The infrared camera can see objects in the night because it is equipped with near-infrared light. Near infrared lamps generally emit near-infrared light with a peak wavelength of 850 nm. Infrared light is the same as visible light, and the illumination brightness decreases as the distance increases. To reduce the night vision noise within the visible range of the infrared camera, only from the increase of infrared light brightness, or increase the lens aperture, the use of high-quality filters and other aspects to solve. However, no matter from which point, it is impossible to fundamentally solve the problem of overexposure when infrared cameras are used to illuminate high-reflectivity objects (especially human faces) at close range (a few meters to a dozen meters). Because this is not a problem of uneven light uniformity, the brightness of close-range illumination has exceeded the CCD's sensitivity range or dynamic range. The electronic shutter adjustment of the camera by the CCD processor DSP alone has lost its function. Because ordinary electronic shutter does not have a smart detection function.
In order to solve these problems now include DSP manufacturers such as SONY, RJ, NEXTCHIP,etc., the new generation DSP has all introduced SMART IR intellectual infrared function. The fact that the infrared camera has existed for many years has been solved. The role of intelligent infrared is to automatically detect overexposure (only see a whitish object), automatically adjust the infrared camera brightness, so that the infrared camera can see the white part of the object. Faces are the most bleak and most important part of the monitoring process. Reality surveillance video found that many cameras monitor the distance, in order to reduce night vision noise, infrared lights are relatively bright. When a high-reflectivity object (such as a human) does not appear in the monitoring scene, the electronic shutter has an effect because it does not exceed the working range of the CCD camera, and the video image is better. However, when people appear and people are in close quarters, the face will appear whitish and no facial feature has been identified. This will lose the significance of monitoring.
Shenzhen Hanshi Electronic Technology Co., Ltd., with many years of user feedback, to solve the urgency of many users. Introduced a high-price ratio of low, medium and high 600 series CCD board machine, movement, module camera, series CCD board machines have intelligent infrared SMART IR function. It also includes a series of smart infrared cameras. So as to meet the choices of different users. Welcome new and old customers to consult or order.
