Day/Night Functionary
66 Basler IP Camera
Controlling an External Device Based on the IR-Cut Filter Position
As mentioned in Section 5.1 on page 63, the camera includes a feature called the IR-cut filter
announce mode. 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 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 58. 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.
