Infrared waterproof camera is a CCTV surveillance camera that integrates cameras, rain cover, infrared LED lights and other components. The basic principle of its realization of night vision is to use an ordinary camera equipped with an aperture CCD to sense the spectral characteristics of the infrared light source (that is, visible light can also feel infrared light), with the additional LED infrared light as an "illumination source" at night or micro Imaging under light conditions.
Infrared Waterproof Camera Fog Vapor Problems The fog and water vapor problems can be solved by the following ways.
In the first case, fog occurs inside the machine:
The formation of fog and frost is caused by the condensation of saturated steam in the air, which is condensed into frost and fog due to the strong and weak cold environment. During the working process of the infrared camera, especially the indoor camera often causes fog or frost on the protective window glass due to fog or water vapor. As a result, the camera cannot see the object directly, which directly affects the monitoring effect.
The solution to this problem is also different for each family. Increase the defrosting circuit, open vent holes, charge nitrogen, add fans, put desiccants and so on. The method is not the same, and the effect is certainly not the same. Some can solve the problem, and some still cannot solve the problem. However, from the most basic point of view, it is necessary to strictly control the cleaning of materials and try to prevent the presence of volatiles. For example, the PCB board cannot have residual flux, and the light-shielding rubber sleeve uses high-quality silicone materials.
In the second case, frost and fog appear outside the machine:
The camera works in a high-humidity environment, and the window glass of the protective cover is prone to dirt, causing camera vision to block.
Solution: 1. Increase the wiper on the protective cover and clean the glass by controlling the wiper. 2. Use invisible wiper window glass. Compared with ordinary window glass, the invisible wiper window glass has functions of repelling water, dust and the like.
Finally, for high humidity conditions, some requirements for the shell seal if the infrared waterproof camera is applied in the north, there will be a large temperature difference inside and outside the body, the front of the lens will appear atomization, so the machine must have a good The tightness of the protective cover must also have good rainwater resistance.
At this stage, there is a certain technical problem in the sealing technology of the mainland, such as the design of the housing, and in places such as joints and screw connections, where leakage occurs.
How to make the seal better? The basic solution is this:
First, add waterproof rubber sleeve, add water pad at the interface, play a role in waterproof, the effect is more ideal.
Second, in the connection screw mouth waterproof glue, enhance water resistance.
Third, infrared waterproof camera using aluminum alloy shell, improve the accuracy of the interface, and the use of high-quality silicone material, the effect is also more ideal.
