BAS IC OPERATION
Operation and programming of the system is performed
through On Screen Display (OSD) menus. With these
easy to use menus you can setup the system to your own
needs.
2.1 OPERATOR CONTROLS

tem Multiplexer is as follows:
2.1.1 Power Switch

operation.
•

monitor to switch the system on/off. A LED on the
front of the monitor indicates the system mode.

(x.xx = version number)
After a while the camera image appears on the monitor
screen.
2.1.2 Day/Night
The system can be set in two different modes, DAY
Mode and NIGHT Mode. These two modes are set up
in the System setup menus and allow different configu-
rations for day operation and night-time operation. For
example, in night-time operation, the display picture
can be switched off, alarm inputs enabled, etc.
Day mode
In the day mode the image and sound of the monitor
are switched on and the day alarm profile is enabled.
Night mode
In the Night mode, the night alarm profile is enabled.
Availability of image and audio is configured in the sys-
tem settings.
A moon symbol is visible on the screen when you are in
night mode.
Note
If the video and audio of the monitor are set off in the
night mode, the camera continues to transmit images
and sound to the Video Recorder, slave and aux. out-
put.
External Day/Night Switch
You can install an optional Alarm/Action box to acti-
vate the Day/Night Switch. When the External Day/
Night Switch is used, the Day/Night Switch on the mon-
itor and Remote Control are deactivated.
Remark
When switching over from day to night mode, the
actual night profile is activated when the programmed
exit delay time has expired. The LED color changes
accordingly. An alarm generated during night mode will
be processed by the system after the entry delay time
has expired. If the system is switched from night to day
mode during the entry delay time the alarm will not be
processed. Exceptions are special alarms, like tamper
and system alarms, which will always be processed.
LED indication is as follows:
