How to solve the fog problem of infrared waterproof camera ~!

The main reasons for this situation are the manufacturing process and quality problems of the equipment.

There are several reasons why water mist appears on the glass in front of the lens:

1. On rainy days, rain water seeps into the camera glass cover, evaporates in the glass cover, and forms water mist on the glass.

2. The sealing effect of the camera is not good, and the pressure inside and outside the glass cover is not equal, which leads to water infiltration and water mist after evaporation.

3. After the glass cover enters the water, the water will quickly evaporate into water vapor due to sunlight or temperature rise, forming water mist on the glass cover.

The way to prevent water mist is to start with the production process, replace the rubber pad with good waterproof property, adjust the pressure inside and outside the camera glass cover, and consult professionals for the rest.

In rainy days, if the general moisture-proof methods fail to achieve the expected results, individual moisture phenomena will occur. Special nursing should be carried out according to each "severe angle". Due to their own characteristics, different "hardest hit areas" have personalized dehumidification methods.

1. Wood floor

Disaster situation: the wooden floor is slippery, and there are obvious footprints when stepping on it. Black mildew was found at the junction of wooden floor and footstone.

Solution: The moisture on the ground is an important reason why the wooden floor is damp, moldy and even rotten. The laying of wooden floor is an important link to lay a good foundation for moisture prevention. After the wooden floor is laid, it is best to use it for a period of time, and then ask professionals to wax it. In this way, the residual moisture in the construction can be volatilized as much as possible, and the service life of the wood floor can be prolonged. In addition, Japan has also developed a kind of moisture-proof film specially for wood floors, which can be spread on the surface of wood floors to isolate the contact surface between wood floors and air, so as to better maintain wood floors.

Daily moisture-proof method

In the early spring of Chengdu, the home will be full of lingering moisture. In the face of humid living environment, people at home should plan ahead. If you want to do a good job of moisture prevention, you must first understand the basic preventive methods:

1. It is necessary to close the window in time.

Director Wang of the Air Quality Testing Center suggested that when humid air strikes in spring, residents must remember to close the windows, especially those facing south and southeast, so as not to give any chance for the moisture eyeing outside the window to sneak in. The most important period of moistureproof is in the morning and evening of every day. The air humidity in these two periods is higher than that at noon. If the doors and windows are not closed in time, water vapor will seriously penetrate into every corner of the house. In addition, if you feel that closed doors and windows prevent indoor air from circulating, I suggest you open doors and windows more at noon and afternoon.

It's good to use air conditioning once in a while.

The most convenient way to prevent indoor humidity is to use a dehumidifier or turn on the air conditioner from time to time to extract the moisture from the air. Manager Li of Xinmeijia Decoration and Design Company introduced that dehumidifiers or air conditioners can be used to change the humid indoor air environment after decoration, and can also be used to prevent the indoor air from being too humid in spring, resulting in the humidity of the home, especially the wood products and wooden floors. Changing the indoor air environment with air conditioning is a good way to prevent moisture at home now. Air conditioning is not only used to adjust the indoor temperature, which is warm in winter and cool in summer, but also can be used as a "dryer" to prevent clothes and furniture from getting damp and moldy in the wet season of spring.

3. It is very important to place desiccant skillfully.

According to the technical staff of the indoor environment testing center, there are many desiccants dedicated to moisture-proof and dehumidification in the market at present, and if they are placed reasonably, they can also achieve good moisture-proof effect. There are two most common types: moisture absorption box and dehumidification bag. Generally, the absorption box has various scents, and it is suitable to be placed between the corner of the sofa and the living room, under the bed in the bedroom and under the cupboard in the kitchen. The dehumidifying bag made of absorbent resin and charcoal is more suitable to be placed in narrow spaces, such as closets such as wardrobes and shoe cabinets, and a bag of dehumidifying bag can be hung to discharge moisture. In addition, you can put some mothballs in the wardrobe and shoe cabinet.
