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, and alarms need to be sent to a destination outside the local network (such as to
the Internet).
SOCKS Settings - Check the checkbox to enable SOCKS. Specify the host name or IP
address of the SOCKS server, the server port and server type (SOCKS4 or SOCKS5). If
SOCKS5 is used, enter a user name and password. List the networks that are not required to
go via the SOCKS server under Local networks.
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 a maintained level of
bandwidth, low latency and few packet losses, for example. 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.
• The ability to control the amount of bandwidth an application may use and thus
control over bandwidth races between applications resulting in greater reliability
in the network.
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 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 the 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. Valid values are integers between 0 and 63. For more information on

SMTP (email)
Enter the host names or addresses for your primary and secondary mail servers in the
fields provided, to enable sending of notifications and image/video email messages from
the camera to predefined addresses via SMTP.
