the stabilizer functionality has been enabled by providing a VCA Stabilizer license, the option to enable the
stabilizer will appear in the Enable/Disable page. Enabling or disabling the stabilizer will cause a few seconds
pause as the system is re-configured.
4.4.8.1 Stabilizer Configuration
When the stabilizer is enabled an additional configuration page is available under the Stabilizer tab. The
default options are suitable for most applications and you can make use of the stabilizer functionality without
modifying this page. Some installations, however, may benefit from different configurations. The figure shows
the configuration page; the parameters are explained below.
4.4.8.2 Border In-fill
In order to keep the output frames steady and aligned to a reference frame, the output frames are shifted with
respect to the input frames. As the camera moves around, so the output frames are shifted to keep the image
features aligned to previous frames. This results in areas for which there is no image data available. The
Border In-fill combo box lets you select what happens to those areas of the image. There are 5 options
available:
 Fast Fade: [Default] Newer frames are composited on top of older frames. The old frames are faded
away to black quickly. This mode is most suited to PTZ and fixed cameras.
 Slow Fade: Newer frames are composited on top of older frames. The old frames are faded away to
black slowly.
 No Fade: Newer frames are composited on top of older frames. The old frames are not faded away.
Suitable for fixed cameras where there is minimal movement by people and cars around the edge of
the scene.
