2.3.2 Install Sensor &Alarm
The DVR has 16 channel alarm input and 4-channel alarm output.
Alarm Input:
The alarm input is triggered by electric level (High: 5V, Low: 0V). Users can connect external sensors, like gas detector,
smoke detector and infrared detector. Once the DVR detects that the electric level meets the setting users make, it will
trigger DVR to record or alarm out.
For example, a sensor is connected to alarm input1. If the sensor gives relay out(switch on/off), user need set the sensor
according to the switch status at alarm. If the switch is open at alarm, users need set SENSOR TYPE as NC(Normal
Close),. Cable A and B will be disconnected once the sensor detect event. It will detect +5V (high level) to sensor1 when
events happen. DVR is triggered. it will record and output alarm.
