I/O ALARM:eEach channel corresponds to an I/O status, which means when an alarm is
triggered, it will activate the corresponding channel to start alarm recording.
N.O.: Normally Open type. It means that in the normal state, the sensor device is kept under
constant low voltage. If output voltage changes from low to high, then the alarm is triggered.
N.C.: Normally Closed type (also – “normally connected”). The normal state of the sensor
device is under constant high voltage. If output voltage changes from high to low, then the
alarm is triggered.
OFF: set to “Off” if you are not going to use external sensor alarms.
OUTPUT: “ON” indicates that an alarm will go on if it had been triggered by sensor.
RECORD: “ON” indicates that the relevant channel will record if it had been triggered by
sensor.
BUZZER: “ON” indicates that the buzzer will turn on if it had been triggered by sensor.
PRERECORD: “ON” indicates that the relevant channel will pre-record 5 seconds if it had
been triggered by sensor.
EMAIL: “ON” indicates that the picture of relevant channel will be send to mail if it had been
triggered by sensor.
Note: If the output time, record, buzzer, prerecord and Email had been turned off, the relevant
option will not be triggered in any case.

to switch.
MD AREA: sometimes you need to have some regions
in your camera view with the enabled motion detection
feature, while other regions in the same view should be
free of this functionality. This may be handy when, for
example, the camera covers the road and an adjoining
territory. While you would like to have the motion
detection working on the area near the entrance to the
building, you most likely would not like to see it
triggered every time a car or truck passes on the nearby
road.
