SOCKS
SOCKS is a networking proxy protocol. The AXIS 209FD/FD-R/FD-R M12 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).
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 AXIS 209FD/FD-R/FD-R M12 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.

SMTP (email)
Enter the host names (or IP addresses) and port numbers 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.
SNMP
The Simple Network Management Protocol (SNMP) allows remote management of network devices.
Depending on the level of security required, select the version of SNMP to use. The three levels of security
are:
• SNMP V1 - includes no security.
• SNMP V2c - uses very simple security. The community name can be specified as a password for read or
read/write access to all supported SNMP objects. The community is the group of network devices using
SNMP.
• SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled.
