"Perimeter Power Grid" to understand ~
A grid composed of four metal wires can be seen on the peripheral wall around many communities. Multiple alarms are also erected on the grid. In addition, the warning sign "High voltage danger, no climbing" can be seen everywhere. Many owners will be very worried: "Is this high-voltage electricity? Just outside my balcony, it is dangerous." In fact, this power grid is not a generalized power grid, but a new type of anti-theft device, also known as electric fence.
The electronic fence integrates deterrence, blocking and intelligent alarm. Generally installed outdoors, along the original wall (such as brick wall, concrete wall and iron fence), the detector is connected to the near end, and the receiver is connected to the far end. If an intruder attempts to invade.
First of all, you will see the electronic fence hanging on the fence. It is forbidden to climb the warning sign, which gives people a psychological deterrence.
If you attempt to cross over and touch the metal wire of the fence, you will be given an electric shock to make it shrink away and dare not touch it again.
If it climbs forcibly, the system immediately calls the police. On the other hand, the electronic fence uses a flexible hanging pole. When the criminal attempts to cross, the flexible fence does not give support, so that the criminal cannot cross. This is the effective retarding function of the electronic fence.
In simple terms, the role of the pulse fence can be simplified into two parts: anti-theft and alarm. Because the structure of this kind of fence is composed of electronic cables with electric pulses, when someone attacks the electronic safety fence, the electronic cables can generate non-lethal pulse high voltage to effectively repel the intruder and play the role of anti-theft. At the same time, the system will also send the intrusion signal to the system management terminal to remind the security personnel to pay attention, so as to achieve the role of alarm. So it is a combination of anti-theft alarm.
Because the impulse fence has good anti-theft characteristics and strong ability to work autonomously, it can often be seen in the shadows of government agencies and civil security. In addition, because of its relatively strong ability to resist corrosion, it is also used in relatively harsh environments.
Such places as military bases, government agencies, judicial systems, key cultural relic sites, borders, private residences, real estate agents, industrial powerhouses, factories, warehouses, etc. can all be applied. Install on existing perimeter fences, walls, or free-standing. The system automatically adapts to changes in environmental and field conditions. Varies according to regional conditions. For example, in foggy and windy weather, the system can maintain the alarm value. It is easy to construct, does not need welding, and will not be threatened by erosion.
