9.1 Alarm
Connecting an alarm input device with the camera can largely extend alert functions. For example,
when an infrared detector connected with the camera detects motion based on heat emission, an
alarm input message will be sent to the camera. On the other hand, by connecting with an alarm
output device such as siren, the camera will send signal to notify siren and thus make it activated
when receiving an alarm signal either from alarm input device or other detection settings. This page is
designed to establish related actions when the camera receives alarm input signal.
