Building upon features inherited from the VX-402 series, VX Infinity presents infinite possibility with the power of detection designs. VXI-ST demonstrates long & stable performance in typical outdoor environments. The VX Infinity Series is manufactured to excel in its performance whether as a perimeter detection solution, spot / area detection solution, or as an immediate perimeter/boundary solution directly on a structure (walls and rooftops). Digital Double Layer Detection: Both an upper and a lower detection areas must simultaneously be crossed to generate an alarm. The detections are independently analyzed so that a misleading coincidence of events can be filtered out. This technology virtually eliminates detections of smaller animals in the premises. SMDA logic (Super Multidimensional Analysis): All VXI models are equipped with a digitally enhanced signal recognition logic called SMDA. SMDA improves immunity against various noise factors such as climate changes and vegetation sways. VXIs expands applicable fields and reliability beyond what VX-402 was capable.
