AXIS 212 PTZ/-V - Troubleshooting Motion Detection triggers unexpectedly Changes in luminance No audio Incorrect setup No audio or very poor audio quality Audio volume too low/high Volume settings incorrect Poor audio quality Too many users CPU overloaded Unsynchronized audio and video Distorted audio Stuttering audio 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 mistakenly. 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 microphone. 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 Configuration > 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 microphone. 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.

AXIS 212 PTZ/-V - Troubleshooting
For additional assistance, please contact your reseller or see the support pages on Axis Website at www.axis.com/techsup
Motion Detection triggers unexpectedly
Changes in luminance
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.
No audio
Incorrect setup
Check the sound card in the PC. Ensure that the mute button is not pressed and the
volume settings are correct.
No audio or very poor audio quality
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 volume too low/high
Volume settings incorrect
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.
Poor audio quality
Too many users
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
.
CPU overloaded
Reduce the number of listeners and viewers and decrease the image resolution and
compression.
Unsynchronized audio and video
It is recommended that the camera's time setting is synchronized with an NTP Server.
This is enabled under
System Options > Date & Time
.
Distorted audio
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.
Stuttering audio
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.
