We all know that when the camera takes longer time to fit, there will be a mist. What causes it? Don't worry, let's explain how the waterproof webcam is dissipating.
Waterproofing network camera
A waterproof network camera is used to make a 58 lamp together to make a lamp board. The heat of its lamp is transmitted through the positive and negative levels, and it can not play a role of heat dissipation. Its packaging material is epoxy resin, the cracking layer will appear for a period of time, and then the phenomenon of light failure is presented, after 3 months, the transmission of infrared prevention The water network camera can attenuate 30. Next, I will explain how the waterproof webcam is dissipating.
The composition of fog and frost is due to the condensation of water vapor in the air, which is condensed into frost and fog due to the strong and weak cold environment. During the operation of the infrared camera, especially in the indoor camera, fog or frost can often be formed on the window glass of the shield because of the fog or water vapor, which causes the camera to be unable to see the object and directly affect the monitoring function.
There are different ways of dealing with this problem. Add defrosting circuit, register air hole, fill nitrogen, add fan, put desiccant and so on. Different ways of doing things are different. Some can handle problems, others are still unable to deal with them. However, from the most basic point of view, it is necessary to strictly control the cleaning of materials and eliminate the volatiles as far as possible. For example, PCB plates should not have residual flux, and the light shield should be made of high quality silicone materials.
The new generation of infrared waterproofing cameras have made innovations and improvements in the light in order to change the poor heat of the infrared waterproof network camera.
The new generation of infrared waterproof camera is a single lamp. One of its lights is equivalent to 70 to 80 of the traditional camera infrared light. Its lamp is through the lamp board (the lamp board is aluminum alloy) with a cooling block, through the chip to connect the shell, and then get the heat dissipation, its packaging material is the selection of selenium glue, Because there is no crack, there will be no light failure. Night vision is very good. Life can reach 5 to 10 years, and the naked eye can't see any attenuation in 2 years.
Therefore, the new generation of infrared waterproof webcam has good heat dissipation. If it is used, it will feel very hot on the shell, indicating that its heat energy is dispersed. Good cooling also prolongs the number of life.
The new generation of infrared waterproofing network camera is integrated with many points. Each lattice lamp can be integrated with 60-80 LED luminescent crystals. The volume of the integrated product is not too large, as long as the size of the nail covers. Because dot matrix lamps are highly integrated LED, they are much smaller than others.
Small volume is the most convenient application. If dozens of single LED combination infrared light source device is installed on the high-speed ball machine, the role can be imagined. The general product's luminous view is generally 7 degree -10 degree angle, thus forming a flashlight like beam, our luminous body's viewing point can reach 180 degrees. The room can illuminate the whole space evenly in the room. The optical output of a single LED is 5mw-15mw, while the optical output of a dot lamp reaches 800mw-1000mw, and the volume has only a penny size. This indicates that dot matrix lamps are clearer, brighter and more remote monitoring screens than similar products on the market.
There are two possible reasons: first, it may be due to the ambiguity of water vapor on the lens. On the other hand, the Sensor of the product is not very good, with the aging of a long time, the quality of the painting appears ambiguous, and may be the product is not very good sealing, there is water and gas mask on the lens. Two, the machine's own technological problems, the quality of the network camera will be simple to show the lens money fog, rubber washer out of oil, picture white, snowflakes, high noise and so on, this is due to the sealing of the skin ring aging.
