52 Axis video server - System optionsHTTPSThe default HTTPS port number (443) can be changed to any port within the range1024-65535. This is useful for e.g. simple port mapping.NAT 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.RTSPThe RTSP protocol allows a connecting client to start an MPEG-4 stream. Enter the RTSPport number to use. The default setting is 554, and the allowed port range is 1024-65535.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 that thevideo server is allowed to use on your network. This is a useful function when connectingyour video server 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 maycreate problems for individual video streams if the maximum value is less than the sum of the bit rates setfor the video streams.For more information, please see the online helpSOCKSSOCKS is a networking proxy protocol. The Axis video server can be configured to use aSOCKS server to reach networks on the other side of a firewall/proxy server. Thisfunctionality is useful 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 localnetwork (e.g. to the Internet).SMTP (email)Enter the host names or addresses for your primary and secondary mail servers in thefields provided, to enable event and error email messages from the video server topredefined addresses, via SMTP.If the mail server requires SMTP authentication, check the box for Use authentication tolog in to this server and enter the user name and password used for logging in. Severaldifferent methods of authentication are available. See the online help for moreinformation.
