China - The Security Systems from www.securitysystemscctv.com has been widely welcomed by world famous hotel, restaurant and other public areas. Although their products are very excellent and good, there are also some inhibitions for their products.

The engineer from securitysystemscctv.com has said that the modern security monitoring equipment such as Security Systems all belong to the microelectronics products, which these monitoring devices have features of high density, high speed, low voltage and low power consumption. Because of the precision feature of the security monitoring system which is one kind of electronic device, their capability of resistance to over-voltage is very low. This device is very sensitive to lightning over-voltage, system over-voltage, electrostatic discharge, electromagnetic radiation and other electromagnetic interference, which making the monitoring system vulnerable to lightning over-voltage. This could result in paralysis of the entire monitoring system of the security system.

There are three situations which could directly influence the operating system of the security system.

The first situation should be the direct lightning which direct hit the outdoor Analog CCTV Cameras . This kind of situation could direct cause into damage to equipment. If the lighting direct hit on the cable, it would cause into the cable fuse and damage.

The second factor should be the lightning wave. If the power wire, signal transmission lines or metal lines of the security system was struck by lightning wave. If the lighting wave enters into these metal lines, it could lead to high potential difference which could lead to the equipment damage of the security system.

The third point should be the lightning inducing which could be divided into the electromagnetic induction and Electrostatic induction.

The first point should be the electromagnetic induction. When there is lightning occurring nearby the area of the Wireless Wifi IP Cameras, the land around the lightning strikes area will produce the strong transient electromagnetic fields. The monitoring equipment and transmission lines into the electromagnetic field will sense a greater force, which will cause into damage to the related equipment.

The second point should be the Electrostatic induction. When the charged thundercloud appears on the top of the security system or other electronic components, all transmission lines of these will induce with the opposite charge compared with the thundercloud. Once Thundercloud discharges, the bound charge will be rapid spread which will cause into lightning sensors. The lighting phenomenon which caused by the electromagnetic induction and electrostatic induction is known as the secondary lighting phenomenon. The probability of occurrence of this phenomenon is very largely. According to statistics, the induction lightning accidents accounted for over 80 percent of lightning accidents.
