The LPR radar Speed System is designed using the principle of radar speed measurement. It combines LED technology to display the speed of the vehicle in real-time to the driver. The device consists of three parts: 1) speed limit sign; 2) radar speed measuring device; 3) electronic display board. The electronic display board shows the speed of the vehicle and displays the speed of the fastest vehicle if there are multiple vehicles in the detection area.
The vehicle speed feedback sign is widely used in traffic speed measurement. It is a device equipped with a speed limit sign and an LED screen that displays the speed of passing vehicles in real-time. The LPR radar speed system displays the speed of the vehicle through radar speed measurement. The advanced speed feedback sign displays green for average speed and red for overspeed, which warns the driver to control their vehicle speed. The LPR system is equipped with a 220V mains power supply or can be powered by a solar panel and battery, making it efficient for remote speed-limited sections such as highways.
The speed feedback sign can be combined with a speeding camera that takes a photo of speeding vehicles. The camera sends the image back to the control center.

1. The NobTra radar system can use a mobile phone app to set parameters, making it simple, convenient and easy to operate. It supports Apple, Android and Hongmeng operating systems.
2. Adjusting the sensitivity is possible through the mobile phone app. It possesses ten levels of sensitivity, allowing the device to meet various project needs.
3. The brightness of the system is adjustable through the mobile phone app, with ten levels from darkest to brightest. This flexibility allows for adapting to different environments.
4. The NobTra system uses imported, high-brightness light-emitting diodes, which possess higher brightness and longer life. This provides good visibility during day and night.
5. The device is constructed from 2mm thick galvanized cold-rolled open-rolled board made of high-quality cold-rolled steel. It has overall baking paint on both the inside and outside and is resistant to impact, aging, corrosion, waterproof and dust-proof.
6. The NobTra radar system adopts professional traffic radar imported from Germany, with high-precision vehicle speed real-time display function, accurate and reliable speed measurement results, strong anti-interference ability, and high precision. It comes in built-in and external models.
7. The system possesses an all-day snapshot function, storing 20,000 speeding records. The mobile app can view snapshot records, and the camera will display the license plate number on the display.
8. The LPR camera has a maximum resolution of 2 million pixels, outputs real-time images, supports up to 256G SD cards and supports day and night use. The system perfectly recognizes many countries and regions, with a recognition rate of up to 99%.
9. The speed limit panel supports customization, with values such as 30, 40, 50, 60, etc. or other customized values.
10. Screen display control is independently developed by NobTra, allowing it to support multiple protocols and possess rich interfaces to meet customization needs. It comes in flexible working modes and multitasks, suitable for various application fields.
11. The NobTra radar speed limit sign is sealed and waterproof, making it adaptable to different weather conditions. The use of silicone three-proof paint effectively prevents moisture, salt spray, anti-static, and anti-mold on one side of the PCB circuit.
12. The display model supports custom warning characters and languages if the warning characters are short enough to be displayed.
