Since the wide field of view lens has detection zones that are concentrated in a narrow band, there are less blind spots within the detection area. This allows for better accuracy of tangential movement detection over the standard lens. Not only do the detection areas increase in concentration, they actually overlap each other. This overlapping of detection zones makes detection possible even in scenarios where the movement is approaching the sensor directly. This "approach-sensing" detection is a unique selling point of this sensor that other suppliers do not have.
