View source for Upload images to a remote FTP server

<font size='2'>
==Description==
The camera can be set up to upload images on a remote ftp server periodically.

==Additional features==
* Launch a php script on the server - for example, to resize or move the images.
* Download and update the camera parameters from a configuration file stored on the server.

==Quick Instructions==
* Server: create an ftp user/password pair for the camera.
* Camera: edit /etc/conf.d/ccamftp.conf
* Camera: enable ftp uploading
 1. 192.168.0.9 -> Parameter Editor -> check the '''camftp'''-group -> View/Edit link -> set DAEMON_EN_CCAMFTP to 1
 2. 192.168.0.9 -> Parameter Editor -> scroll down to the second table and save the configuration.

==Camera: /etc/ccamftp.conf==
* Able to launch a specified php script on the server - to resize images, for example.
* Listing:
 ; Configuration file for the "webcam" mode fro the automatic upload of the images to the remote ftp server over the ftp.
 ;Enable the script by specifying a non-zero value in the next line
 ENABLE=0
 ; This file should be placed to the /etc/conf.d/ccamftp.conf
 ; The the camera will automatically start ftp upload as soon as it is powered up if/etc/conf.d/ccamftp.conf exists and is not disabled
 ; To disable the script from running - remove or rename this file in the camera
 ;
 ;here are parameters written in the camera itself - will use if no remote configuration is available
 ;remore server parameters
 ;file name .jpeg will be added for the images to upload (i.e. sample_camera.jpeg), .conf - for the remote configuration file (i.e. sample_camera.conf)
 INAME=sample_camera
 ;ftp server ip (should be numerical)
 SERVER=127.0.0.1
 ;user name and password for ftp access to the remote server
 USER=some_user
 PASSWORD=some_password
 ;directory path on the remote server to uplooad the files
 REMOTE_DIR=some_image_directory
 ;directory on the remote server where camera will try to look for the configuration data 
 REMOTE_CONF_DIR=some_conf_directory
 REMOTE_SCRIPT_PATH=http://some_server_ip/some_directory/some_script.php #should be IP, not host name
 ; you may create the file on the remote server with the same lines as the following, they will be used instead of this configuration file when the camear will contact the server.
 
 ;upload repetition period in seconds (300= one frame each 5 minutes
 PERIOD=120
 
 ;specify how long the script should wait for data upload/download operations before giving up current attempt (it will try again and again next periods)
 TIMEOUT=60
 
==Update the camera's configuration from the server==
* If there's no need for updating the configuration the file does not have to exist.
* The file name must be exactly as the INAME parameter value in /etc/conf.d/ccamftp.conf plus the '''.conf''' extenstion, example:
 INAME=sample_camera => sample_camera.conf
* In the end of the configuration file there must be "FINISH=1" - this is done to make sure the whole configuration file is downloaded to the camera.
* All the parameters names can be found at 192.168.0.9->"Parameter Editor" or on the camera in /etc/autocampars.xml

* sample_camera.conf example listing:
 ;External FTP server configuration file - downloaded and used by the camera for updating parameters
 ;All the parameters names can be found at 192.168.0.9->"Parameter Editor" or in /etc/autocampars.xml
