Feature 1Function: Car blind spot monitoring system is a vehicle assistance device that can greatly help you detect possible collision risks in your blind spot while driving. 2Principle: 4 radar probes are installed on the rear bumper of the car to detect speed signals. The system analyzes and processes the signals sent to understand the distance, speed and direction of movement of the vehicle behind. 3Flashing Reminder: Through the system algorithm, when a vehicle is detected approaching in the blind spot, the indicator light flashes. If the driver does not notice the indicator blinking and is ready to change lanes, the system will sound an alarm. 4Safe Protection: Continuous detection and alerting can prevent traffic accidents caused by potential hazards, such as bad weather, driver negligence, blind spots in mirrors, and novice drivers during driving. 5Performance: IP67 waterproof, operating voltage is 10.6V16V, reversing radar system detection distance of 0120cm/047.24in, and the best detection range within 0.5 meters, sensitive and accurate.Item Type:CarBlindSpotMonitoringSystemMaterial: PVC and metal .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }BSD System:1.
