With the development of the security industry, 24-hour uninterrupted surveillance has become increasingly demanding for night vision. Infrared technology has experienced development in different periods and has been widely used in the surveillance of night vision.
In the development of the night vision field, from the first generation of traditional LED infrared, array infrared, laser infrared, and infrared thermal imagers to the world’s third-generation infrared technology, the field of infrared night vision has experienced a field. The new revolution in infrared technology led the development of the night vision surveillance industry to a deeper and more distant direction, creating one bright spot for the security market.
Infrared technology was successfully developed by Bell Labs in the early 60s. So far, it has been widely used in the security monitoring industry. There are two ways to use infrared technology:
The first one is a passive infrared thermal imaging imager. It is generally used for special occasions, but the picture is only the outline of the object. It can not be used as proof of the presentation, and its price is extremely expensive, generally in the US dollar or even 100,000 yuan. As a result, no one has used this technology for monitoring systems.
The second type is night vision products that actively emit infrared light, which is currently used by more than 95% of the monitoring industry. Infrared monitoring systems illuminate objects by actively emitting light at infrared wavelengths (usually the wavelength range accepted by the naked eye is in the range of red, orange, yellow, green, cyan, blue, and violet, but not only red, but also violet, and the naked eye No, but the camera can capture, this is when the infrared light is turned on, we think it is still dark, but the fluorescent screen can see the truth), the brightness of infrared light determines the degree of seeing; at the same time because of different CCD The best sensing segment of the infrared wavelength is different, so if you use an inappropriate camera will cause the picture to be unclear.
Among them, active infrared technology is a commonly used technology at present, including laser infrared and IR-III technology that is about to be promoted globally. IR-III technology fills the first generation of traditional LED, the second generation of array-type fast light decay, short life, low electro-optical conversion efficiency, lack of brightness, poor thermal performance, power consumption and other shortcomings, is the global infrared night vision technology New breakthroughs, IR-III technology surpassed the first generation of traditional LED, the second-generation array type, leading the industry with unique technical advantages. Many industry professionals have stated that the company’s first IR-III technology will bring a huge impact to the infrared night vision field. The first generation of traditional LED, the second generation of arrays will face the crisis of class, laser infrared and IR- III Who will become the leader in the security market? Aroused the attention of more people in the industry. Below the characteristics of laser infrared and application to find out its difference with IR-III technology.
Laser Infrared Control Camera The biggest advantage of application in the field of night lighting is that the laser has high luminous efficiency, luminous intensity and directionality, and the electro-optical conversion efficiency of the semiconductor laser can reach up to 80%, greatly reducing energy consumption and increasing the illumination distance. .
Due to the use of a metal package and a dedicated power supply, infrared lasers can use advanced semiconductor temperature control technology to allow the product to always operate at a set and reasonable temperature, and its lifetime can be better guaranteed. Infrared laser lighting equipment combined with a camera with a long focal length lens can better achieve long-distance monitoring at night. Due to the complexity of the process and relatively low output, the price of infrared laser illuminators is still relatively high, and the market prospects are not optimistic. Many customers generally reflect higher prices. Due to the high price of laser infrared, long-range illumination lamps are particularly suitable for large-scale projects such as forest fire prevention projects and traffic projects, the civilian market cannot use laser infrared. There is also a certain side effect of laser on human health, so there is still some resistance in the market.
