Name Description
Camera name
Displays the name of the selected camera.
To change the camera, click the ellipsis button to open the Select
Camera dialog and select a different camera. This can be useful if
you want to change the camera but keep the settings.
Live Stream
If available, select the live stream that you want to display in the
view. If multiple streams have been set up on the server, you can
select either Default or one of the available stream options. If you
select another option than Default, you will not be able to edit
Image quality or Frame rate settings.
Image quality
Determines the quality of video when viewed, but also affects
bandwidth usage. If your XProtect 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 Low or Medium.
When selecting a reduced image quality, images from the selected
camera are re-encoded to a JPEG format on the surveillance
system server before being sent to the XProtect Smart Client. Re-
encoding takes place along the following lines:
Full: The default setting, providing the full quality of the original
video.
Super high (for megapixel): Re-encoding to an output width of
640 pixels (VGA) and a JPEG quality level of 25%.
High: Re-encoding to an output width of 320 pixels (QVGA) and a
JPEG quality level of 25%.
Medium: Re-encoding to an output width of 200 pixels and a JPEG
quality level of 25%.
Low: Re-encoding to an output width of 160 pixels and a JPEG
quality level of 20%.
Height will scale according to the width and the aspect ratio of the
original video.
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
frames will be re-encoded when viewing recorded video.
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.
Tip: You can quickly reduce the bandwidth usage for all cameras in
the view by reducing the image quality for a single camera, then
clicking the Apply To All button.
