AXIS 240Q - System Options
NAT traversal
Use NAT traversal when your video server is located on an intranet and you want to make
it available from the other side of a NAT router.
FTP
The FTP server running in the AXIS 240Q enables the upload of e.g. new firmware, user
applications, etc. Check the box to enable the service.
Network Traffic
The default setting is Auto-negotiate which means that the correct speed is automatically
sele
cted. If necessary, you can set the connection speed by selecting it from the drop-down
list.
Maximum bandwidth
- Specify, in Mbit/s or kbit/s, the maximum bandwidth the AXIS
240Q is allowed to use on your network. This is a useful function when connecting the
video server to busy or heavily loaded networks. The default setting is Unlimited.

SOCKS
SOCKS is a networking proxy protocol. The AXIS 240Q 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 video server 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 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:
• event/alarm traffic
• management network traffic.
