About This

• Product Description:77GHz millimeter-wave BSD instantly enhances driving safety; Equipped with 4T4R automotive-grade radar chip, outperforms 24GHz in precision, range, and anti-interference. Two LED types are available: mirror-specific and general-purpose. It eliminates blind spots for driving, lane changing, and reversing, works reliably in rain/fog/snow, detects moving objects within 3.5×70m around vehicle sides, and alerts via LED and buzzer
