Configuring the Camera
Basler IP Camera 17
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 Wait Time
- Sets the amount of time in seconds that the value of the
IR Filter Current
Level must remain above the IR Filter Switch Level setting before the camera will switch from day
mode to night mode. It also sets the amount of time in seconds that the value of the
IR Filter
Current Level must remain below the IR Filter Switch Level setting before the camera will switch
from night mode to day mode.
A feature called the IR filter announce mode can be set to use the camera’s digital
output pin to "announce" the current state (open or closed) of the IR-cut filter. For
more information, see Section 3.8.1 on
page 45 and see page 73 .
