NBTR88-S30-S Digital Speed Limit Sign with 300m Visibility Range, 2.5-4m Installation Height, -40°C to 70°C Operation
The NBTR88-S30-S Digital Speed Limit Sign enhances driver safety awareness by preventing over-speeding and promoting slower speeds near curves. This radar-based system effectively notifies oncoming traffic to improve overall driving conditions.
Utilizing millimeter-wave radar technology, this speed sign emits electromagnetic waves to detect moving vehicles. When a vehicle is detected, signals are processed by the control board for speed calculation and display. Vehicles within the speed limit show green for compliance, while exceeding vehicles trigger red displays to alert drivers to slow down.

No. Radar speed limit signs primarily display vehicle speeds to remind drivers to control their speed. Speed cameras capture images of speeding vehicles for law enforcement and ticketing purposes.
They are typically installed where speeding is problematic, including arterial streets, school zones, construction sites, and residential areas. Installation must comply with local traffic regulations and safety requirements.
Recommended installation height is 2.4-4 meters above ground to avoid pedestrian obstruction and ensure clear driver visibility.
