1
Alarm input or Day/Night switching terminals (ALARM IN1/2)
These input terminals can be used for either of the following purposes:
Alarm input
Connecting an external switch, infrared sensor, or other device to these terminals enables the camera to
detect alarm conditions such as the entry of an intruder.
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.
2
Alarm output terminals (ALARM OUT1/2)
Connect a buzzer, lamp, or other alarm device to these terminals.
