3.3 External I/O
The external I/O terminal can be used to connect an external input device (such as
a door sensor or motion sensor) and an external output device (such as a light).
By connecting an external sensor to the External I/O, the camera can buffer/
transfer images by alarm when there is a sensor detection (page 91). If the alarm
position has been registered (page 26), you can set the camera to aim the lens to
the alarm position when the alarm is triggered.
An external output device can be controlled by pressing the Output Control buttons
on the operation bar. The signal type sent to the device from the camera to the
external device can be set by clicking [External Output] on the Setup page
(page 106).
Explanation of the External I/O
Note
The External I/O (Input/Output) are independent. Output terminal is controlled
only by External Output Control page on page 106.
