Motion detection is based upon changes in luminance in the image. This means that
if there are sudden changes in the lighting, motion detection may be triggered mis-
takenly. Lower the sensitivity setting to avoid problems with luminance.
Check the sound card in the PC. Ensure that the mute button is not pressed and the
volume settings are correct.
Check that the correct Audio Input source is selected under Setup > Audio > Source.
Select Microphone for the internal microphone or for a connected external micro-
phone. Select Line for a connected line in source.
The volume of the microphone is either too high or too low. Change the volume for
the microphone in the toolbar on the Live View page.
Too many users/clients connected to the camera may affect the sound quality
adversely. Try limiting the number of clients allowed to connect under Basic Config-
uration > Users.
Reduce the number of listeners and viewers and decrease the image resolution and
compression.
It is recommended that the camera's time setting is synchronized with an NTP Server.
This is enabled under System Options > Date & Time.
Check that the correct Audio Input source is selected under Setup > Audio > Source.
Select Microphone for the internal microphone or for a connected external micro-
phone. Select Line for a connected line in source.
Audio break-up (stuttering audio) can be reduced using the Audio Buffer in AXIS
Media Control. Right-click the video image and select 'Settings' and 'Audio'. A higher
audio buffering level will reduce audio break-up, but may introduce a noticeable lag
in audio transmission.
