misunderstandings when playing recorded video. Moreover, the unit will not record if the
time on it is invalid.
The clock can be set by manually synchronizing its time with the time on the PC on which the
configuration utility is running. This should be done when the system is first set up.
Like most clocks, the unit's clock has a tendency to drift slightly over time. Therefore, the
time should be updated at frequent intervals. The time can be updated manually at any time.
The unit can also be configured to update its clock automatically by connecting to an NTP
time server at specified intervals. This option only works when the unit has access to one or
more NTP time servers, either public ones on the internet or locally-installed ones on the
LAN. Public NTP servers can be used free of charge and can be easily accessed when the unit
has internet access.
In addition to the time itself, the general time settings – time zone and daylight savings time
(summer time) – should always be configured correctly. The time zone should be set correctly
before the clock is set. (After setting the time zone, be sure to click Update before manually
updating the time.) Daylight savings time can be activated manually or configured for
automatic activation. It should be activated when daylight savings time begins and
deactivated manually when it ends. When daylight savings time is activated, the time on the
unit clock is set one hour ahead of the time in the selected time zone.
