What is a color-turning black camera

Have you heard of anything that is a color-turning black camera? The color-turning black camera is also called a day/night conversion camera, which is a camera that can be used during the day and night. Because in engineering applications, we often find that black and white cameras have higher sensitivity than color cameras, and can get good images in darker environments, especially when used with infrared light source, it can achieve 0LUX, so we call it The color-turning black camera is a day and night camera.

Since the CCD of a color camera responds to light differently than the human eye, especially when it is affected by non-visible light during the day, it is filtered by a filter. However, in this case, the infrared rays in the application at night are also blocked. It is necessary to know that the CCD's response to infrared rays is quite good at night, just as the human eye responds better during the day (of course, there is no color). In order to solve this contradiction, developers want to provide images through the same camera during the day and night, and there are many ways to solve this problem.

For a long time, there have been different opinions on the day and night dual-use cameras. Some say that the day and night dual-use camera is not practical, the camera color turns black, can be used as a monitor that the user watches every day, but can't turn the color to black, and the color monitor can see where the black and white image is better; Said that for color CCD, the natural resolution is lower than the black and white CCD of the same grade, the same CCD, how to deal with it is not possible to achieve the effect of black and white; it is said that although the frame accumulation has improved some effects, but in At night, the noise is still very large, and the smearing of the moving object cannot be solved. It seems that it is the itching of the boots and the like in solving the problem of day and night. Here, there are complaints from engineers who use their imaginations to make a big difference. Some manufacturers or sellers have different interpretations of day and night cameras on their own, so that the engineering companies who need to purchase products are in a dilemma. "Pony crossing the river".

In the continuous expansion of the concept of day and night camera and the continuous innovation of related technologies, the product level is increasingly rich today. It is inevitable that the current situation is such a situation. As a purchaser, how to purchase a project that suits your own needs, and the price is good. The product is sometimes not easy. Aidax believes that first of all, we must match the technical personnel with the day and night camera, fully understand the user's requirements and the actual needs of the project environment, and fully understand the exact meaning of the indicators in the day and night camera. This work is difficult to use in the word "full", because the day and night camera is still changing and developing, new things will continue to appear, and you will be prone to problems if you are not "full". Also, choose a brand with a larger product and a good reputation for the service. Generally speaking, the products with large brands and the performance indicators on the product data are more credible, especially the system is more systematic. Even if a new series is introduced, there will be fewer "side effects"; a good service and a well-known seller will Objectively introduce the advantages and disadvantages of certain products, so that you can take less detours in the purchase. In addition, choose a few more sellers, and compare them repeatedly so that you can know what you know. In the end, you must see what is being seen, and you can make purchases after repeated tests.

Installation and commissioning of day and night cameras, compared with the installation of ordinary cameras, there are some special places for the installation of day and night machines, because of the effect of nighttime, some manufacturers use 1/2" CCD target surface. For this type of day and night machine, it is also necessary to install a lens of not less than 1/2 inch when installing the lens. On the one hand, the image will not produce a vignetting angle, on the other hand, fully respond to the manufacturer to increase the photosensitive area to enhance the night effect. The original intention of the design, we must not use a small size lens to create a pity waste. Now with the wide application of day and night, the impact of ordinary lenses on infrared light is gradually reflected, some manufacturers have developed infrared lenses to correct this effect Idas believes that this type of lens should be used as much as possible during installation.

In addition, the automatic aperture lens should be used as much as possible to make the effect of the day and night machine more fully displayed. Thanks to the technological development of DSP, the camera debugging is now more and more delicate and more accurate, and the debugging method can be more varied. Pure menu debugging, menu and DIP SW with debugging, remote debugging, pure DIP SW, etc., the camera with pure menu mode looks clean and neat, only a few buttons, even these buttons can be hidden, but in the field debugging Don't forget to bring a small monitor, otherwise you will be exhausted. Remote debugging is very convenient, but generally it must have the same brand of back-end control device support, and most of them are coaxial transmission with the video line, it can be regarded as a kind of coaxial video control. The DIP SW method is much simpler and is suitable for lower-end users. It is also necessary to pay attention to some manufacturers who do not know why. When adopting the menu and DIP SW cooperation mode, sometimes some functions will be repeated. The first time the second debugging will be confusing, don't be confused.

In recent years, there have been many related products in the security industry and surveillance cameras in the complicated "spinning period", and foreign products have also landed in the domestic market. How to choose a color-turning black camera? At present, it is also the biggest headache for engineering companies. Good product prices remain high. Other products do not achieve the expected results, and in the end can also face no profit. With its many years of production and promotion experience in core areas such as integrated wiring systems and closed circuit television, Aidax has become the world's leading professional video surveillance system manufacturer. Aidaxin will serve you with high quality products and services to create mutual benefits.
