12mm F2.0 M12 Telephoto Lens 28.6 Deg DFOV 4G+IR Ultra Low Distortion for

OKS-G1220-M12 is a high-performance 12mm telephoto M12 lens specially optimized for low-power battery/solar security cameras, IoT surveillance cameras and long-range monitoring systems. Adopting premium 4G all-glass + IR optical design, it matches 1/3" CMOS sensor to deliver crisp high-definition details. The 12mm long focal length provides 28.6° diagonal narrow-angle field of view, ideal for long-range fixed-point monitoring such as corridor, road, fence line, driveway and entrance, capturing clear distant details while reducing unnecessary wide-angle data streaming and encoding load to save battery power. F2.0 large aperture greatly improves low-light sensitivity, realizing clear color imaging at dusk and night without extra infrared fill light, effectively extending battery life for low-power camera operation. Ultra-low TV distortion -2.0% delivers near-zero distortion natural 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 21.80mm TTL and Ø14.0mm front barrel design fits most low-power camera housings. Wide operating temperature from -40℃ to +85℃ with focus range 0.6m to infinity guarantees steady all-weather outdoor performance for battery security camera, solar WiFi camera and remote area IoT surveillance modules for mass OEM production.
