Ensure that your graphics card is using the latest driver. The latest drivers can usually be
downloaded from the manufacturer's website.
Modify the settings for your graphics adapter. Refer to the adapter's documentation for more
information.
See Performance Considerations on page 68.
Reduce the number of applications running on the client computer.
Limit the number of simultaneous viewers.
Check with the network administrator that there is enough bandwidth available.
Check in the AMC Control Panel (H.264 tag) that video processing is NOT set to Decode only
key frames.
Lower the image resolution.
Check the video stream and camera settings under Setup > Video & Audio > Video Stream and
Setup > Video & Audio > Camera Settings.
Motion detection is based on changes in luminance in the image. This means that if there are
sudden changes in the lighting, motion detection may trigger mistakenly. Lower the sensitivity
setting to avoid problems with luminance.
Check the sound card in the computer. Ensure that mute is not selected and that the volume
settings are correct.
Check that Enable audio support is selected under Setup > System Options > Security > Audio
Support.
Check that the correct Audio Input source is selected under Setup > Video & Audio > Audio
Settings.
Reduce the number of listeners and viewers. Decrease image resolution and compression.
Synchronize the product's date and time settings with an NTP server. Go to Setup > System
Options > Date & Time.
Check that the correct Audio Input source is selected under Setup > Video & Audio > Audio
Settings.
Feedback loops might appear in full-duplex mode. Try moving the microphone or the speaker, or
use half-duplex mode instead.
A storage disruption alarm is sent if a storage device is unavailable, removed, full, locked or if other
read or write problems occur. To identify the source of the problem, check the System Log under
System Options > Support > Logs & Reports. Depending on the problem, it might be necessary to
re-mount the storage device.
For information on how to set up a storage disruption alarm, see Events on page 38.
