Configuration
The 802.1x standard is designed to enhance the security of local area networks,
which provides authentication to network devices (clients) attached to a network
port (wired or wireless). If all certificates between client and server are verified, a
point-to-point connection will be enabled. If authentication fails, access on that port
will be prohibited. 802.1x utilizes an existing protocol, the Extensible Authentication
Protocol (EAP), to facilitate communication.
Follow the steps below to enable 802.1x setting:
1. Before connecting the camera to the protected network with 802.1x, apply a
digital certificate from a Certificate Authority (i.e. MIS of your company) that can
be validated by a RADIUS server.
2. Connect the camera to a PC or notebook outside of the protected LAN. Open the
configuration page of the camera as shown below. Select an EAP method, EAP-
PEAP or EAP-TLS. In the fields below, enter your Identity (ID) and Password
issued by the CA, then upload related certificate(s).
3. When all settings are complete, move the camera to the protected LAN by
connecting it to an 802.1x enabled switch. The devices will then start the
authentication automatically.
QoS (Quality of Service) Defined:
QoS refers to a resource reservation control mechanism, which guarantees a
certain quality to specific services on the network. QoS guarantees are important
if the network capacity is insufficient, especially for real-time streaming multimedia
applications. Quality can be defined as, for instance, a maintained level of bit rate,
low latency, no packet dropping, etc.
The following are the main benefits of a QoS-aware network:
ƒ The ability to prioritize traffic and guarantee a certain level of performance to the
data flow.
ƒ The ability to control the amount of bandwidth each application can use, and thus
provide higher reliability and stability on the network.
Requirements for QoS:
To utilize QoS in a network environment, the following requirements must be met:
• All network switches and routers in the network must include support for QoS.
• The network video devices used in the network must be QoS-enabled.
