32 AXIS 207 - System Options
FTP
The FTP server running in the AXIS 207 enables the upload of e.g. new firmware, user
applications, etc. Check the box to enable the service.
RTSP
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box to
enable the RTSP server and enter the RTSP port number to use. The default setting is 554.
Note that MPEG-4 streams will not be available if this is not enabled.
Network Traffic
Connection Type - The default setting is Auto-negotiate, which means that the correct
speed is automatically selected. If necessary, you can set the connection speed by selecting
it from the drop-down list.
For more information, please see the online help.
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 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
cameras marks the following types of traffic:
• live video
• live audio
• event/alarmtraffic
• 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.
