Axis Communications Axis 211A - Manual (Page 49)

49 AXIS 210A/211A - System Options
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Enter the RTSP
port number to use. The default setting is 554.
Network Traffic
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.
Maximum bandwidth - Specify, in Mbit/s or kbit/s, the maximum bandwidth the AXIS
210A/211A is allowed to use on your network. This is a useful function when connecting
the camera to busy or heavily loaded networks. The default setting is Unlimited.
Note:
When using MPEG-4 as the video format, remember that setting a maximum bandwidth value here may
create problems for individual video streams if the maximum value is less than the sum of the bit rates set
for the video streams.

SOCKS
SOCKS is a network proxy protocol. The cameras 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, and
alarms need to be sent to a destination outside the local network (such as to the Internet).
QoS
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, no packet losses, and so on. 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.
