44AXIS Q19 Series - System OptionsUse manually selected NAT router - Select this option to manually select a NAT router and enter the IP address for the routerin the field provided.If a router is not manually specified, the network camera automatically searches for NAT routers on your network. If morethan one router is found, the default router is selected.Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in the fieldprovided. If no port is entered here a port number is automatically 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 your NAT router doesnot 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 is automatically selected.• When the port is selected automatically it is displayed in this field. To change this enter a new port number and clickSave.FTPThe FTP server running in the network camera enables the upload of new firmware, and user applications. Check the box toenable the service.RTSPThe RTSP protocol allows a connecting client to start an H.264 stream. Check the box to enable the server and enter the RTSPport number to use. The default setting is 554. Note that H.264 video streams will not be available if this service is notenabled.SOCKSSOCKS is a networking proxy protocol. The network camera can be configured to use a SOCKS server to reach networks on theother side of a firewall/proxy server. This functionality is useful if the network camera is located on a local network behind afirewall, and notifications, uploads, alarms, and such need to be sent to a destination outside the local network (such as theInternet). See the online help for more information.QoS (Quality of Service)Quality of Service (QoS) guarantees a certain level of a specified resource to selected traffic on a network. Quality can bedefined as a maintained level of bandwidth, low latency, and no packet losses. The main benefits of a QoS-aware network canbe 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 bandwidth an application may use, and thuscontrol over bandwidth races between applications.The QoS in Axis network video products marks the data packets for various types of network traffic originating from theproduct. This makes it possible for network routers and switches to reserve a fixed amount of bandwidth for these types oftraffic. The network camera marks the following types of traffic:• video• audio• event/alarm• management network trafficQoS Settings - For each type of network traffic supported by your Axis network video product, enter a DSCP (DifferentiatedServices Codepoint) value. This value is used to mark the traffic’s IP header. When the marked traffic reaches a network routeror switch, the DSCP value in the IP header tells the router or switch the type of treatment to apply to this type of traffic, forexample, how much bandwidth to reserve for it. Note that DSCP values can be entered in decimal or hex form, but savedvalues are always shown in decimal.For more information on Quality of Service, please see Axis support web at www.axis.com/techsup
