Sanyo VDC-HD3100/HD3100P - Manual (Page 20)

If you are operating the camera for the first time, check the factory default alarm detection conditions on the
ALARM SETTINGS screen. Change the default settings as desired.
For details, refer to the “ALARM SETTINGS” section.
You can configure the camera to detect alarm conditions via the “alarm input terminals” or “built-in motion sensor”.
For how to configure the camera to detect alarm conditions via the alarm input terminals, refer to the “Alarm
Input/Output Terminal Connections” section.
Connecting an alarm switch, infrared sensor, or other external device to the ALARM IN1/2 terminal enables the
camera to detect alarm conditions such as entry of an intruder.
