3.7mm F1.8 Large Aperture M12 Lens 100 Degree DFOV 6G+IR Low Distortion Low CRA

OKS-3081-A4-650 is a high-performance F1.8 large-aperture M12 wide-angle lens specially optimized for 5G solar low-power outdoor security cameras, battery-powered WiFi surveillance cameras and smart home outdoor monitoring systems.
Adopting premium 6G+IR all-glass optical design, it matches 1/2.8" CMOS sensor to deliver crisp high-definition details. The F1.8 super large aperture greatly improves low-light sensitivity, realizing clear color imaging at dusk and night without extra infrared fill light, effectively reducing power consumption and extending battery life for solar-powered camera operation. 3.7mm fixed focal length provides 100° diagonal field of view, covering outdoor perimeter, yard, driveway and parking area with moderate wide-angle coverage.
Ultra-low TV distortion -9.5% delivers natural undistorted image, improving AI human and vehicle detection accuracy for smart motion alert. CRA below 15° ensures uniform brightness from center to edge, reducing dark corners and outdoor sunlight glare. Compact 14.5mm TTL and Ø14.0mm front barrel design fits most compact solar camera housings perfectly. Wide operating temperature from -40℃ to +85℃ with focus range 0.6m to infinity guarantees steady all-weather outdoor performance for 5G solar low-power security camera, battery WiFi camera and smart outdoor surveillance modules for mass OEM production.
