Playback method
Display adjustment tool
When you successfully log in to the playback system, the main window will be shown on
the top of the screen and the display resolution will be changed to 1024x768 automatically
(see previous page). There are four main areas , i.e. display area, histogram area, control
area, and status area. There are also three visualized controls , i.e. area selection indicator,
frame selection indicator, and pull bar. These features provide much more convenience while
searching recorded video in the IP surveillance database.
Main Areas
Display Area
The display area is able to show the surveillance database of each camera by time. You can
change the video size through the display adjustment tool and the playback method through
the play control tool. Under the normal display mode as shown in the figure below, you can
just double click on the frame area to change the frame size to 1:1 or 2.25:1.

Histogram Area
The histogram is an interactive control. Not only can you get the event’s location in time domain
and its quantity of the motion percentage, but you can also select a group of events or a period
from the event histogram area and show it on the display area.
Control Area
The control area contains almost all the control selectors and toolboxes you need to browse
the database. These control tools include location selector, period selector, playback method
selector, jog dial, display adjustment tool, searching range adjustment tool, exporting tool,
and system control tool. These tools are discussed in more detail in the section titled “Using
Tools.”
Status Area
The status area is located at the bottom of the main window. It tells you the program status
information including display mode, display size, display speed, exporting file format, and
exporting file name.
Indicators
Area Selection Indicator
In the main playback window, the display area is surrounded by a blue rectangle. This rectangle
is the area selection indicator. This indicator can be set to either display area or histogram
area, as long as you move your mouse cursor to the area you intend to select. When you select
the display area, the display adjustment tool will appear in the control area. If you select the
histogram area, the display adjustment tool will disappear and the searching range adjustment
tool will be shown in the same place of the control area.

Pull Bar
The pull bar is a fast, flexible control for seeking data in the selected time period. It represents
the total length of time in that period. You can pull the indicator on the pull bar to the specific
time-point you would like to view. The displaying video will halt and then restart, playing the
video sequence from the point you selected. If the video sequence has been paused, the
display area will show the point you selected without playing. Note that the pull bar will only
function under the normal display mode.
Settings
After the main window is shown on the screen, you must modify the settings to make it to
work properly. Click on the “Settings” button, shown below, in the system control tool, and the
setting dialog will appear on the screen.

Database location
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.
The items in the settings windows are:
Modulation Mode:
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.
AVI file location
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.
Snapshot file location
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.
