Network - 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, 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 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.

Network - SMTP (email)

Enter the host names or addresses for your primary and secondary mail servers in the fields provided to
enable event and error email messages from the AXIS 214 PTZ to predefined addresses via SMTP (Simple
Mail Transfer Protocol).

Network - SNMP

The Simple Network Management Protocol (SNMP) allows the remote management of network devices. The
AXIS 214 PTZ can be configured to support SNMP. The three levels of security are:
• SNMP V1 - includes no security.
• SNMP V2c - uses 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/v3
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/v3.
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.
