Features 1.Effective Detection Capability: The blind spot detection system uses two probes installed on the rear bumper of your vehicle to analyze and process signals. This gives you a clear understanding of the distance, speed and movement direction of the vehicles behind you. 2.Advanced Algorithm: The system employs an advanced algorithm to identify fixed and distant objects. When a vehicle approaches within the blind spot, the indicator light flashes, helping you become aware of vehicles approaching from behind. 3.Active Collision Alert: If a driver continues to ignore the flashing signal and attempts to change lanes, the system will emit a BI BI BI alert, serving as an extra reminder of the potential danger and helping to prevent possible collisions. 4.Continuous Monitoring: Throughout the entire driving process, the system provides continuous detection and reminders. This feature will prevent potential traffic accidents due to adverse weather conditions, careless driving, blind spots in rear view mirrors, or inexperienced drivers. 5.Enhanced Safety: By providing reliable blind spot monitoring and alert warnings, this detection system significantly improves the safety of all road users, including you, your passengers, and other motorists. This is particularly crucial in heavy traffic, high speed roads, and multi lane highways.
