Day/Night Functionality
Basler IP Camera 75
Controlling an External Device Based on the IR-Cut Filter Position
As mentioned on page 73 , the camera includes a capability called the IR-cut filter announce feature.
When this feature is enabled, the camera will "announce" the current position of the IR-cut filter by
setting the state of output pin 0. When the IR-cut filter is in the open position, output pin 0 will be
set to active. And when the IR-cut filter is in the closed position, output pin 0 will be set to inactive.
A common way to use this capability is to set the IR-cut filter to "auto" mode and to use output pin
0 to switch an IR illuminator on and off. Figure 9 shows a simple way that this can be done. In the
figure, the output is used to energize or de-energize a relay which in turn applies power to or
removes power from an IR illuminator. You could use a setup such as this to apply power to the
illuminator when the filter is in the open position at night and to remove power from the illuminator
when the filter is in the closed position during the day.
NOTICE
The text in this section and the illustration shown in Figure 9 are intended as a general description
of how you can use the output to control an external device. Any device that you attach to the
output of the camera must adhere to the specifications for the output as given in Table 3 on
page 66 . Using the output in a way that does not meet specifications can result in severe
damage to the camera.
1. Always make sure that any circuit attached to the output meets the output’s specifications.
