AXIS 200+ and 240 User’s Guide Using the Camera Server

External Web Sites

If your Website is not adversely effected by heavy traffic, and your camera server is connected

directly to an Ethernet network, it is possible to fetch images directly from the camera server.

However, it is recommended that images are accessed over an assisting Web server and not

directly,

when:

• modem connected,

• located behind a firewall,

• subject to high volume traffic,

• used for generating large files, such as

hugesize.jpg

which is very time consuming.

If any of the above circumstances prevail, the best way to transfer images from the camera server to

an assisting Web server, is to use CRON scripts.

Note:

You can use the CRON script facility to collect snapshots periodically.

CRON Scripts

Embedded within your Axis camera server is a time/event based scripting language, CRON. This

service allows you to program event and/or time triggered functions within the camera server.

Any of the following tools can be used for generating a CRON script file:

• The Online Editor. An easy-to-use on-line editor available via the Cron Script - Cron Configu-

ration pages.

• TheText Editor. An integrated text editor available via the Cron Script - Cron Configuration

pages.

• CRON Script Maker. Fully documented CRON applications available in a form-format from

the Network Camera Servers Developers’ pages at http://www.axis.com/ Each form includes a

CRON Script Maker containing several interactive fields for generating custom CRON scripts.

• Any common text editor. Edit using any common text editor and download the file using FTP.

Script Format

A CRON script can include one or several entries. Each entry includes the following elements:

• Comment(s)

• A trigger condition

• Command(s)

• An entry termination character

Note:

Only one CRON script can be resident within the camera server at a time.
