Configuration Optimisation
: When set to “Upload Optimised”, the JPEG encoder is
configured to optimize CPU usage for the JPEG image upload. Otherwise, the
configuration of the encoder remains unchanged.
The feature also provides one command:
•
Test / Trigger Upload: Forces an immediate JPEG image upload to the FTP server
using the currently saved configuration. The command then displays the success or
failure of the upload, including the reason if the operation fails.
4.6.1 FTP Server Compatibility
When connecting to the FTP server, the JPEG Image Upload service uses the username and
password provided by the user. If the FTP user account does not require a password, the
password can be left blank in the web interface. If the FTP server allows anonymous access,
both the username and password can be left blank in the web interface.
Because the uploaded files are JPEG images, the FTP transfers are done in binary format rather
than ASCII format.
It is expected that the network where the video encoders are located is a private network,
generally behind a firewall. On the other hand, the FTP server can be either on the same private
network or on an external public network. In order to offer the best flexibility in such situations,
the FTP transfers use „passive FTP‟, where all FTP connections are established from the client
(the video encoder) to the FTP server.
This feature presently does not support transfer over secure FTP.
4.6.2 JPEG Image Names
When uploading a JPEG image to the FTP server, the name of the file created on the FTP
server depends on two factors: the video input number in the encoder as well as the number of
images to keep. The file name pattern is as follows:
videoinput_{videoinputnumber}.{imagenumber}.jpg
