Day/Night switching
Normally, switching the camera between the color and black-and-white video
modes is automatically accomplished by the Day/Night function.
Using one of these alarm input terminals as the Day/Night switching terminal,
however, enables the camera to be switched between the color and black-and-
white video modes when an external control signal is received.
To use the alarm input terminals as Day/Night switching terminals,
follow the steps below.
• Under [DAY/NIGHT], set [DAY/NIGHT] to “COLOR” and select the
terminal you want to use in [EXT ALARM].
• On the ALARM SETTINGS screen, in [POLARITY], select the signal
polarity of the alarm input terminal.

voltage control.
