[UPnP Settings] 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 system (such as Windows XP) supported by this
function. Enabling this function means you can connect to the camera
directly by clicking on the camera listed in the network devices table.
[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 camera, all network routers must support QoS and
QoS must be enabled on these devices. To enable the QoS on the camera,
select 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 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.
[Network Connection Check Settings] The camera checks for Internet
connection, and reboots when it is disconnected from the Internet. This
function is enabled by default.
Note: If you do not intend to connect the camera to the network,
disable this function to prevent automatic reboot.
