Cell phone jammer will do no damage to cell phones

Natural light and artificial light sources each have their unique chromatographic composition, which may be beneficial for a camera, it may be against them. Most black and white system, lighting, image quality depends only on the total light energy, or energy received by the camera, and can not distinguish the different fiber colors. If the light right on the spectral curve of the sensor sensitive area, the illumination light can be the most efficient use. Color CCTV systems the situation is more complicated.   cell phone jammer     has a complete frequency covering range and optional shielding range. For can sense all of these colors in the visible spectrum of light. In order to achieve better color balance, light source and the sensor's spectral sensitivity curve must match. Most color cameras have automatic white balance control, which can be adjusted automatically by electronic circuitry to achieve the right color balance effect. Must include all the visible light in color, so as to respect these colors on the monitor. The sun, tungsten, halogen, xenon lamps and other broadband light source can produce very good color images, because they contain all the colors of the spectrum of frequencies. cell phone jammer will do no damage to cell phones.Mercury arc lamps and sodium vapor lamps and other narrowband light source spectrum is not continuous, so color reproduction is poor. Mercury emitted red light is very small, so the mercury arc lamp, a red object will become black. Similarly, given a large number of high-pressure sodium yellow light, orange light and red light, blue or blue-green objects in this light will become black, gray and brown. Low-pressure sodium lamp produces only yellow light, it is not for color CCTV system.
The drawback is the large consumption of the law, you must use direct current, operating current large-Eleven, infrared light to make the intake level of a clear image, contrast appropriate, must ensure that the best illumination of the camera , illumination in the environment can not meet the requirements, you need to configure the camera auxiliary lighting to achieve the requirements of the nominal value of the video signal 1Vp-p, the standard value of 0.7Vp-p, the illumination of the video signal when the value of 1 / 3 to 1 / 2 standard plant, so when the camera in the most low-light image, and never will, "as the same day."The dealer or customer can master how to install    cell phone jammer at site with the instruction of installation training document. In addition, most low-light camera generated when the image clarity is the use of test cards for testing television signal type, and its black and white stripes, black reflectivity requirements of nearly 0%, white reflectivity greater than 89.9%, while we observe in the field sometimes do not have such conditions, such as: leaves and grass is very low reflectivity, contrast is very small , it is unlikely to obtain a clear image, so the actual use of them can not be the most low-light cameras as a measure of the nominal field of environmental illumination standards an ordinary television monitor lighting system depends on the type of light source used in the specific time of observation, in particular, yes yes and outdoor applications. cell phone jammer can be installed on various places according to the installation specification requirements, including the wall, ceiling and so on.  During the day, working conditions will change with the weather conditions (sunny, cloudy, rainy, etc.) change, because the weather changes cause changes in the composition of the outdoor light spectrum. a lot of auxiliary lighting, commercial lighting can be used equipment can be, at night, the most commonly used incandescent, halogen lamps, sodium lamps, mercury lamps and high intensity discharge metal arc lights.
