Basic Connections

•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.

C Zoom/Focus adjustment terminal (ZOOM/FOCUS)

Zoom and focus adjustment operations can be performed remotely by external voltage control.
