7.3.3.2 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 CF-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.
