Network – QoS
Quality of Service (QoS) provides the means to guarantee a certain level of a specified resource to
selected traffic on an IP network. Quality can be defined as e.g. a maintained level of bandwidth,
low latency, no packet losses, etc.

DSCP Setting
For each of the supported types of network traffic, enter a value for the DSCP (Differentiated
Services Code Point) field in the data packet's IP header. This value marks the network traffic so
that network routers know which service(s) to apply to the packet, for example, the amount of
bandwidth reserved for the type of traffic.
The QoS in the HDG-M120 Series Network Camera marks the data packets belonging to various
types of network traffic originating from the unit. QoS-enabled network routers and switches then
use these markings to apply particular treatment to these types of traffic, for example, to reserve a
fixed amount of bandwidth.
The types of traffic that can be marked are video, audio, event/alarm traffic and management
network traffic.
NOTES
The main benefits of a QoS-aware network can be summarized as:
