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
configurations 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
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 Video Recorder, slave and
aux. output.
External Day/Night Switch
You can install an optional Alarm/Action box to
activate the Day/Night Switch. When the External Day/
Night Switch is used, the Day/Night Switch on the
monitor 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 is OFF Observation System off
LED is Green Observation System is in DAY
MODE
LED is Amber Observation System is in NIGHT
MODE with the screen display
function disabled.
LED is Red Observation System is in NIGHT
MODE with the screen display
function enabled.
