3.3.3 Day/Night Tab
Note: The settings on this tab will only be adjustable on day/night models of the camera. On non-
day/night cameras, the parameter values will be indicated as "Fixed" or "Not Available".
Section 6 on page 89 provides detailed information about how the camera's day/night functionality
works. Basler recommends that you read this section before you set the parameters on the
day/night tab.
IR Filter State
- Indicates the current state of the camera's IR-cut filter.
Night = The IR-cut filter is currently in the night position (filter is not in front of the sensor).

Day = The IR-cut filter is currently in the day position (filter is in front of the sensor).

IR Filter Switch Level
Level setting is mainly used to adjust when the camera will switch from day mode to night mode.
The higher the IR Filter Switch Level setting, the darker it must be before the camera will make the
switch. Setting the switch level to a higher value typically means that the camera will switch from
day mode to night mode later in the day, i.e., when it is darker.
If the current level of darkness (as indicated by the IR Filter Current Level parameter) rises above
the switch level setting and remains there longer than the IR Filter Wait Time (see below), the
camera will switch from day mode to night mode.
If the current level of darkness (as indicated by the IR Filter Current Level parameter) falls below
the switch level setting and remains there longer than the IR Filter Wait Time (see below), the
camera will switch from night mode to day mode.
IR Filter Current Level
auto IR filter control. As the area being viewed by the camera gets darker, the value of the IR Filter
Current Level will rise (a high positive value indicates that the area being viewed is very dark). As
the area being viewed by the camera becomes brighter, the value of the IR Filter Current Level will
fall (a large negative value indicates that the area being viewed is very bright).

IR Filter Mode
- Sets the mode of operation for the camera's IR-cut
filter.
Auto = The camera automatically senses the change from night to

day or from day to night and sets the position of the camera's IR-cut
filter accordingly.
Night = Move the IR-cut filter to the night position (filter is not in front

of the sensor) and keep it there.
Day = Move the IR-cut filter to the day position (filter is in front of the

sensor) and keep it there.
Input Controlled = The position of the IR-cut filter will be controlled by

the state of a camera I/O port.
For the input controlled mode to work correctly, the Direction
parameter must be set to "Input" on the I/O port you want to use to
control the filter position, and the Function parameter for that port must
be set to "IR Switch". See Section 3.9 on
about setting the camera's I/O port parameters.
- When the IR Filter Mode parameter is set to auto, the IR Filter Switch
