AXIS 2400/2401 Admin Manual
Symptoms
Your AXIS 2400/2401 works
locally, but not externally.
Triggering difficulties with
programming scripts.
Bad snapshot images.
Incorrect exposure in images. Incorrect line termination.
Note:
If you still have a problem after reading this information, please contact your reseller or check
the FAQ on the Axis Website at www.axis.com.
Possible causes
Firewall protection.
Default routers required.
The Internet site is too
heavily loaded.
Unable to trigger on both
positive and negative
transitions of the Control
Button and/or I/O ports
(double-edged triggering).
Display incorrectly
configured on your
workstation.
Remedial actions
Check the Internet firewall with your system administrator.
Check if you need to configure the default router settings.
Use a script running on your web server to relay images from the
AXIS 2400/2401 to the Internet.
Repetitive trigger conditions that occur in quick succession can be
missed. This is because the command initiated by the first trigger
event may not have been fully executed before the second event
starts. This scenario is demonstrated in the illustration below:

Trigger
This feature has particular significance when using commands that
take a relatively long time to process, e.g. mail or ftp, especially if
they are transmitting a pre/post alarm buffer.
In Display Properties, configure your display to show at least 65000
colors, i.e. at least 16-bit.
Using only 16 or 256 colors on your display will produce dithering
artifacts in the image.
If the AXIS 2400/2401 is to be connected in parallel with other
equipment, disable the input termination by turning the
corresponding DIP switch to the up-position (OFF). Inversely, when
not using other equipment, set the Termination dip-switch to ON
(default setting).
