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.
