2.3.2 Installing Sensor & Alarm (optional)
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 detectors, smoke detectors and
infrared detectors. Once the DVR detects that the electric level meets the
user's settings it will trigger the DVR recording or alarm out.
For example, a sensor is connected to alarm input1 as Fig 2.1. Cable A
and B will be connected once the sensor detects an event. Users set
Device type as NC (Normal Close), refer to Fig 2.1. It will input +5V (high
level) to input1 when triggered, DVR will start recording.
