3.2.1.3 I/O Device
To use [I/O Detect] mode, you should set the [I/O Device]. Please refer to the video demonstration in the
upper left corner of this dialog box. It shows how 2 infrared sensors trigger the recognition. 2 infrared sensors
can prevent most of the trigger generated by people walk through. You can also adjust the distance of the 2
infrared to prevent bicycle or motorbike. Normally, it is at least 1.5 meter apart. Magnetic Loop Detector is the
main sensor device to be used for I/O trigger. For Magnetic Loop Detector, 1 input is enough to trigger the
system.
