[QoS Settings]
The Quality of Service (QoS) is a bandwidth control mechanism that guarantees
delay-sensitive data flows such as voice and video streams, obtain a certain amount of
bandwidth to keep the streaming smooth.
To apply QoS to the GV-Compact DVR V2, all network routers must support QoS and QoS
must be enabled on these devices. To enable the QoS on the GV-Compact DVR V2, enter a
Differentiated Services Code Point (DSCP) value. This value is a field in an IP packet that
enables different levels of services for the network traffic. When the video stream from the
GV-Compact DVR V2 reaches a router, the DSCP value will tell the router what service level
to be applied, e.g. the bandwidth amount. This value ranges from 0 to 63 in decimal format.
The default value is 0, meaning QoS is disabled.
