Purpose and Functionality
Features of Noble 2 Digits Radar Speed Sign
Mobile App Control : Effortlessly set the speed sign parameters using a mobile app within a convenient 10-meter range. This app is seamlessly compatible with Apple, Android, and Hongmeng operating systems, ensuring broad accessibility.
Sensitivity Levels : Tailor your experience with ten distinct sensitivity levels. Level 1 offers the highest sensitivity, while level 10 provides the lowest, catering to diverse road conditions for optimal performance.
High-Quality LEDs : The speed sign utilizes premium imported materials, including high-brightness LEDs from Taiwan. These LEDs guarantee superior visibility, an extended lifespan, and vibrant colors, providing exceptional clarity both day and night. Adjust brightness across ten levels, from level 1 (darkest) to level 10 (brightest), to suit any environment.
Advanced Radar Technology : Equipped with imported, professional-grade traffic radar, this sign offers high-precision real-time vehicle display, accurate speed measurement, excellent anti-interference capabilities, and unrivaled accuracy.
Customizable Speed Limits : Customize the radar speed limit sign to meet specific speed requirements, such as 30, 40, 50, 60 km/h, and beyond, ensuring effective traffic control tailored to your needs.
Versatile Power Supply : This 2-digit, 2-color radar speed sign supports multiple power supply options, including solar, AC, and battery power. The efficient solar option guarantees 7-10 days of operation, even under continuous rainy conditions, ensuring uninterrupted performance.
Durable Design : The NobTra radar speed feedback sign features a robust sealed and waterproof design, engineered to withstand various adverse weather conditions, assuring long-lasting durability and reliability.
With the user-friendly phone app, effortlessly set parameters for the speed limit sign, such as brightness, power supply options (solar or AC power), and trigger speed. Additionally, access overspeed records via the app for enhanced traffic management convenience.
