Playback Program (continued)
Playback Method Selector
Full Range
If you select this method, the database will be displayed from the
beginning to the end of this location. Any change in the period
selector will have no effect except when you change this selector
to "Time Period."
Time Period
If you change the playback method to "Time Period", you can
modify the start and end time in the period selector. When you
click on the "Play" button in the jog dial, the period you selected
will be displayed.
Since the program will record the previous start and end time in "Time Period"
and "Events Preview" mode, whenever you want to change the period selector
to see the other periods, you must change the playback method selector to the
mode you want to use first. Otherwise, the period selector will revert back to
the previous period set the last time you changed the playback method selector.
Alert Area Selector
In the preview mode, the playback program can show the information of total
events of only one alert window each time. If you want to see the events of the
other two alert area windows, you must change the alert area selector to the
other window numbers. In the normal display mode, the alert window that the
alert area selector indicates will be highlighted with red rectangle if you checked
that window in the settings dialog. The alert area selector will be changed to
alert window 0 by default settings when you change the location selector to
another window.
Play Control
For the play control, the jog dial, shown in the figure below, is used to provide
the easiest method of controlling the video sequence display. All buttons can
control the displaying frame in the normal display mode.
