Use the Network tab to change the camera’s general network settings, select the Secure Sockets Layer (SSL) settings, enable Secure Shell (SSH), 
configure 802.1x port security and select Simple Network Management Protocol (SNMP) 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 camera setting for DHCP is On. 

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 camera has the required authentication. The camera 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 is a user-enabled protocol that allows Pelco Product Support to log on to and service the camera for advanced troubleshooting purposes. 
From this page, users with the appropriate permissions can enable or disable SSH access to the camera.

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.

SNMP is an application layer protocol used to manage TCP/IP-based networks from a single workstation or several workstations. The camera 
supports SNMP versions 2c and 3 and can be configured to send data using a trap.
