Infrared monitoring market favors low illumination

The development direction of video surveillance lies in the outdoor, and the development direction of outdoor surveillance lies in night vision, and the development direction of night vision lies in infrared technology. This trend is more and more obvious. In the field of infrared night vision, Chinese companies have taken the lead in the world, and some advanced technologies have made foreign counterparts far behind. So, what is the status of the infrared surveillance market? What will be the future development trend?

Infrared camera market development status Infrared camera manufacturers are in line with China's special market demand. It is understood that foreign markets basically do not produce infrared cameras. The reason for this is that the infrared camera itself is a high-temperature product and is a potential risk factor in most monitoring environments, such as coal mine monitoring, industrial monitoring and so on. The second is that the low-price competition of infrared cameras has seriously affected the product life. According to investigations, the average life of ordinary infrared cameras is generally less than one year. The short service life of the product may be more profitable for the infrared camera manufacturer, but it is for the end user to harm the interests of the consumer. The infrared camera market is irresistible, so each infrared camera manufacturers are constantly developing more cost-effective products. Foreign camera brands such as Samsung and Sony have also introduced infrared cameras to adapt to localization in China. However, in order to solve the drawbacks of infrared cameras, foreign countries have developed ultra-low illumination cameras. China can also develop more advantageous infrared camera products, make up for its own functional defects, it can also solve security risks.

At present, the infrared camera has the highest market share of LED infrared cameras, but the vast majority of products can only reach within 100 meters. In terms of applications, infrared cameras are mainly used in civilian applications. Infrared cameras have evolved over the years and the market is constantly updating. In the recent camera market, laser night vision cameras have emerged that can observe people and objects directly from the monitor during the night without using visible light.

Laser night vision camera technology is different from thermal infrared imaging technology and low light night vision technology. Thermal infrared imaging technology can only see the thermal profile of people and objects, and can not see the true face of the object. Low-light night vision technology requires a certain amount of moonlight, starlight, and ambient light to see the object. If there is no light, nothing can be seen. Although infrared light-assisted illumination can also see the target, it cannot overcome the infrared light storm, it can not be concealed observation, it is easy to self-exposure the target, the image is disturbed by light waves, and it can not reach the same visual effect and clarity as a black-sky night-vision camera. degree.

Since last year, infrared camera manufacturers have begun to introduce a night vision camera called white light, which is a product corresponding to infrared cameras. According to reports, the advantage of a white light camera is that it can display color images at night, unlike infrared cameras that can only take black and white images. White light night vision cameras have dimming technology. The intensity of light is determined by the perimeter environment. The darker the perimeter environment, the stronger the light. This kind of white light camera is more suitable for remote factories with few human traces, and its conspicuous light can also play a deterrent role. However, the actual effects of white light cameras and product quality still need to be tested in the market.

Infrared camera manufacturers also need a long process of development, infrared cameras have some advantages in some features, but infrared camera manufacturers can not sacrifice the life of the product for the price, how to solve the infrared camera short life, poor heat dissipation and other issues are also infrared cameras Manufacturers to solve the proposition in the future development of infrared cameras. It is hoped that China's security products will bring more practical functions to users on the premise of ensuring product quality.

Active Infrared Future and PIR Integration The current infrared camera market is quite confusing, mainly because the industry lacks a unified standard specification. For example, the irradiation distance of infrared lamps is often the highlight of various companies' propaganda, and they are not the same. The actual exposure distance is measured under what conditions. At that time, the ambient illumination is how the quality of the picture is presented. It is impossible to know how, but this is exactly the most serious test that infrared cameras face. Solving this problem has become the focus of common concern among companies.

Active infrared technology from the early efficiency of only 5%, to the current efficiency of 25-30% of the LEDArray technology, to meet the short-range infrared night vision technology breakthrough in the distance, and laser lighting technology is to achieve long-range night As one of the best ways to monitor, and light intensity is much stronger than conventional light sources, long-range night vision technology is a trend in the future night vision surveillance market.

The integration of active infrared technology and passive infrared technology will be one of the trends in the future. The use of passive infrared technology to find the target with strong penetrating power and long-distance radiation characteristics, and to use the principle of active infrared technology lighting to capture the target details can be The long-range monitoring provides strong "evidence."

In addition, integration with another type of night vision technology, micro-light technology, is also one of the future directions of development. In the period of continuous improvement of both low-light and infrared technologies, taking into account the complementarity between the two, without increasing the existing technical difficulty Based on the above, how to merge the low-light image with the infrared image to obtain a better observation effect, these two technologies have become the hot research of the current development of night vision technology.

Low-light cameras may become mainstream. ● Migration of image storage and video analysis capabilities to front-end equipment. Traceability in important applications is as important as image quality and stability. Companies represented by MOBTIX are increasing front-end image storage and video. Analysis to solve, this also represents the direction of future camera development to some extent. The benefits of doing so are on the one hand a traceable data source in the event of a sudden power outage or disconnection, and on the other hand (especially high-volume data such as high-definition) also slows down the transmission pressure on the network. Super-large monitoring applications are particularly important.

● The proportion of network cameras will be further increased. This article selected the current product lines of several major domestic manufacturing companies and analyzed them. In order to analyze more comprehensively and accurately, I selected more parameters, aiming at multiple parameters. Sampling can roughly see the current market trends and market share among different solutions. The market share of analog and network product lines (excluding ball cameras), the total number of sampling 305, simulation, 215, of which 29.5% of network product lines, analog accounted for 70.5%.

● Products using CMOS as a light-sensing device in network cameras will receive more attention, and the pace of network cameras in pursuit of higher pixels will increase.

● The demand for network ball and PTZ cameras will be reduced in the future. Instead, panoramic camera domes and PTZ cameras will once occupy an important position and a large market share in the Chinese security market, but domes and clouds Taiwan video cameras also have their own obvious defects: high cost, complicated installation and debugging; the failure points of traditional mechanical structures will also be more. With the development of panoramic cameras, high-definition lenses and optical sensing technologies, pure electronic solutions will be the mainstream of future development.
