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.
Please follow the steps below to enable 802.1x setting:
1. Before connecting the camera to the protected network with 802.1x, please
apply a digital certificate from a Certificate Authority (ie. MIS of your company)
which 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 EAP-PEAP or EAP-TLS
as the EAP method. In the following blanks, enter your 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)
Quality of Service refers to a resource reservation control mechanism, which
guarantees a certain quality to different services on the network. Quality of service
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:
The ability to prioritize traffic and guarantee a certain level of performance to the
data flow.
The ability to control the amount of bandwidth each application may use, and thus
provide higher reliability and stability on the network.
