FN 1.0 low Lux Night vision Lens
Camera designers will love it when they are going to make a night vision camera, 4.0 focal length means it’s especially suitable for monitors, the FOV are around100 degrees, also is fit for smart access control system, 1080P resolution enough for most of intelligent monitoring system or baby care monitor, some of the customers will put this lens on ADAS & DMS system for better night vision performance, it can also be used in robot system which be worked in low light environment.
