AXIS 211W - System Options
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, e.g. a maintained level of bandwidth, low latency, no packet losses, etc. The main benefits of a
•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, e.g. reserve a fixed amount of bandwidth for these types of traffic. The types of traffic marked by the camera are video, audio, event/alarm and management network traffic.
QoS DSCP 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 format, 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 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.
UPnP™
The camera includes support for UPnP™, which is enabled by default. If also enabled on your computer, the camera will automatically be detected and a new icon will be added to “My Network Places.”
Note: Check your operating system’s documentation for enabling UPnP™
RTP / MPEG-4
These settings are the port range, IP address, port number (video and audio), and
Bonjour
The AXIS 211W includes support for Bonjour. When enabled, the camera is automatically detected by operating systems and clients that support this.
