Open the Time and Date dialog to set the camera's date, time, time zone and time server settings.
The operating system's clock is synchronized with the real-time clock at boot time and every 6 hours. To avoid differences caused by minor offsets of the real-time clock, the camera can synchronize the real-time clock using an external time server. You can choose between these two protocols:
NTP (RFC 1305) (Network Time Protocol): This protocol can be used with one or more time servers in the Intranet or the Internet (e.g.
ptbtime1.ptb.de), that provide the NTP (RFC 1305) service. Since this protocol requires a permanent connection to the time server, it is not feasible for cameras that can only access the time server using an ISDN connection.
time-a.nist.gov), that provides the Time Protocol service. You should set this protocol if the camera only has an ISDN dial-out connection.
|Note:||The camera has to be able to access the time server using the local network or an ISDN connection.|
|Caution!||Never use the NTP (RFC 1305) protocol if the camera can only access the time server using an ISDN connection. The limits set in Dial-Out Accounting could be reached very quickly. The camera will stop sending messages and will not transmit any images!|
In order to set the date manually, enter the date in the respective text boxes using the format
Enter the time in the respective text boxes according to the selected time zone using the format
Click on the corresponding Set button to the right of a text box to set the camera clock.
|Your Computer||Click on the Set button to adjust the camera clock the the date and time of your computer.|
|Time Server||Click on the Set button in this line to copy the date and time of the specified time server to the camera.|
Select the correct time zone for the camera location.
NTP (RFC 1305)
To synchronize the camera with a time server providing NTP (RFC 1305, Network Time Protocol), do the following:
Click on the view link to see the output of the camera's NTP client. The information is displayed in different colors: If the time server can be reached, the NTP client are amber, if the camera clock is synchronized, the output is green. Note: only one time server will be used. Be patient—synchronizing the clock using NTP may take some time.
To use the camera as a timeserver for other cameras do the following:
Time Protocol (RFC 868)
To synchronize the camera with a timeserver providing the Time Protocol (RFC 868), do the following:
|Hourly Sound||Select one of the sound files that have been stored using the Manage Audio Messages dialog in order to play back the file at every full hour.|
Proceed as follows to deactivate a time server:
Click on the Set button to activate your settings and to save them until the next reboot of the camera.
Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
