can prevent the camera’s operation being noticed. 

“Automatically restore DO state” The Network Camera will set the DO on when 

events happened, if the administrator configures it properly in the Application page. 

Check this option will restore the DO state to off after specified seconds. 

"Keep current date and time" Click on this to reserve the current date and time 

of the Network Camera. An internal real-time clock maintains the date and time 

even when the power of the system is turned off. 

"Sync with computer time" Synchronize the date and time of the Network 

Camera with the local computer. The read-only date and time of PC is displayed as 

updated.

Administrator. Notice the format in the related fields while doing the entry.   

“Automatic” Synchronize with the NTP server over the Internet whenever the 

Network Camera starts up. It will fail if the assigned time-server cannot be reached. 

“NTP server” Assign the IP address or domain name of the time-server. Leaving 

the text box blank connects the Network Camera to the default time-servers.   

"Time zone" Adjust the time with that of the time-servers for local settings. 

“Update interval” Select hourly, daily, weekly, or monthly update with the time on 

the NTP server.
