AXIS 225FD - System Options
Network - SOCKS
SOCKS is a network proxy protocol. The camera can be configured to use a SOCKS server
to reach networks on the other side of a firewall/proxy server. This functionality is useful
if the camera is located on a local network behind a firewall, but notifications, uploads,
alarms, etc., need to be sent to a destination outside the local network (e.g. to the Internet).
Network - QoS (Quality of Service)
Quality of Service (QoS) provides the means to guarantee a certain level of a specified
resource to selected traffic on a network. Quality can be defined as e.g. a maintained level
of bandwidth, low latency, no packet losses, etc. The main benefits of a QoS-aware
network can be summarized as:
• the ability to prioritize traffic and thus allow critical flows to be served before
flows with lesser priority
.
• greater reliability in the network, thanks to the control of
the amount of band-
width an application may use, and thus control
over bandwidth races between
applications.
The QoS in Axis network video products marks th
e data packets for various types of
network traffic originating from the product. This makes it possible for network routers
and switches to e.g. reserve a fixed amount of bandwidth for these types of traffic. The
following types of traffic are marked:
• live video
• live audio
• event/alarm traffic
• management network traffic
It is important to remember that to be able to use
QoS, your network must be properly
configured. If you are unsure as to whether your network is QoS aware, please check with
your network administrator.
QoS Settings
For each type of network traffic supported by your Axis network video product, enter a
DSCP (Differentiated Services Codepoint) value. This value is used to mark the traffic’s IP
header. When the marked traffic reaches a network router or switch, the DSCP value in the
IP header tells the router or switch which type of treatment to apply to this type of traffic,
for example, how much bandwidth to reserve for it.
Note that DSCP values can be entered in decimal or hex
adecimal form, but saved values
are always shown in decimal.
