3.2.8 QoS, UPnP & ONVIF
[QoS]
The Quality of Service (QoS) is a bandwidth control mechanism that guarantees
delay-sensitive data flows, such as voice and video streams, to achieve a certain amount of
bandwidth in keeping the streaming smooth.
To apply QoS to the camera, all network routers used must support and have QoS enabled.
To enable the QoS on the camera, 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 camera reaches a router, the DSCP value instructs the
router which service level to apply, e.g. the bandwidth amount. This value ranges from 0 to 63,
in decimal format. The default value is 0, which means QoS is disabled.
[UPnP]
UPnP (Universal Plug & Play) is a networking architecture that provides compatibility
among networking equipment, software and peripherals of the 400+ vendors that are part of
the Universal Plug and Play Forum. It means that they are listed in the network devices table
for the operating systems (such as Windows XP) supported by this function. Enabling this
function, you can connect to the camera directly by clicking on the camera listed in the
network devices table.
