Vehicle Anti‑Intrusion Structure Solution
The ultrasonic vehicle intrusion prevention solution is based on the ranging principle of ultrasonic radar. The sensors continuously emit ultrasonic pulses and receive echoes to monitor real‑time changes in obstacles around the vehicle (or inside the cabin). When an object (e.g., a hand or foreign matter) approaches doors, windows, or enters the vehicle’s alert zone, the system detects intrusion via sudden changes in echo time, amplitude, or other features, and immediately triggers an audible/visual alarm or sends a notification to the owner. This solution offers high sensitivity, fast response, and immunity to lighting conditions, making it suitable for parking surveillance, window‑break detection, in‑cabin life presence monitoring, and more.

Intrusion detection

Open type ultrasonic sensor

ROA system uses open type ultrasonic sensor. The product is installed on the top of vehicle, and detects moving objects with ultrasonic range detection principle.

Sound alarm

Buzzer

When the open type sensor detects the moving object at the vehicle rear seats, the alarm will be turned on to remind the driver.
