Advantages
1. F1.4 large aperture design, high luminous flux to capture sharp details for reliable traffic violation detection.
2. IR corrected optical design, unified focal position for day and night scenes, a core guarantee for stable traffic violation detection.
3. Controlled TV distortion at -1.52%, minimizing image deformation to accurately restore vehicle shapes and road features.
4. Optimized CRA at 10.5°, balances edge illumination and color consistency across the full sensor area.
5. Short minimum object distance of 0.5m, supports close-range road image capture for near-site detection.
6. Compact metal body with M40.5 filter thread, convenient for mounting IR-cut or polarizing filters.
7. Manual iris & manual focus structure, flexible fine-tuning to adapt to variable ambient lighting conditions.
Applications
1. Urban road intersections: Captures vehicle movements and red-light running behaviours for traffic violation detection.
2. Community access roads and city branch roads: Supports continuous 24-hour image collection under strong sunlight or infrared night lighting for traffic violation detection.
3. Tunnel entrance & exit sections: Adapts drastic light variation between inside and outside tunnels, delivering clear footage for traffic violation detection.
4. Urban viaduct ramps and roundabouts: Detects illegal lane changes and vehicle cut-ins, well-suited for complex traffic scenarios for traffic violation detection.
5. Urban traffic law enforcement points: Compensates for blind areas of long-focus cameras, providing authentic image evidence under mist and drizzle for traffic violation detection.
