Configuring pre-buffers, motion detection, high-resolution images or high frame rates will affect
the performance of the Axis product.
Poor performance may be caused by heavy network traffic, multiple users accessing the product,
low performance clients, use of features such as motion detection, event handling or uploaded
applications.
Configure your screen to show at least 65000 colors, that is, at least 16 bits. Using only 16 or 256
colors will produce dithering artifacts in the image.
The overlay image may have been positioned incorrectly or may be too large. See
Settings
in the online help for more information.
The privacy mask may have been positioned incorrectly or may be too large.
Lower the image resolution
There is only limited space available for the upload of your own files. Delete existing files to free
up space.
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.
