AXIS M1011/M1011-W/M1031-W - System Options
QoS (Quality of Service)
Quality of Service (QoS) guarantees a certain level of a specified resource to selected traffic on a network. Quality can be
defined as a maintained level of bandwidth, low latency, and no packet losses. 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 reserve a fixed amount of bandwidth for these types of
traffic. The network cameras mark the following types of traffic:
•video
•audio
•event/alarm
• 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 the 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 hex form,
but saved values are always shown in decimal.

SMTP (email)
Enter the host names (or IP addresses) and port numbers 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 authen
tication, check the box for Use authentication to log in to this server and enter the
necessary information. See the online help for more 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 the group of network devices using SNMP.
• SNMP V3 - provides encryption and secure passwords. HTTPS
must be enabled.
UPnP™
The network camera includes support for UPnP™. This is enabled by default, and the network camera then is automatically
detected by operating systems and clients that support this protocol.
RTP/H.264 & MPEG-4
These settings are the port range, IP address, port number (video and audio), and Time-To-Live value to use for the video
stream(s) in multicast H.264/MPEG-4 format. Only certain IP addresses and port numbers should be used for multicast
streams. For more information, please see the online help .
