you must first use the Playback Method Selector to change to the mode you want to
use. Otherwise, the Period Selector will revert back to the previous period when you
last changed the playback method.
5.7.1.4 Alert Area Selector
In the Preview mode, the Playback program only shows one type of the alert events
each time. If you want to see the other type of events, you must use the Alert Area
Selector to change to other event type. In the Normal display mode, the alert type
that the Alert Area Selector indicates will be highlighted with a red rectangle. The
Alert Area Selector will be changed to alert window 0 by default settings when you
change the location selector.
5.7.2 Play Control
For Play Control, we used a jog dial, as shown in Figure 5-13, to make it easier to
control video sequence display. Except for the “Play” button, all other buttons can
control the displaying frame in the Normal display mode and the selected displaying
frame in the event Preview mode.

The “Play” button we support here is an intelligent user-interface. The functionality
of this button can vary to fit different circumstances. In the Normal display mode,
click on the “Play” button restarts the displaying video sequence. In the Preview
mode, if you do not change the data of the period selector, clicking on this button
restarts the selected displaying frame. If the data of the period selector has been
changed, clicking on the “Play” button restarts all frames to display the first nine
events in the new period.
