Quality of Service (QoS) lets you prioritize traffic when network congestion occurs by assigning
different service levels to different traffic types.
The following three types of traffic are used by the camera:
• Video (MJPEG over HTTP, RTP/RTSP, RTSP/HTTP)
•Audio
• Management (HTTP traffic, web browsing)
A DSCP (Differentiated Services Code Point) value must be assigned to each traffic type. The
value appears in the traffic’s IP header. When the traffic reaches a DSCP-capable network router
or switch, the DSCP value in the header determines how it is processed (for example, how much
bandwidth is reserved for it).
You can assign each traffic type a DSCP value from 0 to 63. The default setting is 0, which means
that QoS is disabled.

Configuring the DSCP Settings of the Camera
1. Navigate to System Network QoS (see Figure 7-9).
2. Under DSCP Settings, enter a DSCP value from 0 to 63 for Video DSCP, Audio DSCP,
and Management DSCP, and then click Save.
SNMP Settings
The Simple Network Management Protocol (SNMP) lets you monitor and manage the camera
remotely. You can select the version of SNMP that you want to use (SNMPv1, SNMPv2, or
SNMPv3).
SNMPv3 supports an enhanced security system that provides protection against unauthorized
users and ensures the privacy of the messages. Users will be requested to enter the security
name, authentication password and encryption password while setting the camera connections
in the network management system. With SNMPv3, the messages sent between the cameras
and the network management system will be encrypted to ensure privacy.
