Surveillance cameras all kinds of interference solutions appear grainy interference such interference, when not drown slight normal image, and the image can not be serious watch (even destroy synchronization). The reason for this failure phenomenon is also more complicated. Generally, there are several reasons: (1) The quality of the video transmission line is not good, especially poor shielding (shielded copper wire network quality is not very good, too thin, or not achieve shielding shielding effect). At the same time, this type of video cable line resistance is too large, resulting in a greater signal attenuation is also aggravated the fault. In addition, the characteristics of this type of video cable impedance is not one of the reasons beyond the specified parameters is 75 and failure. Due to the above-mentioned interference generated video cable is not necessarily bad and have a failure, so the reasons for this failure in the judgment to be accurate and careful. Only when the exclusion of other possible only after to consider the video cable from bad angles. Indeed, if the cable quality problems, the best way of course is to put all of this cable to replace all, and replaced to meet the requirements of the cable, which is the best way to solve problems. (2) Since the power supply system is not "clean" it caused. Power referred to here is not "clean", refers to the normal power supply is superimposed interference signal (50 weeks sine wave) on. This interfering signal on the power supply, this device uses the thyristor power grid came from. Especially in high current, high voltage thyristor devices, pollution of the grid is very serious, which led to the same power grid is not "clean." For example, this grid has power SCR FM control devices, thyristor rectifier, SCR AC-DC converter, etc., will cause pollution to the power supply. This solution is relatively simple, as long as the entire system is clean power or on-line UPS power supply to basically be resolved. There is a strong interference source nearby (3) system. This can be judged by the investigation and of understanding. If this is the reason, the solution is to strengthen the shield of the camera, and the video cable pipes in the ground processing.
