Network Tab
Use the Network tab to change the encoder’s general network settings, select the Secure Sockets Layer (SSL) settings, enable Secure Shell
(SSH), and configure 802.1x port security settings.
General Network Settings
The General Network page includes programmable and read-only fields for network communication settings. Available settings include the
Hardware Address, Hostname, IP Address, Subnet Mask, Gateway, and DNS Servers.
You can also enable or disable the Dynamic Host Configuration Protocol (DHCP) server from the General Network page. DHCP automatically
assigns an IP address to the device if there is a DHCP server on the network. If DHCP is set to On, the IP address, subnet mask, gateway, and DNS
server settings are read-only text. If DHCP is set to Off, these settings must be manually changed. The default encoder setting for DHCP is On.
SSL Settings
To ensure security on the Internet, all Web browsers provide several security levels that can be adjusted for sites that use SSL technology to
transmit data. SSL encrypts communications, making it difficult for unauthorized users to intercept and view user names and passwords.
SSL requires signed certificates to determine if the Web browser accessing the encoder has the required authentication. The encoder can
generate a certificate signing request (CSR) that can be sent to a certificate authority for a signature (for example, VeriSign
®
), or it can generate
a self-signed certificate using the Generate Self-Signed Certificate option.
SSH Settings
SSH is a user-enabled protocol that allows Pelco Product Support to log on to and service the encoder for advanced troubleshooting purposes.
From this page, users with the appropriate permissions can enable or disable SSH access to the encoder.
802.1x
802.1x is a port security that authenticates devices that want to establish a point-to-point access through a wired or wireless port using
Extensible Authentication Protocol (EAP). This port-based authentication method prevents unauthorized access to a Local Area Network (LAN)
through a physical port. For example, when a device is connected to a network port, the network switch will ask the device for authentication. If
the credential is accepted when the device sends a credential to the network switch, the network switch will open the port for normal use. If
authentication fails, the device is prevented from accessing information on the port.

CHANGING THE HOSTNAME
1. Place your mouse pointer over the Network tab.
2. Select General from the drop-down menu.
3. Click in the Hostname box and highlight the text.
4. Type a user-friendly name into the Hostname box (1 to 21 characters) using any combination of alphanumeric characters. A user-friendly
name makes it easier to recognize the device on the network.
5. Click the Save button to save the settings, or click the Reset button to clear all of the information you entered without saving it.
