Security Camera Lens

• High refractive-index (RI) optics deliver superior image quality

UN0391 features a 4 mm fixed-focus lens, F2.2 large aperture, and a 1/2.7' sensor, UN0391 features a 4 mm fixed-focus lens, an F2.2 large aperture, and a 1/2.7" sensor. Its day-and-night confocal technology ensures consistently clear imaging around the clock without requiring manual adjustment. With an 87.6° horizontal field of view, Ø6.9 mm image circle, high relative illumination (> 40%), and low distortion (≥–13%), it provides uniform brightness and true-to-life image quality. Compact and easy to integrate, the fixed focus lens is an ideal, cost-effective optical solution for HD surveillance and smart devices, ideally suited for large-scale project applications.
