Using IP Surveillance Software (continued)
Playback Program (continued)
Since the program will record the previous start and end time in Time Period
and Events Preview mode. Any time you want to change the period selector
to see another period, 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 data used in Playback Method Selector.
Alert Area Selector
In the Preview Mode, the Playback program only can show the event
information of one alert window at a time. If you want to see the events of the
other two alert area windows, you must change the alert area selector to other
alert 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 zero, when you change the location selector to another one.
Play Control
Speed Indicator
For the play control, a jog dial is used to provide the easiest way to control the
displaying video sequence. Except the Play button, all other buttons can control
the displaying frame in the normal display mode and the selected displaying
frame in the Preview mode.
Play
The Play button is an intelligent play interface. The function of this button
will vary depending on differing circumstances. In the normal display mode,
clicking on the Play button can restart the displaying video sequence. When
in the Preview Mode, if you don't change the data of Period Selector,
clicking on this button only restarts the selected displaying frame. If the
data of the period selector has been changed, clicking on the Play button
will restart all frames to display the first nine events in the new period.
