AXIS 212 PTZ/-V - System Options Maximum bandwidth - Specify, in Mbit/s or Kbit/s, the maximum bandwidth that AXIS 212 PTZ/-V is allowed to use on your network. This is a useful function when connecting AXIS 212 PTZ/-V to busy or heavily loaded networks. The default setting is Unlimited. For more information, please refer to the online help. SOCKS SOCKS is a networking proxy protocol. AXIS 212 PTZ/-V 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 AXIS 212 PTZ/-V 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 (for example, to the Internet). QoS (Quality of service) 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 for example, a maintained level of bandwidth, low latency, no packet losses, etc. 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 bandwidth an application may use, and thus control over bandwidth races between applications. The QoS in Axis network video products marks the data packets for various types of network traffic originating from the product. This makes it possible for network routers and switches to for example, reserve a fixed amount of bandwidth for these types of traffic. The following types of traffic are marked: • live video • live audio • event/alarm traffic • management network traffic QoS Settings For each type of network traffic supported by your Axis network video product, enter a DSCP (Differentiated Services Codepoint) value. This value is used to mark the traffic's IP header. When the marked traffic reaches a network router or switch, the DSCP value in the IP header tells the router or switch which type of treatment to apply to this type of traffic, for example, how much bandwidth to reserve for it. Note that DSCP values can be entered in decimal or hexadecimal form, but saved values are always shown in decimal. For more information on Quality of Service, please see the Axis support web at www.axis.com/techsup SMTP (email) Enter the host names or addresses for your primary and secondary mail servers in the fields provided, to enable the sending of notifications and image/video email messages from the camera to predefined addresses via SMTP. If your mail server requires authentication, check the box for Use authentication to log in to this server and enter the necessary information. SNMP The Simple Network Management Protocol (SNMP) allows remote management of network devices. Depending on the level of security required, select the version of SNMP to use. The three levels of security are: • SNMP V1 - includes no security. • SNMP V2c - uses very simple security. The community name can be specified as a password for read or read/write access to all supported SNMP objects. The community is the group of network devices using SNMP. • SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled. 36
