recognition and then the recognition result will be output to open a gate, turn on a light and
etc.
In this application, the GV-I/O USB Box installed on GV-LPR is connected to the Door A
outputs on the GV-AS200 module. When the card is presented to Door A, the signal of
Wiegand A will be transmitted to the Door A outputs and it will trigger GV-LPR to activate the
license plate recognition.
