BY-J Toyota Sienna 2011-2020 Blind Spot Monitoring System, 77 GHz Millimeter Wave Radar 12V Universal Car Blind Spot Detection System, Sensitive Radar Sensors Blind Area Detection System

A driver assistance system for safer lane changes, this radar-based blind spot detection integrates LED indicators into the mirror glass to seamlessly match the Toyota Sienna's original design. It features a TI 2T4R 77GHz automotive-grade radar chip with ultra-wide bandwidth, detecting moving objects within a 3.5 m 70m range in both side and rear blind spots, far surpassing traditional radar. ^^ It operates stably at -40, providing all-weather detection in heavy rain, dense fog, and sandstorms; it remains sensitive at both high and low speeds, accurately identifying nearby vehicles; and it issues an alarm via LED indicator and buzzer if a moving object suddenly enters the detection range.

^^
