The higher sensitivity in combination with high definition sensor and larger aperture optics provides the best quality, most detailed&high-contrast, informative image in all weather conditions. Equipped with 12?m high-end thermal sensor and up to 640x512 pixel resolution offer an excellent temperature resolution to ensure the thermal image significantly sharp and richly contrasted. With a high-performance aspheric germanium lens, the super large aperture f/0.9 offers better temperature radiation capturing capability. Compared with the f/1.0 aperture, the capturing of temperature radiation level is increased by 19%. The larger the aperture is, the more infrared radiation can be captured, and the image will be much clearer.
