Infrared technology has been widely used in the field of security monitoring in recent years due to its ability to achieve clear shooting of images in a zero-light environment at night. Infrared cameras need auxiliary light sources to complete monitoring work in night view or zero illumination environment. From the early high-power halogen lamps to the current led array infrared lamps, the infrared camera technology is developing and progressing to meet security monitoring. Market demand.
In the market, infrared cameras have also become popular in recent years. As early as 2003, domestic surveillance manufacturers have begun to explore infrared cameras. With the continuous development of technology and market, many domestic monitoring equipment manufacturers have introduced a large number of infrared cameras to the market in 2006. So far, according to statistics, the output of domestic infrared gun cameras accounts for about 50% of the total number of surveillance cameras. This shows that the market has great demand for infrared cameras.
According to Quan Quanwei, an expert from Shenzhen Wave Grain Technology Co., Ltd., the BL-5720I-PWL-II is a new 5 series infrared gun camera that has been launched into the market. It boasts a 1.3 megapixel COMS sensor, which is due to its clear and smooth quality. Realistic colors. In addition to all the advantages of the BL-5720Q, the BL-5720I-PWL-II adds an infrared lamp, IR dual filter switcher, and a photosensor to the front end of the BL-5720I-PWL-II. Due to its excellent low-light performance, it not only senses visible light. Strong, and infrared light is also strong, because of this, the machine compared to the market similar to millions of ordinary high-definition infrared machine can greatly save the number of infrared lights, extending the life of infrared lights, small power consumption and small heat.
With the ever-increasing social security monitoring requirements, the drawbacks of analog surveillance have become increasingly prominent. Under this circumstance, high-definition surveillance is leading the development trend of security surveillance with its clear and outstanding surveillance quality. Not only in the technical aspects of high-definition monitoring is the current trend of security monitoring in the mainstream and the future, in the market, the demand for high-definition monitoring is also increasing, from the government's safe city, to real-time monitoring of port traffic, from factory and mine management to chain stores Safe operation, more and more projects and contractors began to use high-definition digital surveillance. Most monitoring equipment manufacturers are also optimistic that in 2015, megapixel digital high-definition cameras will surpass the analog cameras and become the overlord in security surveillance.
