9.1.9.11 Advanced Setting Menu (Infrared)
Once inside the menu it is possibile to set the
following parameters:
1. IR Mode: If set to OFF it forces the day mode in
a continuous manner (the switching on of the
illuminator, if present, is carried out by means
of the dusk swtich or by means of the control
on the keyboard). If set to ON it forces the night
mode in a continuous manner. If set to Auto, it
activates the automatic switching of the camera.
2. Night Level: Sets the detection threshold of the
light conditions for the night mode switching.
Lower values correspond to lower lighting
levels.
3. Night Delay: Sets the detection time of the
darkness conditions, expressed in seconds,
before switching to night mode.
4. Day Level: Sets the detection threshold of the
light conditions for the day mode switching.
Lower values correspond to lower lighting
levels.
5. Day Delay: Sets the detection time of the
light conditions, expressed in seconds, before
switching to night mode.
6. Cut Off Filter: If it is set on S, the P&T works
regularly. If it is set on N, the camera does not
switch between night and day mode, but it
works only in day mode. In the event it is set to
N, the illuminator (if available) is switched on
and off according to the settings of the IR Mode
item.
To avoid false switching, we recommend
choosing the higher day switching
threshold and delay values.

This is a dynamic self-configuration menu based on
the choice made and shows the parameters on which
it is possible to operate.
The automatic Day/Night switching mode
of the module is strongly unadvisable
when swinging is subject to repeated
light variations during the night period,
for example during patrol, or due to the
switching on of auxiliary lighting devices.
Those situations can cause numerous
unwanted switching, compromising in this
way the functioning of the module.
