QoS stands for Quality of Service, which can solve the problem of network delay and network
congestion efficiently. Configuration steps are as follows:
1) Check "Enable" to enable QoS function;
2) Configure "DSCP for Audio/Video"
and “DSCP Management”, ranging 0 ~ 63;
Note: There are 64 DSCP priority levels (0-63), which identify different priority levels of
packets, 0 with the lowest priority and 63 with the highest. Select and keep packets according
to their priority levels. Different levels occupy different bandwidths with different packet loss
rates during network congestion, thus the quality of service is ensured.
3) Click "

UPnP
Picture 6-12 UPnP
Note: For a camera in an Ethernet, UPnP function can make gateway or router perform
auto-port-mapping which maps the camera monitor port from gateway or router to the
Ethernet device, thus the firewall module on the gateway or router starts to open this port to
other PCs on the internet.
