Infrared cameras are currently the highest market share of LED infrared cameras, but most products can only reach the illuminated area within 100 meters. In the application, infrared cameras are mainly used in civilian areas.Infrared camera after years of development, technology is constantly upgrading, recently appeared able to do the same during the day could be like visible light to directly observe people and objects in the night from the monitor laser night vision camera infrared camera on the market.Laser technology is different from the thermal infrared night vision cameras and night vision imaging technology , thermal infrared thermal imaging technology can only see the outline of people and objects , and see the true face of the object. Night vision technology requires a certain moonlight, starlight,and ambient light to see an object,if there is no light would not see anything . Although the use of infrared light auxiliary lighting can see the target,but infrared light can not overcome violence,not covert observation, the target is likely to expose the image by light interference , can not reach,like black light night vision video camera,like the visual effect and clarity . Since last year , the infrared camera manufacturers launched a product called white light night vision cameras,infrared cameras with a corresponding product . According to reports, the advantages of white light camera is also able to show in the evening color image,which is different from the infrared camera can only shoot black and white images. White light night vision cameras dimming technology, the strength of the light is determined by the perimeter of the environment , the darker the perimeter of the environment , the stronger the light. This white light camera more suitable for smaller remote deserted factory , and its visible light can also serve as a deterrent . But the practical effect of white light cameras and product quality also need to accept the market test . Infrared camera manufacturers take a very long development process , the infrared camera on some function has its advantages , but not at the expense of the infrared camera manufacturers at the expense of product life , how to solve the short life of infrared cameras,heat and poor is also an infrared camera manufacturers in the future development of an infrared camera to solve proposition. Because the domestic market demand for infrared cameras,infrared cameras fire also contributed to the large number of security companies to join. In the infrared camera market continues to mature,the infrared market has gradually formed a separatist dispute confusion pattern. Infrared cameras fierce market competition does not promote the development of the market , on the contrary , some of the original product issues have been resolved and often. Due to the low production threshold infrared camera , and a considerable part of the business specializing in the production and sale of camera accessories on the market , which provides for the development of handicraft workshop facilitated conditions, they pursue the ultimate goal is to maximize profits , obviously, quality becomes empty. Because of its low price for some regular manufacturers have impacted , making regular manufacturers market share gradually decreased. Forced by competitive pressures ,in order to hold the market, some manufacturers can only compress the regular cost . Pressure forced manufacturers , suppliers of raw materials for each material quality can only gradually " shrink" , resulting in overall product quality. Not previously appeared or have solved the quality problems began to rise , the market is heating up in the vicious price competition. From 2006 onwards , infrared cameras appeared very few new varieties , most manufacturers of the products is still the previous styles, different manufacturers of products without labeling, from the appearance is difficult to tell the difference between the two products. In fact , at this time , there are companies in their product line update , but a new product from R&D to the market after a very long time, but due to the fluctuations in the market price of the infrared camera is too easy to create a new product just a launch price will be subject to attack, and in a few years the development of new products , mostly single function, not particularly bright spot , leading to the promotion is also more difficult. Security industry has been a lagging industry standard since the early 1980s, China started in the security industry , so far , the domestic manufacturers still do not have a camera industry standard constraints.In this chaotic state , is almost impossible to measure a camera eligibility. On the other hand , national testing standards are inadequate mechanisms.The only domestic authority infrared camera quality testing is the Ministry of Public Security Alarm System Product Quality Supervision and Testing Center,and the center is based on the standard detection camera is "gb/t15865-1995 camcorder (pal / secam / ntsc) measurement method " for clarity only the detection of anti- voltage capability of conventional camera , brightness, signal to noise ratio and other parameters for testing, totally not related to the infrared camera and infrared light power,transmission range , night vision and other related indicators testing. But this does not play a threshold detection and strong constraints,which also contributed to an aspect of the infrared camera market more confusing.
