PRE-ALARM
Set recording period in seconds just before perceiving sensor input up to 3 seconds of time
length.
The system records in certain seconds of time prior to the time that alarm is activated, so that
user can search video even before alarm is triggered. The pre-alarm recording mode is always
“continuous” at the recording speed that user sets in “record” of “camera” menu.
TYPE
Select the sensor type between N/O(Normal Open) and N/C(Normal Close), connecting to alarm
input plate. Circuit of N/O type is usually open, and the activation of the sensor occurs at the time
of close, and N/C type works the reverse way.
NOTIFY
User can select how to be alerted upon sensor is activated or motion is triggered by pressing
“NOTIFY” button.
The system will generate buzzer sound in the selection of buzzer and/or make pop-up screen of
the camera in the selection of camera pop-up.
Note
Check the setting of the sensor type (N/O or N/C). It is recommended to use “Dry
Contact Type” while “Wet Contact Type” may cause the damage to the system.
The alarm might not function if the used sensor type and the system setting are
inconsistent.
Note
“Camera pop-up” means that multi-screen live video mode will be switched to single
channel mode automatically upon alarm triggered. This single channel video is the
channel triggered by alarm.
3.2.4. Motion Alarm
Motion alarm is to start the recording when motion is detected by installed camera based on the
area setting. The system will trigger alarm signal via the selected sensor-out channel.
