AXIS 2400/2401 Admin Manual Troubleshooting 43
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.
Your AXIS 2400/2401 works
locally, but not externally. Firewall protection. Check the Internet firewall with your system administrator.
Default routers required. Check if you need to configure the default router settings.
The Internet site is too
heavily loaded. Use a script running on your web server to relay images from the
AXIS 2400/2401 to the Internet.
Triggering difficulties with
programming scripts. Unable to trigger on both
positive and negative
transitions of the Control
Button and/or I/O ports
(double-edged triggering). 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:
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.
Bad snapshot images. Display incorrectly
configured on your
workstation. 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.
Incorrect exposure in images. Incorrect line termination. 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).
