4.2.2 Example 2 – FTP Upload of Images
This script will upload 2 pre-alarm and 2 post-alarm images via FTP. It is fairly general and may
be used in many different configurations.
4.2.2.1 The task.list
once immune % /bin/bufferd : -start -buffername CAM1 -pre 2 -post 2 -predelay
1000 -postdelay 1000 -uri ftp://jpg/1/352x288.jpg;
date(w(0,1,2,3,4,5,6)) pattern((IO0:/)) immune once % /bin/sh : -c php
/etc/httpd/html/alarm_ftp_net.php3;
The first entry in the task.list will start a buffer (CAM1) that continuously fetches 2 pre-alarm
images from camera 1 and is prepared to fetch 2 post-alarm images. The images are fetched at
rate of 1 frame per second (1000ms).
The second entry specifies that when input one goes high (rising flank), then the script
alarm_ftp_net.php3 will be executed.
4.2.2.2 The Script
The first section of the script contains the available parameters, which may be changed according
to requirements.
<?
$buffer_prefix = "CAM"; // The prefix of the name
//of the buffer(s) started
$sources = "1"; // The index of the name(s)
//of the buffer(s) started
$image_format = "fullsize"; // The format of the images
//specified to be taken
//according to the HTTP-API
$pre = 2; // Number of pre alarm
//images to be taken
$post = 2; // Number of post alarm
//images to be taken
$predelay = 1000; // Delay between pre images
//in milliseconds
$postdelay = 1000; // Delay between post
//images in milliseconds
$ftp_server = "10.13.9.130"; // The server to upload to
$port = "21"; // The port to connect to

//("yes") or off ("no").
//(See documentation on FTP
//protocol)
$destination = "upload/2400test"; // The path to append to
//all uploads. This path
//must exist on the
//server prior to upload.
