 QoS (Quality of Service) 
QoS provides differentiated service levels for different types of traffic packets and guarantees 
delivery of priority services during periods of network congestion. Adapting the Differentiated 
Services (DiffServ) model, traffic flows are classified and marked with DSCP (DiffServ Code point) 
values, and as a result receive the corresponding forwarding treatment from DiffServ-capable 
routers.

DSCP Settings 
The DSCP value range is from 0 to 63. The default DSCP value is 0 (DSCP disabled). The camera uses 
the following QoS classes: Video, Audio, and Management. 
  Video DSCP – This class consists of applications such as MJPEG over HTTP, RTP/RTSP and 
RTSP/HTTP. 
Note: 
MJPEG is not supported by Latitude. 
  Audio DSCP – The CP-3211/4221 cameras support audio. 
  Management DSCP – This class consists of HTTP traffic (web browsing). 
Click Save when complete. 
Note: 
To enable this function, make sure the switches/routers in the network support QoS.
