video Server with Linux!
Note: It´s not possible to downgrade to OSYS again, after having upgraded to Linux

3.3 Scripts
Tip: A very useful program to fetch or upload a script to the product, is Ultra Edit;
This can be downloaded from the following Web site:
http://www.ultraedit.com/
Tip: To log all possible errors, include the row
error_reporting(E_ALL);
in the script.
Turn off this option with the row:
error_reporting(0);
3.3.1 Complete script examples
It´s possible to create scripts and put them inside the video server. In Appendix C of this document are complete PHP3 scripts that can be used, which are customized for the most common applications. To run these scripts a task.list file for each script is attached (read more about task.list in section 3.3.3). Scripts for the following applications are available:
! A script that will upload specified images buffers via FTP and the Ethernet
interface.
! A script that will upload specified image buffers via FTP and the Ethernet
interface, and also send a mail as specified
! A script that will upload specified sequential images via FTP and the Ethernet
interface. The uploaded images will be named according to the parameter $suffix.
! A script that will upload specified sequential images via FTP and the Ethernet
interface. The uploaded images will be ordered in a structure defined by their date.
! A script that will upload specified image buffers via SMTP and the Ethernet
interface.
! A script that will upload specified sequential images via FTP and the Ethernet
interface. The uploaded images will be ordered in a structure defined by their date. Upon alarm event (indicated by an existing file named according to $alarm_file) images from the alarm buffers will be uploaded and a mail will be sent as specified by the appropriate parameters.
How to upload a script to the video server and to run it is shown in section 3.3.4 and
3.3.5.

3.3.2 Script generated by the Application Wizard
The wizard in the video server can generate the most basic scripts, and these can then be extended and modified to fit a particular applications needs though Axis recommends creating the scripts from scratch and putting them inside the video server. How to accomplish the above, follow the instructions on the next page.

PHP3 Guide
3.3.2.1 Get the script that the wizard in the Video Server has created
Start by going through the wizards in the Video Server, then open an FTP session to the Video Server. Follow the instructions below to see how this can be accomplished:
Open a DOS session and type the following commands:
1. Go to the path where the script is saved
Eg: c:\axis\php
2. ftp <ip-address to the camera>
Eg: ftp 10.13.9.73
3. Type the user name
Eg: user name: root
4. Type the password
Eg: password: pass
5. Type: bin
6. Type: hash
7. Type: cd etc At startup, utask reads the file /etc/task.list and parses it for event entries. Therefore, it must be fetched to be able to run the script in an automatic fashion. (See also section 3.3.3 The task-Scheduler.)
8. Type: get task.list
9. Type: cd php
10. Type ls to see the file names for the files that the wizard has created:
Ex: ls
11. Type: get <the script that is to be changed>

Note: After having created a script with the application wizard, push the remove button or restart the unit before creating a new one! (This doesn't work if it's a script that has been created from scratch, then the script has to be killed by using telnet).
After following the steps on the previous page, it is possible to look at the script that the wizard in the Video Server has created (use for example Notepad to open the script).

$startcount="";
shoot(2,30000);
Only used if suffix = "sequence"|"sequence_max" Set parameters for the image-format. Compose the command to run for image­taking.
3.3.3 The task-scheduler
The task-scheduler is used to start programs or scripts when certain events occur. The scripts can be shell-scripts or PHP3-scripts, and can start the buffering of images or upload files by using FTP or SMTP.
The task.list is the configuration file for utask which is a task-scheduler similar to cron or at. The task.list features event-detection, based on date and time, a simple socket for external events, and the ability to start any task and process management to avoid runaway childs processes.
At start-up, utask reads the file /etc/task.list and parses it for event entries. If the file /etc/task.list does not exist when utask is started, then utask goes into a stand-by mode. When /etc/task.list has been created, or modified, a SIGUSR1 need to be sent

PHP3 Guide
to utask in order for it to reread /etc/task.list. This can be done by issuing the system (Telnet) command 'kill -10 <utask-pid>'.
3.3.3.1 Syntax
An entry in /etc/task.list has the following syntax :
<event>%<program>:<args>;
<event> = is the event description <program> = is the program to start
<args> = are the arguments to be passed to <program>.
<event>
The maximum number of events is 64. An event description should contain one or more of the following definitions.
Definition Meaning
[hh:mm-hh:mm] - Time period time( h(...) m(...) s(...) ) - Time(hours,minutes,seconds) [dd/mm-dd/mm] - Date period date( w(...) m(...) d(...) ) - Date(day,month,date) pattern( (...) (...) ... ) - External events once - Start only once immune - Never interrupted
Time and Date values are given as a list of values (separated by a comma) and/or intervals (separated by a minus sign):
Hour = 0-23 Minute = 0-59 Seconds = 0-59 Day of the week = 0-6 ('0' means Sunday) Month = 1-12 Date = 1-31.
Patterns are defined as strings and follow the specific format <Client>:<Data>;
<Client>
Is the client application sending <Data> to utask. The Data has to be atomic i.e. if the client wants to notify two events at the same time, it has to write

Revision 0.91 June 2001 13
PHP3 Guide
<Client>:<Data1>;<Client>:<Data2>;.
These patterns are read from /tmp/utasksocket. By default, if an event is trigged, the program runs, exits and starts again as long as the triggering event is valid.
utask start at most five (5) child-processes. When the maximum number of child processes has been exceeded, utask has to decide how to proceed. utask usually kills the process with the lowest priority (if the pending task has a higher priority than this process). The entries in the configuration file (task.list) are ordered by growing priority, i.e. later entries precede earlier entries.
'once'
Specifying 'once' tells utask to skip starting the program as long as the event has not been invalidated. utask checks for events ten times every second (if not in stand-by mode). Thus, if an event is specified to run at a certain point in time, say 'time(h(0) m(0) s(0) )', then this would run the program up to ten times since the event is active during a whole second.
'immune'
utask also provides the user with the possibility of protecting child processes to be prematurely killed by using the 'immune' tag in the script entry. An 'immune' script will always run until it terminates.
3.3.3.2 Examples
Here is an example of a task.list.
The first two entries uses PHP3 to execute scripts mentioned later in this document.
# FTP transfer once every 15 minutes uninterrupted. time(m(0,15,30,45)) immune once % /bin/php : ./ftp.php;
# Mail the current syslog once every day. time( h(0) m(0) s(0) ) once % /bin/php : ./mail_syslog.php;
# Sends and alert message every time I1 and I2 are high at the same time... pattern((IO1:H)(IO2:H)) once % alert : "Input 1 and 2 detected";
3.3.4 Put a new or changed script inside the Video Server:
If a new script is created or something has been modified in the script that the wizard has created, then the new file must be uploaded into the Video Server. To do this follow the instructions below:
Note: When writing the scripts use for example Notepad.

Upload a PHP3 file into the Video Server
1. Open a DOS session and open an FTP session from the path where the PHP3 file resides. Eg: c:\axis\PHP
2. Check that the file exists by typing dir Eg: c:\axis\PHP dir
3. If the file is to be executed as a link, then the file has to have the extension PHP3. If the file doesn't have this then rename the file with the DOS command ren. Eg: c:\axis\PHP ren script.doc (the old filename) script.php3 (the new filename)
4. If the file exists and has the correct filename, then open an FTP session to the Video Server: Eg: c:\axis\PHP ftp <the Video Server ip-address>
5. Then type the user name: Eg: c:\axis\PHP user name: root
6. Then type the password: Eg: c:\axis\PHP password: pass
7. Type: Eg: c:\axis\PHP cd etc/httpd/html

3.3.5.2 Telnet
For development it might be useful to connect to the Network Camera by Telnet. Depending on what product is used, this is either enabled by default and have authentication or can be enabled by editing the /etc/inittab. If the product require editing of the /etc/inittab, there will be no authentication for the Telnet connection and no password will be required for access.
Important: Enable this option for experimental use only. Never leave the Telnet access enabled when having the Network Camera installed on a public site.
3.3.5.2.1 To enable Telnet support
Open an FTP session towards the Network Camera and type the commands viewed in bold below:
C:\Axis >ftp <ip address of camera> Connected to <ip address of camera> 220 Axis 2100 Network Camera 2.12 Feb 05 2001 ready. User (<ip address of camera>:(none)): root 331 User name okay, need password.

5 Appendix A – Included application
Note: The general rule is to not use a function when it’s usage
is not fully understood!
5.1 Introduction
This document explains some of the applications that are shipped with the Axis 2400/2401 products.
These applications are:
! sh, the shell used on the cameras (a modified sash) ! bufferd, a program for buffering images ! utask, a program for scheduling tasks (similar to cron or at).
Besides these applications the additional PHP3-scripts that define extra functions are explained.
The task-scheduler is used to start programs or scripts when certain events occur. The scripts can be shell-scripts or PHP3-scripts, and can start the buffering of images or upload files by using FTP or SMTP.
5.2 The shell - sh
sh is a rewrite of David Bell's sash.
The commands available in sh are essentially the same as the ones commonly used in other shells on any Linux/Un*x system, so the manual pages can often be of use. The difference is that the commands in sh have been simplified, i.e. options have been removed. Besides these modifications some commands have been added which are not part of the original, and thus not documented as a manual-page.

Appendix A – Included Application
5.2.1 Built in commands
The shell includes a help command, which lists the available functions built in the shell (see also Appendix B).
5.3 The image-buffer - bufferd
The application bufferd captures images and stores them on the ram-disk in a FIFO-order, that is, the newest captured image overwrites the oldest.
By default initd starts a bufferd as a daemon. This daemon is listening for messages on the socket /tmp/bufferdsocket. As a consequence it would not be recommended to start several daemons as this would result in one daemon overwriting what the other daemons writes.
The preferred way of using bufferd is depicted in the example below. What happens when a call to bufferd is made is that the started process writes messages to the socket /tmp/bufferdsocket and then dies. Depending on which options are used when starting a buffer, bufferd starts one or two processes for handling image capturing. These processes capture a number of images according to the argument given.
5.3.1 Options
The valid parameters for bufferd are:
Option Meaning
-start Start a buffer.
-reset Remove a buffer.
-stop Stop a buffer. Start as a daemon.
-d
-buffername
<buffername>
-uri <request-
string>
This option should only be used when starting at start-up from initd or when the first instance is to be started.
The name of the buffer on which the options -start, -stop and ­reset should act. bufferd will create a directory in /tmp named <buffername> in which the images will be stored.
The request-uri. Specification of the image-format as described in the HTTP-API
specification (pdf-document). The protocol should be 'FTP'
instead of 'http'. The document can be found on our web site

-postdelay
<delay>
-predelay
<delay>
-pre <number>
-post <number>
-format <format-
string>
Delay between images in milliseconds.
Same as -postdelay but sets an additional variable.
Number of pre-alarm pictures, i.e. number of images to save before stopping the buffer.
Number of post-alarm pictures, i.e. the number of images to save after stopping the buffer.
Naming convention of the files.
-snapshot Take one picture.
-immediate Take one picture and stop the buffer.
5.3.1.1 By Default
If the option '-buffername' is omitted, the buffer used defaults to 'buffer' ('/tmp/buffer') The protocol-specification in the request-uri should be 'FTP', instead of 'http', as this does not generate http-specific headers.
The default delays (postdelay and predelay) are one(1) second (1000 milliseconds).
The default number of images before and after an alarm (pre and post) is 10.
The format-option specifies how the files are named.
Character-expansion is supported with %y (year), %m (month), %d (date), %H (hour), %M (minute) and %S (second) corresponding to the date and time the file was created.
Also supported is %i, which specifies the file-number, and can be followed by a number specifying how many digits are allowed.
The default format is 'snapshot_%y%m%d_%H%M%S_%i4'.

Appendix A – Included Application
5.3.2 Examples
This example shows how to take one(1) image with camera one(1). The resulting image will be of size 640x480 and with other attributes set according to what the camera is set to. The image will be stored in /tmp/SNAP/ and named snapshot.
bufferd -start -buffername SNAP -snapshot -pre 1 -format snapshot -uri ftp://axis­cgi/jpg/1/fullsize.jpg
The following example can be used in a PHP3-script, and is equivalent to the example above.
function shoot() { $command = "bufferd -start -buffername SNAP"; $command .= " -snapshot -pre 1"; $command .= " -format snapshot"; $command .= " -uri ftp://axis­cgi/jpg/1/fullsize.jpg"; system($command); }
The following example creates a buffer that saves its images to the directory /tmp/ALARM/, where the files are named after the creation-time. The captured images will be half-sized (320x240) and captured every two(2) seconds by the first camera. Five(5) images before and two(2) images after the buffer is stopped, are saved.
bufferd -start -buffername ALARM -uri ftp://axis-cgi/jpg/1/halfsize.jpg -pre 5 -post 2 -postdelay 2000
This example shows how to stop the buffer started above.
bufferd -stop -buffername ALARM
This example resets (i.e. stops buffering and clears the directory) the buffer specified in the last example.
bufferd -reset -buffername ALARM
Let's say a method of buffering images is required, and when an arbitrary event occurs, read alarm; the images taken will be handled and the buffering should thereafter continue. The following example illustrates the steps to take (using the examples above):

Revision 0.91 June 2001 24
Appendix A – Included Application
bufferd -start -buffername ALARM -uri ftp://axis-cgi/jpg/1/halfsize.jpg -pre 5 -post 2 -postdelay 2000
(This starts the buffer and can be specified in a start-up script or as an event for utask) When an event occurs, as specified for utask (see below) the following command sequence is used to handle the buffer:
bufferd -stop ALARM
{ handle images}
bufferd -reset ALARM bufferd -start -buffername ALARM -uri ftp://axis-cgi/jpg/1/halfsize.jpg -pre 5 -post 2 -postdelay 2000
The handling of the images can for instance be done with the PHP3-function 'ftp()' below (see also /usr/php/template_upload_cont.php3 on the device).
5.4 The PHP-libs
Included in the distributed firmware are a few PHP3-scripts that define functions, which are intended to help developers use the camera's functionality. These scripts are located in the directory /usr/php. Currently the included files are:
/usr/php/alert.lib /usr/php/ftp.lib /usr/php/log.lib /usr/php/mail.lib /usr/php/ppp.lib
In order to use these functions the files need to be included in the script using them. The arguments used in the function-calls are also required to be defined/declared in the calling script.
5.4.1 alert.lib
This script implements a function that connects to a host and leaves a message. This function requires an application be running on the contacted host that can handle the alert.
Axis Communications AB does not provide support for application development of any kind. The information here is provided "as is", and there is no guarantee that any of the examples shown will work in your particular application.
Revision 0.91 June 2001 25
Appendix A – Included Application
function alert($host,$protocol,$port,$message) { ... }
$host (not null) The host-name or address to send the alert to. $protocol Specify the protocol (0 = TCP, 1 = UDP). Default is '0' $port The port to connect to. Default is '15' $message the message to be sent (ASCII)
The timeout for a connection-attempt is 60 seconds. On error the function returns '1' (connection failed), '2' (a parameter was missing) or '$SOCK_CONNECT_FAILED'. If the connection failed this is logged in the syslog.
5.4.2 ftp.lib
This function has encapsulated the built-in PHP3-functions for FTP.
function ftp($host,$user,$pass,$time,$delay,$source,$des tination,$suffix,$countermax,$startcount,$port, $passive_mode) { ... }
$host (not null) FTP Host-name $user (not null) User-name $password (not null) Password
$time $delay delay between transfers in milliseconds.
transfer period in seconds (time < 0 is infinite (i.e. never leave this function), time >= 0 is once).
(not null) Source specification. If the source file is a directory then the command tries to
$source
$destination (not null) Destination specification. $suffix

transfer each file in this directory. When transferring a whole directory, time and delay are ignored.
Defines the type of stamp to be added to the filename. Valid o
tions are: "default", "date", "sequence",
Appendix A – Included Application
"sequence_max".
$countermax
$startcount $port Port on the FTP-server to connect to.
$passive_mode
On error, the function returns '1' (connection failed), '2' (login failed), '3' (upload failed), '4' (parameter error) or '5' (could not set passive mode). Parameter error occurs when any of $host, $user, $pass, $source or $destination is unspecified, or the parameter $suffix has an invalid value.
Defines the suffix maximum index. Only applies when $suffix = "sequence".
Defines start value for the suffix index. Only applies when $suffix = ("sequence"|"sequence_max").
Choose passive mode. "on" or "off". In passive mode, data connections are initiated by the client, rather than by the server.
5.4.3 log.lib
This function allows a PHP3-script to append an entry to the system log.
function log($message) { ... }
$message Message to be appended to the system log
The function makes a call to the PHP3-function 'error_log($message,0)'.
5.4.4 mail.lib
This function issues a system call to smtpclient.
function mail($subject,$from,$reply,$to,$copy,$file,$att ach) { ... }

Revision 0.91 June 2001 27
Appendix A – Included Application
$subject Message subject (default is 'no subject') $from (not null) Message's author $reply Reply should be sent to this user (default is $from) $to (not null) Recipients $copy Copy the message to other recipients $file Message read from file $attach File to attach
The script requires that a valid mail-server has been entered in the settings for the camera.
Although the argument '$file' can be unspecified, this is NOT recommended as this sets smtpclient in interactive mode and thus locks the execution of PHP.
On error, the function returns '1' (no sender specified) or '2' (no recipient specified) otherwise the function returns '0'.
5.4.5 ppp.lib
These functions allow a PHP3-script to control the use of ppp-connections through the ppp-wrapper.
function ppp_getpid() { ... }
Called from ppp_start() and ppp_stop(). Returns current pppwrapper pid as reported by the file '/var/log/pppwrapper.pid'.
function ppp_getstat( $num_of_checks ) { ... }
Called from ppp_online(). Returns current ppp status by reading the pppstat.log.

Revision 0.91 June 2001 28
Appendix A – Included Application
Returns '1' if it reads "ON", otherwise returns '0'. $num_of_checks is the number of attempts to read the file '/tmp/pppstat.log'.
function ppp_start() { ... }
Called from ppp_online(). Sends SIGUSR1 (10) to the currently running ppp-wrapper. If the wrapper isn't running the function returns '-1' and an error is logged in the syslog.
function ppp_stop() { ... }
Called from ppp_offline(). Sends SIGUSR2 (12) to the currently running ppp-wrapper. If the wrapper isn't running the function returns '-1'and an error is logged in the syslog.
function ppp_online($behavior, $max_attempt, $ppp_interval) { ... }
Initialize ppp connection. Returns '1' if connection is established, '-1' on error and logs the error in the syslog. $behavior describes the type of behavior of the ppp connection (used when closing the connection) and be either "CloseAfter" or "Optimized". $max_attempt is the number of attempts to connect before failing. $ppp_interval is the delay in seconds between connection attempts.

function ppp_offline($behavior, $sec) { ... }
Close ppp connection $behavior describes the type of behavior of the ppp connection and can be either "CloseAfter" or "Optimized". $sec is the time in seconds to wait before calling ppp_stop() if $behaviour="CloseAfter". If $behaviour="Optimized" no waiting is done, ppp_stop is called immediatly.
5.4.6 Examples of usage
The first example depicts how to use the FTP-function in combination with the bufferd-example:
<?php
include "/usr/php/ftp.lib"; include "/usr/php/log.lib";
$host="host.domain"; $user="user"; $pass="password"; $time="0"; $delay="0"; $source="/tmp/SNAP/snapshot.jpg"; $destination="snapshot.jpg"; $suffix="date"; $countermax=""; $startcount=""; $port="21"; $passive_mode="on";
shoot();
$res = ftp($host, $user, $pass, $time, $delay, $source, $destination, $suffix, $countermax, $startcount, $port, $passive_mode);
if($res == 1) {
log("upload script - Could not connect the host");
} else if($res == 2) {
log("upload script - Could not login on host");
} else if($res == 3) {

} else if($res == 4) {
log("upload script - something wrong with parameters");
} else if($res == 5) {
log("upload script - could not turn passive mode on/off"); }
?>
The second example depicts how to use the mail-function, and is the script mentioned as mail_syslog.php in the utask-example:
<?php
include "/usr/php/mail.lib"; include "/usr/php/log.lib";
$subject="Todays messages"; $from="root@camera.domain"; $reply=""; $to="cam-admin@host.domain"; $copy=""; $body="/var/log/messages"; $attach=""; $res = mail($subject, $from, $reply, $to, $copy, $body, $attach); if($res == 1) {
log("mail script - Could not send mail:no sender\n");
} else if($res == 2) {
log("mail script - Could not send mail:no recipient\n");
}

7 Appendix C - PHP3 Script Examples
On the following pages complete PHP3 scripts can be found, which are customized for the most common applications. To run these scripts a task.list file for each script is attached. This is needed because utask reads the file /etc/task.list at startup, and parses it for event entries. Therefore, it must be fetched to be able to run the script in an automatic fashion. (See also section 3.3.3 The task-Scheduler.) The script and task.list files can be downloaded from Axis web site (www.axis.com)
