Mechanical wear, misalignment, dust accumulation, or motor fatigue can cause flaps to jam halfway or move abnormally. BOV uses high‑quality gears and motors, precise alignment, and strict factory testing. Multiple IR anti‑pinch sensors plus auto‑reverse logic ensure the flaps stop or reverse when an obstacle is detected, reducing pinch risks.

Poor sensor placement or overly aggressive closing speed can cause the barrier to close on a person mid‑passage, especially in high‑traffic areas. BOV provides configurable opening/closing speed and force, and dense IR sensor coverage to detect children, luggage, and slow‑moving passengers. Emergency open on power loss and fire alarm input ensures the lane is always safe during evacuations.
