Check Network Settings 
The Network Camera can be connected either before or immediately after software 
installation onto the Local Area Network. The Administrator should complete the 
network settings on the configuration page, including the correct subnet mask and IP 
address of gateway and DNS. Ask your network administrator or Internet service 
provider for the detail information. By default the Network Camera requires the 
Administrator to run installation every time it reboots. If the network settings are to 
remain unchanged, disable the Install option. Refer to “Network settings” on the 
System Configuration page for details. If any setting is entered incorrectly and cannot 
proceed to setting up the Network Camera, restore the factory settings following the 
steps in the “Troubleshooting” chapter of the Appendix. 
 
Add Password to Prevent Unauthorized Access 
The default Administrator’s password is blank and the Network Camera initially will 
not ask for any password. The Administrator should immediately implement a new 
password as a matter of prudent security practice. Once the Administrator’s 
password is saved, the Network Camera will ask for the user’s name and password 
before each access. The Administrator can set up a maximum of twenty (20) user 
accounts. Each user can access the Network Camera except to perform system 
configuration. Some critical functions are exclusive for the Administrator, such as 
system configuration, user administration, and software upgrades. The user name for 
the Administrator is permanently assigned as “root”. Once the password is changed, 
the browser will display an authentication window to ask for the new password. Once 
the password is set, there is no provision to recover the Administrator’s 
password. The only option is to restore to the original factory default 
settings.
