secondary one, etc. If required, you can manually change the Matrix positions’ ranking in the Setup
tab’s Properties section.
To add Matrix content to a view, do the following on the Setup tab:
1. Drag the System Overview section’s Matrix link to the required position in the view.
2. Release the mouse button over the required position. Note that the position gets a thin
blue border. The blue border indicates that the position
is used for Matrix content; the blue border will also be
evident when using the view on the Browse and Live
tabs.
3. When the Matrix position is selected, you are able to
specify its properties in the Setup tab’s Properties
section:
• Image Quality: The setting determines the
quality of the images when viewed, but also
affects bandwidth usage.
If your Smart Client is used over the internet, over a slow network connection, or if
for other reasons you need to limit bandwidth use, image quality can be reduced on
the server side by selecting e.g. Low or Medium.
When selecting a reduced image quality, images are re-encoded on the server to a
JPEG format along the following lines:
o
Full: The default setting, providing the full quality of the original image.
o
SuperHigh (for megapixel): Re-encoding to an image output width of 640
pixels (VGA) and a JPEG quality level of 25%.
o
High: Re-encoding to an image output width of 320 pixels (QVGA) and a
JPEG quality level of 25%.
o
Medium: Re-encoding to an image output width of 200 pixels and a JPEG
quality level of 25%.
o
Low: Re-encoding to an image output width of 160 pixels and a JPEG
quality level of 20%.
Image height will scale according to the width and the aspect ratio of the original
image.
Your image quality selection will apply for live as well as recorded video, and for
JPEG as well as MPEG. For MPEG, however, only keyframes will be re-encoded
when viewing live video, whereas all images will be re-encoded when viewing
recorded video.
Note: When viewing live video, you can double-click a carousel (or any other
camera position in a view) to enlarge it (see page 58 or 72). When you do this,
video from cameras included in the carousel is by default displayed in full quality,
regardless of your image quality selection. If you want to make sure that the
selected image quality also applies when enlarged, select the Keep when
maximized box, located immediately below the Image Quality setting.
Note: While using a reduced image quality helps limit bandwidth use, it will—due
to the need for re-encoding images—use additional resources on the surveillance
system server.
