2. Connected to its power supply and plugged into an ordinary electrical outlet
3. Assigned an IP Address
Note: If the camera is installed on a network that uses a DHCP server to assign IP
addresses the DHCP feature should be enabled in the camera. See RARP/DHCP/BOOTP

The camera's home page allows viewing live images accessing still images and navigating to
the browser-based configuration pages.
1.5 Configuration Basics
Once the camera is properly installed several features can be customized including image
settings security features and networking capabilities. While some of the camera's features will
need to be customized only for particular situations other features will need to be configured for
all installations. These important features can be configured using the browser-based
configuration page and are discussed in the following places in this manual:
Clock see the Set Date section in Section 2.4.4
Login and privileged passwords see Management Passwords in Section 5.2.2
