Note:
detailed information about how the camera’s day/night functionality works. Basler
recommends that you read this chapter 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
- When the
IR Filter Mode
parameter is set to auto, the
IR Filter Switch
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
- Indicates the current level of darkness as measured by the camera’s 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
page 59
for
more information about setting the camera’s I/O port parameters.
