Zhengzhou monitoring service to answer your infrared camera angle Cautions problems: First, the use of large viewing angles of infrared light with the overlooked angle lens, there is a waste of light followed, not the bigger launch angle infrared lamp, picture effect. the better. The amount of light the question: the relative aperture determines the ability of light through the lens relative aperture of f1.0 lens is the amount of light relative aperture f2.0 lens four times the same amount of light camera, infrared light monitor maintenance charges, respectively. With these two lenses monitor maintenance, infrared distance difference between the double role. large aperture lens infrared monitoring, better than the conventional four to ten times the normal lens, and normally should be monitored must be matched infrared night vision products. However, due to the high cost of technical difficulties, the vast majority of infrared products manufacturer does not have supply capacity. Color problem: all black and white cameras are infrared sensors, infrared light in the visible light color camera in terms of the conditions for a stray light monitoring maintenance standards, will reduce the color camera clarity and color reproduction, color camera filter. infrared rays is to stop participating in order to make the color camera imaging infrared sensors now have two practices, the first switching filter, blocking infrared entered under visible light conditions; in the absence of visible light filters remove elevator monitoring conditions Maintenance, let infrared enter such programs get better image quality, but the high cost and the switching mechanism causes a certain failure rate. Second, open a particular passage in the infrared filter, allowing light and infrared wavelengths the same infrared light come in, this approach does not increase costs, but slightly worse color reproduction.
