With the continuous development of the monitoring and security industry in Dongguan, the continuous expansion of the market, and continuous innovation of technology, users are increasingly demanding 24-hour monitoring. The infrared cameras we often refer to are also widely used. So, what are the classification of infrared cameras? Here's a brief introduction:
Infrared cameras can be classified into two types: CCD and CMOS; and they can be divided into traditional LED infrared lamps, second-generation array-type integrated light sources, third-generation array-type infrared light sources, and lasers.
Traditional LED infrared light <br> <br> it is currently the most widely used infrared light emitting device which occupies almost 95% of the market, but the quality is uneven, the price differences are large;
Its advantages are small size, simple production process, easy quality assurance, low heat generation, and reasonable luminescent optical system. It can be completely free of red storms (using 940-950nm wavelength) or only weak red storms (red storms have visible red light). , The service life of up to several thousand hours or more, is the ideal device to do infrared light, the current monitoring installation in Dongguan is widely used for night vision surveillance.
The disadvantage is poor heat treatment, resulting in too high ambient temperature affect the life of nearby electronic components (such as camera boards, control circuit board), light attenuation is too fast, generally less than a year will not see the night vision screen. Because it is encapsulated with "epoxy resin", "epoxy resin" will break when exposed to heat. After a long time, more and more fracture surfaces will be formed, and some light will be refracted when infrared rays pass through each fracture surface. This is the main reason why traditional LED lights have fast decay and short life.
Second-generation light source array integrated <br> <br> which integrates a number of pieces of infrared light emitting chip in a small range, and made a "thermal separation" process, such that the entire part can be placed in any size, any form of heat Physically, it solves the problem of heat dissipation and will no longer cause damage to other electronic components around it due to high temperatures. And because of the use of silica gel encapsulation, the material does not break and greatly reduce the light attenuation, and the lifetime is 5-10 times longer than the traditional LED lamp.
The disadvantage is that the price is much higher than traditional LED lights. Furthermore, in order to reduce the light transmission angle by using a lens to match the angle of the camera lens, many light points are inevitably deviated from the center of the lens, resulting in poor light transmission efficiency, as compared with conventional LED lamps of the same power. "Not bright enough" is its shortcoming.
Its photoelectric conversion efficiency is about 25%, which is 2.5 times higher than that of the first generation of ordinary infrared LED, and its power consumption is reduced by 2.5 times. The output of a single LEDArray is about 800mW-3.6W, and the brightness is about the conventional single LEDDE output. 5- 100m times of 15mW; LEDArray has an effective life of 10000h, which is more than 5 times longer than that of ordinary LED. It is made of metal, easy to maintain low temperature during operation, and has good heat dissipation performance; LEDArray half-power angle is 10°C-120°C. Generated (180 °C shape) of the light-emitting surface, to solve the ordinary LED indoor space can not be uniformly illuminated "flashlight effect"; LEDArray is a highly integrated chip, so the same brightness index under the volume is much smaller than other infrared products.
Laser lighting technology <br> <br> far as up to 3000 m, more than 20 times that of conventional products irradiation distance (120-150 meters). The laser has good directionality, the beam's angle is small, energy is concentrated, and there is still enough light intensity to spread far, so it is very suitable for long-distance lighting, used in large-scale environmental monitoring, forest fire prevention, scenic spot monitoring, and port terminals. Monitoring, oilfield monitoring and so on.
