AXIS 207/207W - Troubleshooting 43

Slow image update

Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame rates,

 

etc, will reduce the performance of the camera.

 

 

Poor performance

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.

 

 

Poor quality snapshot images

 

 

 

Screen incorrectly configured on your

In Display Properties, configure your screen to show at least 65000 colors, i.e. at least

workstation

16-bit. Using only 16 or 256 colors will produce dithering artifacts in the image.

 

 

Browser freezes

 

 

 

Netscape 7.x or Mozilla 1.4 (or later)

Lower the image resolution.

can sometimes freeze on a slow com-

 

puter

 

 

 

Problems uploading files

 

 

 

Limited space

There is only limited space available for the upload of your own files. Try deleting existing

 

files to free up space.

 

 

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 mistakenly.

 

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.

 

 

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 Configuration > Users.

 

 

CPU overloaded

Reduce the number of listeners and viewers and decrease the image resolution and com-

 

pression.

 

 

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.
