FTP
Video Server not only has web service for easy access but also has a built-in FTP service to
make system integrators easy to use. According to settings on the application page, Video
Server can sequentially send updated snapshots over a specific period to an external server
with choices of overwriting and time suffix. For security staff, Video Server can directly send
snapshots to an external server as evidence according to event settings. Through Video
Server’s FTP daemon, administrators can quickly update configurations and maintenance.
Those files with GIF extensions which are used for a homepage layout and can be read and
overwritten. They also can be downloaded by managed users. Other files will be explained
below.
Uploading snapshots periodically to an external FTP server
In sequential mode, Video Server will send out snapshots according to interval and period
settings. If snapshot files are intended for quick updates, it is better to skip date and time suffix.
The file name will then be video.jpg. If the snapshots are used for occasional monitoring, suffix
with date and time can help administrators classify them easily.
Customizing homepage images
There is a small icon before each link that can be changed by administrators. Administrators
may change the look of the logo, background and image buttons by him or her self. There are
three types of logos and backgrounds, blank, default and other URL. The default method will
use the image stored in the Flash memory. Administrators may change the default logo,
background image and button images by uploading customized ones. The followings are the
referenced file names and size limitations.
Object File name Maximal size
Logo logo.gif Logo and background share 8000 bytes
Background back.gif Logo and background share 8000 bytes
Link icon btn_text.gif 2000 bytes
Viewing system log
Download SYSTEM.LOG and open it with any text viewer. The content of the file reveals useful
information about configuration and connections after the system boots up. It helps
administrators to easily find out who and how Video Server was accessed since all network
access to Video Server is recorded with timestamp. The system log will scroll to keep the
newest messages as eliminate old ones.
