41AXIS 240Q - System OptionsNAT traversalUse NAT traversal when your video server is located on an intranet and you want to makeit available from the other side of a NAT router.FTPThe FTP server running in the AXIS 240Q enables the upload of e.g. new firmware, userapplications, etc. Check the box to enable the service.RTSPThe RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box toenable the RTSP server and enter the RTSP port number to use. The default setting is 554,and the allowed port range is 1024-65535. Note that MPEG-4 streams will not be availableif this is not enabled.Network TrafficThe default setting is Auto-negotiate which means that the correct speed is automaticallyselected. If necessary, you can set the connection speed by selecting it from the drop-downlist.Maximum bandwidth - Specify, in Mbit/s or kbit/s, the maximum bandwidth the AXIS240Q is allowed to use on your network. This is a useful function when connecting thevideo server to busy or heavily loaded networks. The default setting is Unlimited.For more information, please see the online helpSOCKSSOCKS is a networking proxy protocol. The AXIS 240Q can be configured to use a SOCKSserver to reach networks on the other side of a firewall/proxy server. This functionality isuseful 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 theInternet).QoS (Quality of service)Quality of Service (QoS) provides the means to guarantee a certain level of a specifiedresource to selected traffic on a network. Quality can be defined as e.g. a maintained levelof bandwidth, low latency, no packet losses, etc. The main benefits of a QoS-awarenetwork can be summarized as:• The ability to prioritize traffic and thus allow critical flows to be served beforeflows 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 betweenapplications.
