Analysis Of Infrared Technology And The Security Of The Bond

[CPS Zhong'an network reporter: Wang Huaan] current infrared technology basically

divided into two categories, passive infrared, and the other is active infrared. It is actually a passive infrared signal itself does not give any, it is differences in the passive sense of the surrounding objects, so at night, the fog which, as long as the objects of temperature can be distinguished. Use passive infrared technology to produce the most representative of security products is a passive infrared camera and infrared detectors. And active infrared, is the machine take the initiative to issue an infrared light, infrared light than the human eye, but cameras that can sense the light. Currently, active infrared technology in the security of the more general use, infrared night vision cameras(cheap spy cameras) as regular, active infrared intrusion detector. In particular, uniform infrared night vision cameras night vision infrared LED light to do, inexpensive, greatly contributed to the popularity of infrared night vision cameras and development.

Infrared night vision camera:

Safe city with the gradual deepening of the more stringent safety requirements, more and more places need 24 hours of continuous monitoring. Infrared night surveillance applications in the more prominent, not only the treasury, oil depots, arsenals, cultural departments, prisons and other important departments, but also in the general monitoring system is also widely used, and even residential area monitoring project has also applied infrared night as cameras, infrared night vision camera so as to drive the market continues to heat up.

Or a similar scene at night in order to adapt the application, infrared night vision cameras(cheap spy cameras) are widely recognized. It combines video, infrared and other technologies, the configuration of the components of a camera, lens, infrared light, the three infrared night vision camera in the entire shoulder different responsibilities. It implements the basic principle is to use night vision equipment, optical coupling CCD camera feelings of ordinary spectral characteristics of infrared light (that you can experience the visible light, infrared light can feel), to attach the LED infrared light as a or low-light imaging environment. The power and angle of the infrared light, optical coupling CCD camera configuration, the choice of day and night switching filters, and whether there is a good deal of power to determine the IR thermal camera performance of the important parameters.

It is understood that, compared to the infrared camera, infrared night vision camera(cheap spy cameras) technology, the threshold is not high, most of the domestic market currently occupied by domestic brands, foreign brands accounted for only part of the high-end market . Infrared night vision cameras from domestic distribution, most Shenzhen, accounting for 70%. Infrared night vision camera because of price, features the absolute advantage, at present, infrared night vision camera sales have been the traditional bolt catch as many private security companies in China's main export. The camera module to install LED infrared light the way, is sweeping the entire security video surveillance industry has become fundamental to achieving all-weather monitoring.

However, due to infrared night vision cameras are achieved with LED infrared night vision, so subject to the development of LED. The LED also has some shortcomings: for example, if you want to achieve long-range infrared illumination LED will need more particles, so that both energy consumption and makes the camera too large, is not conducive to covert surveillance. In addition, LED lamp life is short, after a period of time will be less and less clear, thus affecting the picture quality.

Therefore, to improve the performance of LED lights to reduce energy consumption, improve image quality and radiation distance, infrared night vision cameras(cheap spy cameras) will be the future development and innovation lies. Prices have not a problem, as long as product performance can be further improved, I believe, infrared night vision cameras will be more.
