GOV Settings
The GOV structure describes the composition of the video stream and setting the GOV-length to a higher value saves
considerably on bandwidth but may have an adverse effect on image quality.
Bit Rate Control
The bit rate can be set as
Variable Bit Rate
(VBR) or
Constant Bit Rate
(CBR). VBR adjusts the bit rate according to the image
complexity, using up bandwidth for increased activity in the image, and less for lower activity in the monitored area.
CBR allows you to set a fixed
Target bit rate
that consumes a predictable amount of bandwidth. As the bit rate would usually
need to increase for increased image activity, but in this case cannot, the frame rate and image quality are affected
negatively. To partly compensate for this, it is possible to prioritize either the frame rate or the image quality whenever the bit
rate needs to be increased. Not setting a priority means the frame rate and image quality are equally affected.
Note:
To determine a reasonable bit rate, go to
Setup > Video & Audio > Video Stream > Image
, check the
Include
checkbox
and enter the code
#b
in the
Include text
: field. The current bit rate is displayed as a text overlay on the
Live View
page.
