IR Waterproof Camera | IR waterproof camera principle how to deal with camera fog 
 Shenzhen Nanqiang Jin Rui Television Limited, is a professional security product development, production and sales of integrated high-tech enterprise. Since its inception on the spirit of "good faith to win customers, quality win survival, innovation win development" business philosophy, 
 The principle of the infrared waterproof camera 
 The basic principle is to use infrared waterproof camera to achieve night vision equipment ordinary light lotus CCD cameras feelings infrared spectral characteristics of the light source (that is, you can feel the visible light, infrared light can also feel) additional LED infrared lights as illumination source at night or shimmer environment imaging. 
 IR waterproof camera lens fog solution 
 The first case, the inside of the machine mist: fog, frost formation is due to the cold case of saturated water vapor in the air condensed due to the cold environment of strong, weak condense into frost and fog. Infrared camera in the course of their work, especially in indoor cameras often due to reasons such as fog or water vapor in the venue in the protective cover on the window glass formation of fog or frost, the camera can not see the object, directly affect the monitoring results. 
 The various methods of solving this problem is not the same. To increased defrost circuit, open vent holes, filled with nitrogen, plus fan, desiccant and so on. The method does not do it of course, are not the same, and some problems can be solved, some still can not solve the problem. However, from the most basic angle speaking, the strict control of the cleaning of the feed member, and it is necessary to eliminate the presence of a volatile matter as possible. For example, the PCB can not have residual flux, shading pouches made of high quality silicone material. 
 The second case, the outside of the machine frost, fog: 
 The camera work in the environment humidity shield the window glass is prone to dirt, causing the camera line of sight. 
 Solution: 1, increase in the protective cast wipers, by controlling the wipers clean glass. 2, the use of stealth wipers window glass. Stealth wiper window glass has to exclude the role of water, dust and ordinary window glass. 
 Finally, for the case of high humidity, some of the requirements for the sealing of the housing 
 IR Waterproof Camera application in the north, the body inside and outside will produce a large temperature difference, the front end of the lens will appear the phenomenon of atomization, thus requiring the machine must have a good seal, the shield should have a good anti-rain properties. 
 Stage, the mainland technology in sealing, there are some technical problems, such as the design of the shell, place the joints and screw interface, is leaking. 
 Tightness how to do better? Basic solutions: 
 Plus waterproof pouches at the interface plus water pad, play the role of water, the effect is more ideal. 
 In the terminal screws mouth playing waterproof glue, enhanced water resistance. 
 , IR waterproof camera with aluminum case to improve the accuracy of the interface, and the use of high quality silicone material stick together, the effect is more ideal.
