Section 3 - Configuration
The most important item in the settings dialog is the database location setting. You must
set it to the directory that contains the surveillance database to make the program to work
properly.
This sets the directory where exported
AVI files will be stored. Exported AVI files will be
stored in the sub-directory (camera name) under the directory you set here.
This sets the directory where bitmap files will be stored when you use the snapshot to
export them. Exporting bitmap files will be stored in the sub-directory (camera name)
under the directory you set here.
The modulation mode cannot be changed. This depends on how you recorded the video
sequence in the monitor program. If you select the wrong mode, the video shown in the
display area will become distorted. If you have chosen the wrong modulation mode, you
may open the settings dialog again, change to the correct mode, and restart the playback
program. The display will now be normal.
The items in the settings windows are:
Database Location:
AVI File Location:
Snapshot File Location:
Modulation Mode:
Normal (Single Frame) Mode
While in the normal (single frame) display mode, you can change the video currently displayed by:
1) Changing the database path for retrieving another one in the settings dialog of “System Control” tool.
2) Changing the location selector to another location in control area.
3) Changing the playback method selector to “Full Range.”
4) Changing the playback method selector to “Time Period.”

Under the normal display (single frame) mode, you can use all the tools provided with the playback program, except
the page control. In this mode, the two labels under the pull bar show the starting and the ending time of the interval
individually (as shown below).

Histogram Area
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 below). 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.
Selector Tools
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.

Section 3 - Configuration
Location Selector
The location selector is a control that lets you select the camera you want to see (refer to the figure above). The location
name is the same as the camera name (text on video) unless you have specified otherwise.
Period Selector
Period selector provides you a precise way to choose the start time and the end time of a new period. The end time
must be later than the start time. After you provide the correct start and end time, clicking on the “Play” button in the
jog dial will play the new period in the display area with changing the period start and end time label. Besides, the pull
bar and histogram area will change, too. If the selected period is not present in the database, the data in the period
selector will change to the previous correct start and end time, and a warning message will be displayed.
Playback Method Selector
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.
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.”
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.
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.

Section 3 - Configuration
The supported “Play” button is an intelligent play user-interface. The
functionality of this button can vary to fit different circumstances. In
the normal display mode, clicking on the “Play” button can restart the
displaying video sequence.
When you want to stop the displaying video sequence, you can click
on the “Stop” button. Note that once you press the “Stop” button, the
start point will be reset to the start of the present period.
The “Pause” button provides you a way to pause the video sequence
display. When the displaying video is paused, click on the “Pause”
button again to resume the video display.
This button is only valid when the displaying video sequence is paused. It will display the next frame in
that period when you click on the “Forward” button one time.
The camera supports a maximum of x16 fast forward play and minimum of /16 slow forward play. This
function helps you browse the surveillance database with more flexibility. If you want to change the
playing speed, you just need to move the speed indicator. To increase playing speed, move the indicator
in the clockwise direction. And to decrease playing speed, move it in the counterclockwise direction.
The current speed that is set will be shown in the second column of status area.
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.
Play:
Stop:
Pause/Resume:
Forward:
