Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame rates,
etc, will reduce the performance of the camera.
Poor performance may be caused by e.g. heavy network traffic, multiple users accessing
the unit, low performance clients, use of features such as Motion Detection, Event han-
dling, Image rotation other than 180 degrees. For the AXIS 207W, a poor wireless environ-
ment may also affect performance.
In Display Properties, configure your screen to show at least 65000 colors, i.e. at least
16-bit. Using only 16 or 256 colors will produce dithering artifacts in the image.
Lower the image resolution.
There is only limited space available for the upload of your own files. Try deleting existing
files to free up space.
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.
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 com-
pression.
It is recommended that the camera's time setting is synchronized with an NTP Server. This
is enabled under System Options > Date & Time.
