Most of the modern security monitoring system equipment is electronic equipment. Among them, this electronic device equipment is very sensitive to the effects of lightning overvoltage, electrostatic induction charging and discharging, and electromagnetic wave radiation, and it is very easy to be destroyed. In addition, nowadays, many people choose Internet traffic management and apply outdoor equipment lightning protection devices, and the damage from lightning strikes is becoming more and more significant. In the whole process of design and construction, it is necessary to reasonably improve the overall lightning protection level of the security monitoring system based on the characteristics of each security system software and specific relative lightning protection solutions.

For the lightning protection application in the whole process of intelligent security engineering construction, the key must be the safety protection of the power system software, the protection of outdoor equipment, and the system software grounding device.

First of all, for the safety protection of the power system software in the security, three levels of protection must be set. The first level protection SPD is installed in the main power distribution cabinet of the power supply; the second level lightning protection SPD is installed in the power distribution cabinet of the host room; the third level The protective SPD is installed at the power end of the equipment in the host room. Under normal circumstances, the first and second levels of the power system software have already been set up. If the third level protection is done in the whole process of construction, it is enough. According to the three-level protection of the power system software, it can resist the lightning current from entering the host room along the power cord in all directions to prevent the equipment from being struck by lightning.

Secondly, outdoor equipment must do a good job in the safety protection of shock thunder and magnetic induction thunder. Generally, the lightning safety protection of outdoor surveillance cameras is often encountered in construction sites. A small lightning protection ground must be installed on the support frame, and lightning protection devices should be installed on the power supply, control line, and video route of the surveillance camera. Or use a three-in-one lightning protection device to carry out all-round protection of the three data signals, and the ground wires of various lightning protection devices are connected to the lower ground on the network.

In the end, all system software will equipotentially connect and ground the working, protection, shielding, and building lightning protection grounding devices in accordance with the basic principles of voltage equalization and lightning protection and grounding to prevent the increase in ground potential difference caused by lightning strikes. The resulting overpressure.
