The ITR‑3811 is a state-of-the-art 4D MIMO traffic radar for highway, arterial, and intersection applications. As the cost-effective counterpart to the ITR‑3810, it‘s designed for smaller intersections and applications requiring reduced range while delivering the same high technical performance. Its multilane capability monitors, counts, and classifies vehicles across various road conditions worldwide. A single sensor covers up to eight lanes in one direction, with maximum detection range of 276 meters and precise classification of four vehicle categories up to 150 meters. Certified for global use, the ITR‑3811 offers reliable, efficient traffic monitoring and management.
