CHANNEL: Select the channel you need to setup.
I/O ALARM: Each 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 alarm type. In the normal state, the sensor device is kept at a constant low voltage (open circuit). If output
voltage changes from low to high, then the alarm is triggered (closed circuit).
N.C.: Normally closed type (also – “normally connected”). In the normal state, the sensor device is kept at a constant high voltage
closed circuit). If output voltage changes from high to low, then the alarm is triggered (open circuit).
OFF: Set to OFF if an external sensor alarms is not used.
OUTPUT: Set to ON if an alarm occurs when triggered by sensor.
RECORD: Set to ON for the channel to record when triggered by a sensor.
BUZZER: Set to ON for the buzzer to sound when an alarm is triggered by a sensor.
Prerecord: Set to ON for the channel to record the 5 seconds of video occurring before the alarm is triggered by a sensor.
Email: Set to ON for a snapshot of the channel video to be send by email after a alarm was triggered by a sensor.
NOTE
If the output time, record, buzzer, prerecord and Email is OFF, the relevant option will not be triggered.
