screen.
2.1.2 Day/Night
The system can be set in two different modes, DAY
Mode and NIGHT Mode. These two modes are setup
in the System setup menus and allow different
configurations for day operation and night-time
operation. For example, at 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
system settings.
A moon symbol is visible on the screen when you are in
night mode.
Note that 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 VCR, slave and aux. output.
Remark: By switching over from day to night the actual
night profile is activated after the programmed exit delay
time is expired. The LED colour changes accordingly.
An alarm generated in night mode will be processed by the
system after the entry delay time is expired. If the system
switches over from night to day during this entry delay
time a generated alarm will not be processed. Exceptions
are special alarms, which always will be processed .
