Slow video
Outdated drivers for graphics 
card.
Obtain and install the latest device driver for your graphics card from 
the manufacturer’s web site. Also check that DirectDraw acceleration 
is enabled. This can be done by running the program DxDiag.exe (click 
Start - Run and then type dxdiag.exe) Check on the Display tab that 
DirectDraw acceleration is enabled.
Another application is using 
DirectDraw acceleration, 
making this unavailable to the 
AXIS 230.
Close the other application, and then re-open the AXIS 230’s Live View 
page. Examples of other applications that use DirectDraw acceleration 
are: video conferencing software, Web TV, video playback software and 
video editing software. 
Insufficient free memory on 
graphics card for using the 
hardware acceleration 
capabilities. 
Lower the resolution/color depth for the monitor. Right-click on the 
desktop and select 
Properties - Settings.
Poor quality video (image 
hopping, etc.), wrong 
image format (b/w, 
inverted, etc.)
Outdated drivers for graphics 
card.
See “Slow video” above. 
No audio / poor audio.
Faulty connection to external 
mic or audio input device. 
Error in power supply to 
external microphone.
Check connections. If the audio LED flashes or is steady green, then 
audio is reaching the MPEG decoder in the AXIS 230 and is included in 
the stream.
Incorrect settings.
Check that the correct input is selected. Check the input sensitivity. If 
the audio LED flashes or is steady green, then audio is reaching the 
MPEG decoder in the AXIS 230 and is included in the stream.
Error in client.
Check the settings for the client PC’s sound card. If audio is weak or 
distorted, check the master gain setting in the AXIS 230.
Outdated drivers for sound 
card.
Check that you are using the latest device driver for your sound card. 
Check the manufacturer’s web site for new drivers.
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.
