AXIS 212 PTZ - Troubleshooting

 

 

Problem with AMC.

To enable the updating of video images in Microsoft Internet Explorer, set your browser to allow ActiveX con-

(Internet Explorer only)

trols. Also, make sure that AXIS Media Control (AMC) component is installed on your workstation.

 

 

Installation of additional ActiveX component

Configure your camera to use a Java applet for updating the video images under

restricted or prohibited

Live View Config > Layout > Default Viewer for Internet Explorer. See the online help for more information.

 

 

Video/Image problems, general

 

 

 

Image too dark or too light

Check the video image settings. See the online help on Video and Image Settings.

 

 

Decreased image quality in zoomed in view

The camera requires sufficient light to deliver good image quality in zoomed in view. Better indoor lighting will

 

increase image quality.

 

 

Missing images in uploads

This can occur when trying to use a larger image buffer than is actually available. Try lowering the frame rate or

 

the upload period.

 

 

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 perfor-

 

mance clients, use of features such as Motion Detection, Event handling, Image rotation other than 180 degrees.

 

 

Poor quality snapshot images

 

Screen incorrectly configured on your worksta- tion

No Pan Tilt Zoom movement

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.

Problem with Quicktime

Browser freezes

Limited click-in-image functionality in Quicktime, use the pan, tilt, zoom toolbars instead.

Netscape 7.x or Mozilla 1.4 (or later) can some- Lower the image resolution. times freeze on a slow computer

Problems uploading files

Limited space

Motion Detection triggers unexpectedly

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

Changes in luminance

No 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.

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

Check that the correct Audio Input source is selected under Setup > Audio > Source. Select Microphone for the

very poor audio quality

internal microphone or for a connected external microphone. 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 tool-

 

bar 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 compression.

 

 

Unsynchronized audio and video

It is recommended that the camera's time setting is synchronized with an NTP Server. This is enabled under Sys-

 

tem 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 microphone. 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.
