Network - SOCKS
SOCKS is a network proxy protocol. The cameras 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 - SMTP (e-mail)
Enter the host names or addresses for your primary and secondary mail servers in the fields
provided, to enable the sending of event and error e-mail messages from the camera to
predefined addresses via SMTP.
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 con
trol 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
AXIS 210/211 marks the following types of traffic:
•video
•event/alarm
• management network traffic.
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
form, but saved values are always
shown in decimal.
