AXIS 233D - System Options
SOCKS
SOCKS is a networking proxy protocol. The AXIS 233D 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 AXIS 233D 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).
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 bandwidth an
application may use, and thus control over bandwidth races between applications.
The QoS in Axis network video products marks the 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
types of traffic marked by the camera are video, audio, event/alarm and 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. For more information on Quality of Service, please see the Axis support
web at www.axis.com/techsup
SMTP (email)
Enter the host names or addresses for your primary and secondary mail servers in the fields
provided, to enable the sending of notifications and image/video email messages from the
camera to predefined addresses via SMTP.
If your mail server requires authentication, check the box for Use authentication to log in
to this server and enter the necessary information.
