

  Enable 

auto stream size: The Auto Stream Size feature dynamically adjusts the stream sizes of video 

feeds from network cameras in order to reduce CPU load and bandwidth consumption. 

  
  It is often the case that in surveillance deployments the physical dimensions of monitors, the 

effectiveness of visual stimulus, and the operators' regions of interest can all be very limited. 

Streaming large-size videos at all times will be a waste of bandwidth and system computing power. 

CIF and VGA size videos are usually sufficient for the operators of a surveillance software. 

  

When enabled, your LiveClient station automatically requests smaller-size streams as video feeds 

from the network cameras. 

When the size of view cells is manually expanded, a VAST server requests a different larger stream. 

Facts about Auto Stream Size:
•  The LiveClient utility automatically adjusts stream selection according to the size of view cells, no 

user's configuration is required. 

•  The frame size of stream #1 is user-configurable. 
•  Under no circumstances should you disable the Auto Stream Size function.
•  Stream jump takes place on the display of all connected cameras once the function is enabled.
•  If users configured a region of interest before the Auto Stream Size function is applied, e.g., via 

the ePTZ control, the view cell might display a different live view.   



  Enable de-interlace function: Select this option if your connected device does not support de-interlace 

function. For example: VS7100.

Display Settings

Please do not disable the Auto stream size option. Disabling Auto stream size can cause a 

performance problem with the system. Today's megapixel cameras produce high resolution 

videos that, if not properly processed, can overstress the system.
