The Fixed Vehicle Speeding Detection System (LDR-6 Evidence Eye Radar) comprises a fixed-angle radar, an industrial-grade high-resolution digital camera, a dedicated uninterrupted power supply for illumination, a wireless transmission module, and a backend data maintenance terminal. This system employs a self-developed narrow-band speed radar as the sensor, capable of measuring the speed of vehicles moving in both directions—whether approaching or departing—while stationary. It is designed for installation in roadside green spaces, operates effectively in various harsh weather conditions, and functions unattended around the clock.
