Filters for optical fog surveillance cameras

The optical fog-penetrating surveillance camera, as its name implies, can penetrate a certain concentration of haze and dust to achieve accurate focusing. This is the basis of optical fog-penetration. The quality of the lens determines the effect of optical fog penetration. The professional optical fog penetration surveillance camera lens has a built-in filter with a strong target. The function is to accurately intercept the light of the required band. In order to adapt to specific environmental conditions, it often loads more The film is aimed at filters of different bands and is linked with the camera through the 485 interface to achieve switching. Normally, a camera with a fog-permeable lens only needs to have a day-to-night conversion function in terms of basic imaging performance. However, considering the high cost of the fog-permeable lens, some camera manufacturers have also begun to seek a more economical optical fog mode. Kanguang Optoelectronics Technology (Shenzhen) Co., Ltd. was the first to use a four-filter wavelength switching device. Its chief technology officer Jiang Wenlai introduced: "Different from the day and night conversion cameras with two filters in the past, we have innovatively added four filters to the camera. In addition to realizing day and night conversion, it also achieves strong light suppression by adding a filter that can selectively filter light in the 400nm-600nm band; of course, in order to more accurately intercept the near-infrared band suitable for imaging, a special fog filter is also added , In order to achieve a more economical optical fog penetration. This mechanical device can be automatically controlled by the camera or can be manually switched. The four-color filter photoelectric combined intelligent fog penetration camera integrates the two functions of optical fog penetration and electric fog penetration. , Can achieve fog penetration more than twice the visibility."
