Axis Communications 231D+/232D+ - Manual (Page 44)

44 AXIS 231D+/232D+ - System Options
Alternative HTTP port - Select this option to manually define an external HTTP port. Enter
the port number in the field provided. If no port is entered here a port number will
automatically be selected when NAT traversal is enabled.
Notes:
• An alternative HTTP port can be used/be active even if NAT traversal is disabled. This is useful if e.g. your
NAT router does not support UPnP and you need to manually configure port forwarding in the NAT router.
• If you attempt to manually enter a port that is already in use, another available port will automatically be
selected.
• When the port is selected automatically it will be displayed in this field. This can be changed by entering a
new port number and clicking Save.
RTSP
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.
FTP
The FTP server running in the AXIS 231D+/232D+ 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
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 that the
network camera is allowed to use on your network. This is a useful function when
connecting your network 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 networking proxy protocol. The AXIS 231D+/232D+ 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 231D+/232D+ 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).
