Car Radar Detectors are essential sensing components in smart parking systems, specializing in precise vehicle detection and trigger activation. By continuously transmitting and receiving radio waves, these devices accurately sense a vehicle’s presence, movement, direction, speed, and exact position. They provide real-time trigger signals to license plate recognition cameras, ensuring seamless image capture, while also enabling continuous parking space status monitoring. Designed for high reliability and consistent performance under various environmental conditions, Car Radar Detectors serve as a fundamental tool for achieving fully automated, all-weather vehicle management. Their robust operation significantly enhances system responsiveness, reduces missed detections, and supports efficient, data-driven parking operations.
