 This phenomenon is mainly the effect of the flashlight or distance is not enough and so on. Actually, this is the main angle and function of the infrared light caused by the infrared camera used infrared lamps also known as 850 infrared emission control, the peak wavelength at 850, you can choose an angle from 5-60 degrees, when the infrared emission control angle more hours of irradiation distance farther the more obvious the effect of the flashlight, on the contrary, the larger the angle flashlight effect, but the distance is greatly reduced, to solve this problem is mainly to see the manufacturers want to pursue what effect and what the cost , of course, power and price of the infrared emission light is directly proportional to the number of lights, some manufacturers tell customers are generally? Distance can be achieved? However, we may have overlooked one problem - the power of infrared light and the diameter? In fact, power is no way to know when the look and size of the infrared light may be the only way the only physical test. Experience from my personal production of infrared cameras to solve this problem, I used a mixed installation of multi-angle infrared light
