The Smart Crosswalk Alert Beacon with Laser Grid Projection is an intelligent warning system designed for non-signalized pedestrian crossings, particularly at night when traffic lights are inactive or switched to yellow flashing mode. By deploying smart alert devices at both ends of a crosswalk, the system projects red laser beams onto pedestrians' lower legs as they approach, forming a distinct red light band. This enables motorists to detect pedestrians from over 100 meters away, even under conditions of poor lighting, driver inattention, or visual obstructions (e.g., glare from opposing vehicle headlights, rain, or fog). The system prompts timely driver reactions while simultaneously alerting distracted pedestrians (e.g., "phone zombies") to enhance street-crossing safety. It effectively mitigates traffic incidents by addressing key challenges such as insufficient stopping distance at high speeds, low visibility in adverse weather, and pedestrian inattentiveness.

Product Functions
The system employs laser radar detectors to identify pedestrians and instantly projects red laser beams to create a visible light band, ensuring early warnings for both drivers and pedestrians. It supports synchronized operation across multiple devices within a group and integrates with a cloud-based platform for remote management, including real-time monitoring, command customization, and parameter adjustments (e.g., brightness, operational schedules). The voice module offers flexible alert configurations with multiple built-in options, while safety mechanisms—such as automatic laser deactivation during unauthorized access, collisions, or close pedestrian proximity—ensure user protection and system integrity. Designed to perform reliably in diverse weather, road, and lighting conditions, it significantly improves pedestrian detection and collision avoidance.
Product Highlights
Enhances safety at night and in low-visibility environments by providing clear, long-range visual cues to drivers, reducing accident risks.
Solves critical issues like inadequate stopping distance at high speeds and poor pedestrian discernment in adverse weather (e.g., rain, snow, fog), where the laser beam effect becomes more pronounced.
Effectively alerts distracted pedestrians through red light projections and auditory signals, addressing the "phone zombie" phenomenon.
Boosts driver awareness with a detection range exceeding 100 meters, ensuring timely responses even in challenging scenarios such as glare or low illumination.
Incorporates robust construction, intelligent safety features, and cloud-based controllability for seamless adaptation to various intersections, ensuring durability and compliance with industrial standards.
