Playback Program (continued)
Histogram Area
Inverted region
Dark Region
The histogram area in the normal display (single frame) mode only shows the events' occurred time and
the percentage of motion detection with red bars. If you want to access the histogram area, you must
change the area selection indicator to the histogram area. You can mark one time interval you want to
see with a color-inverted region by dragging your mouse with the left button pressed (as shown above).
When you release the left button, the color-inverted region will be enlarged to the whole histogram area.
This color-inverted region will be the new period the program is going to display. If you change your mind
and don't want to see that period, you can cancel it by just pressing the right button of your mouse with
the left button still pressed. If you click on the left button without dragging it, the action will be the same
as clicking on the pull bar in the same x-axis position. That means the playback system will shift to the
pointed time and show video on the displaying frame. Besides, the dark regions in the histogram area
mean there is no existing video data in that interval. If you click on those regions, nothing will happen
except a warning message will pop up.
Using Tools
In this section, the method of how to use the tools in the control panel (shown in the main playback
window) will be discussed.

The figure below shows the selector tools. They are location selector, period selector for the selection of
the beginning time and the ending time, playback method selector, and alert area selector.
