Fisheye Lens with 184° Field of View, 3MP High-Definition, and F1.9 Large Aperture for Panoramic Monitoring

The F2.5-3MP-M12 (K104) is a high-definition ultra-wide-angle fisheye lens designed for 1/1.8" image sensors. Featuring an ultra-large 184° horizontal and diagonal field of view, this lens supports 3MP high-resolution imaging and delivers true panoramic monitoring coverage with fewer cameras.

Adopting a full glass 6G optical structure and F1.9 large aperture design, the lens provides high light utilization rate and clear imaging performance day and night. With compact mini size, stable industrial-grade working temperature and standard M12 mount, it is widely used in panoramic security monitoring, indoor wide-angle monitoring, and full-scene visual acquisition equipment. Custom processing service is available to meet personalized project demands.

• Ultra-Wide 184° Panoramic Viewing Angle: Horizontal and diagonal field of view reach 184°, vertical FOV 79°. It realizes super wide-angle full-scene monitoring, greatly reduces blind areas and lowers the number of required cameras for full-area coverage, improving monitoring efficiency and saving equipment cost.
• 3MP High-Definition Imaging Performance: Optimized for 1/1.8" large sensor, supporting 3-megapixel high-resolution image output. Restores rich image details with high definition, ensuring clear video footage for daily monitoring and image recording.
• F1.9 Large Aperture & Excellent Low-Light Performance: Equipped with F1.9 super large aperture, effectively increases light intake. It guarantees stable and bright imaging in low-light environments, suitable for day-night continuous monitoring scenarios.
• Full Glass 6G Premium Optical Structure: Adopts all-glass 6-group optical design without IR cut structure, with stable optical performance, low image distortion and good light transmittance. Effectively suppresses stray light and improves overall image clarity and restoration.
• Compact Mini Size & Easy Installation: Ultra-small lens dimension Φ15*18.86mm, lightweight and space-saving. Standard M12×P0.5 universal mount ensures fast assembly and strong compatibility with most surveillance cameras and industrial modules.
• Ultra-Wide Working Temperature & High Stability: Supports -20℃ to +60℃ long-term stable operation, adapting to complex indoor and semi-outdoor temperature changes. Suitable for 24/7 continuous working monitoring equipment.
• Flexible Focus & Wide Working Distance: Minimum focusing distance 0.2m, working distance ranges from 0.2m to infinity. It covers close-range detailed imaging and long-distance panoramic monitoring with strong scene adaptability.

• Indoor Panoramic Security Monitoring: Ideal for home security, office monitoring, shopping mall, supermarket and indoor public area full-scene panoramic monitoring. Ultra-wide angle eliminates monitoring blind spots and realizes one-camera full-room coverage.
• 360° Panoramic Visual Equipment: Suitable for panoramic camera devices, panoramic video conferencing equipment, full-scene image acquisition and visual perception systems, providing ultra-wide field-of-view image acquisition.
• Intelligent Visual Sensing Devices: Applied to intelligent equipment visual recognition, industrial wide-angle detection, access door monitoring and smart home visual acquisition modules.
