OKS-G1620-M12 is a high-performance 16mm super telephoto M12 lens specially optimized for wireless WiFi/4G CCTV security cameras, outdoor IP 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 16mm super long focal length provides 22.5° diagonal ultra-narrow-angle field of view, ideal for ultra-long-range fixed-point monitoring such as corridor, road, fence line, driveway, parking lot far end and building entrance, capturing clear distant details while reducing data streaming bandwidth for smooth wireless WiFi/4G transmission. F2.5 aperture provides stable imaging performance with good balance between low-light sensitivity and depth of field. Ultra-low TV distortion -2.0% delivers near-zero distortion natural image, improving AI human, vehicle and license plate detection accuracy for smart motion alert. CRA below 15° ensures uniform brightness from center to edge, reducing dark corners and outdoor sunlight glare. Compact 18.7mm TTL and Ø14.0mm front barrel design fits most wireless CCTV camera housings. Wide operating temperature from -40℃ to +85℃ with focus range 0.6m to infinity guarantees steady all-weather outdoor performance for wireless WiFi camera, 4G solar camera and remote area surveillance modules for mass OEM production.
