4.7. Alarm I/O Connection
Sensor input connection
Before connecting sensors, check the driving voltage and output signal type of the sensor.
Since the output signal type of the sensors are divided into a open collector and voltage
output types in general, the cabling must be done properly.
Also, the sensor type, i.e. "Normal Open" or "Normal Close" in the DIP switch of the main
body of the camera must be set properly.
