Array red exterior night vision surveillance technology revolution (1)

According to Maslow's theory, the demand is divided into physical needs, security requirements, social needs, to respect the needs and demands for five categories of self-realization, human security requirements in the second only to physiological needs.

Sustained economic growth and living standards of citizens, and thus the demand for safer, more and more respected, security market demand every year is fast growing trend. In particular, a series of international and domestic security incident, the entire security monitoring market demand has been further expansion.

In the security monitoring, video surveillance is a mainstream branch, in any event, the legal community must be based on facts, therefore, video monitoring is also the most widely applied.

In recent years, the video surveillance technology with a degree of development, however, in video surveillance field always has a prominent issue that has not been satisfactorily resolved, it is the night video surveillance. Night surveillance is critical, but surveillance cameras like the human eye, the light is too dark when unable to clearly see the goal that can only be understood broadly outlines, does not recognize, it cannot be used as "evidence" has probative force. To resolve this problem, the security industry to manufacturers of a lot of ways, for example, active infrared led IR, laser infrared, passive infrared thermal imager, light night vision, and so on technology. While we are most widely active infrared night vision technology is actively exposed and use target reflection infrared source of infrared to implement monitoring of night vision technology, in order to achieve the camera night monitoring requirements.

Current monitoring industry more than 95% are using this technology for night vision surveillance, LED infrared led by own infrared wavelength of light irradiation be monitored objects.

Infrared line is not in the visible range, therefore, generally are not visible. Infrared brightness determines the monitored objects of clarity.

Development of infrared technology

Active semiconductor infrared technology in the early 1960s by United States Bell Labs successfully, the earliest infrared conversion efficiency of only 5%, the efficiency is very low, most used in infrared remote control and other simple products.

After the night vision application repeatedly practice and development, through the individual IR led packaging, fixed on the lens, to surveillance camera from proactive as supplemental lighting. A single LED infrared diode effectively efficiency at 20%, but there are obvious defects, that is subject to heat treatment and luminous power significantly reduce that lighting distance shrinking, often less than the nominal of illumination; there is a product of the volume is limited by the number of LED pipe, in order to meet the lighting requirements, it is imperative to use multiple LED tube Assembly, causing the volume increases, the application is not easy. In addition, because the LED heat cannot be effectively disseminated, resulting in an overall increase in the temperature of the cavity, seriously affecting the performance of the CCD camera, which is why the market mainstream infrared camera life is short, use after a period of time, significant variation.

Based on the urgent needs of the market practice, the original array red exterior LED infrared technology, a revolutionary improvement came into being.

Array infrared night vision technology, essence or through emitting active infrared wave camera manner night vision effect, but with advanced packaging technology, and dozens of high power, high efficiency of infrared leadframe package on a flat surface. This technology the birth was unusually rapid development.

Array infrared cameras monitor the application of the maximum advantage of solved problems LED light source of the heat, with very high luminous efficiency and light intensity, photoelectric conversion efficiency than conventional infrared LED cameras improves the efficiency of 25% to 45%, and greatly reduces the energy consumption, increased lighting distance, while at the same time extend the service life of the camera, array infrared night vision camera useful life is generally normal infrared camera useful life of 9 times.

Array infrared camera's main advantages

High brightness

Obviously, the higher brightness, light irradiation distance is farther away, a single LED output light power is 5 ~ 15mW, although you can increase the current to improve brightness, but the materials themselves that limitation is, infrared photoelectric conversion efficiency is not high, only 20% of the light, the remaining 80% is the thermal energy.

Therefore, increase the brightness, but also produce more heat, the temperature requirements strict camera key device CCD, obviously will not work. In addition, multiple combinations is LED to the PCB as the carrier, the thermal performance is not good. While array infrared camera light, by dozens of high efficiency and high power of Crystal through high technology package on a flat surface, good heat conduction device configuration. At the same time increase the efficiency of its photoelectric conversion, luminosity is a single LED by 100 times.
