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 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, 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.
Traps for SNMP v1/v2
Traps are used by the camera to send messages to a management system for important events or status changes.
These settings are used with SNMP v1/v2.
You can activate trap reporting, enter the IP address of the management server, and choose the trap community
to use when sending a trap message to the management system.
