Perimeter security electronic fence system, the full name is perimeter prevention pulse electronic fence system, referred to as electronic fence. Electronic fence has a strong blocking and deterrent effect, with a very low false alarm rate of the intelligent alarm system, with alarm interface, can be linked with the overall security system to improve the security level of the system.

01 Intelligent perimeter security pulse electronic fence concept:

"Deterrence is the main, the alarm as a supplement," deterrence and alarm dual function in one. Good security, low false alarm rate, strong deterrent, high reliability, wide range of adaptation.

Perimeter security electronic fence system main features:

1, with a complete, clear demarcation of the electronic fence, with a strong deterrent effect and deterrent effect.

2,Intelligent alarm system with very low false alarm rate.

3,With alarm interface, it can be linked with the overall security system to improve the security level of the system.

02 electronic fence system main components:

Perimeter security electronic fence system mainly consists of a set of pulse emission, alarm in one host, front-end, control, communication, linkage of five major components. Usually, the electronic fence in the outdoor, along the original fence wall (such as brick wall, concrete wall or iron fence) or floor mounted, the front end connected to the host.

03 Advantages of the electronic fence system:

1, for the perimeter system design, after the use of the pulse electronic fence statistics, you can cancel the dependence on infrared countermeasures and other equipment, reducing the owner's expenditure.

2, the perimeter security electronic fence system introduces the "blocking-based" intelligent prevention of new concepts in technology and functionality has made a fundamental breakthrough, easy to be accepted by users.

3, the system structure is reliable, long service life, the use of cost (the average annual cost and maintenance costs) has been reduced, which is favorable to the engineers and users.

4, perimeter security electronic fence system is easy to install and debug, can reduce construction costs, stable and reliable, long service life, low false alarm rate, basically no need for after-sales service, so greatly reduce costs.

04 electronic fence system blocking function:

Traditional infrared convection, leakage cable or microwave and other systems, only with the alarm function, but no blocking function. Intruders are often able to cross the alarm line unimpeded. That is, when someone intrudes, they may be within the security zone before the system generates an alarm. This complicates incident handling potentially.

The perimeter security electronic fence system erects a high-voltage electrified fence around the perimeter of the defense area. If someone attempts to invade, the first to see hanging on the fence "high-voltage danger" warning signs, giving a psychological sense of deterrence. If attempted to cross when touching the fence, they will be given electric shocks, so that they flinch away, and do not dare to touch again. If forced to climb, the system issues an alarm. Further, the perimeter security electronic fence uses a hanging wire rod with elasticity. When the intruder attempts to cross, the flexible fence does not give support force, so that the intruder can not cross. This is the effective blocking function of the electronic fence.

05 Are the electric pulses of the pulse electronic fence system a threat to personal safety?

While the pulse voltage of the perimeter security electronic fence system reaches 5000-10000V, the repetition frequency of the pulse is extremely low, only 1 time per second. The duration of the pulse is ≤0.1 seconds. The maximum energy of the pulse is 5 joules, and the maximum power of the pulse is 2.5 millicoulombs. It can be seen that its energy is so small that it will not hurt anyone, and it only gives the intruder a more difficult warning, shakes his ability and motivation to climb over the fence, and achieves the purpose of security blocking.

06 Pulse Electronic Fence System Alarm Function:

The traditional infrared butt-fire alarm system, as long as there are people or things passing through the cordon, the alarm will occur. Animals such as cats or dogs will alarm as usual when they pass by. Therefore, what shouldn't be alarmed is also alarmed. If there is inclement weather such as heavy rain or dense fog, the system fails and the alarm is again not sounded when it should be.

Perimeter security electronic fence system has a learning function, if someone is not careful and touch the fence, or other objects (such as tree branches) instantly touch the fence, because this is not a real invasion, the system has the ability to identify and not alarm. Only when the intruder forcibly invade, climb over the electronic fence, the system will issue the appropriate alarm, the current perimeter security electronic fence support touch the network, anti-shear, short-circuit, disconnection, tampering, malfunctioning, communication failure and other types of alarms, all-round guarding perimeter security.

07 electronic fence security:

While the voltage of the electronic fence is from 800V to 12,000V, which is a strong deterrent to intruders. However, whether the intruder can cause harm to the key to look at the current and pulse power of the, in general, the traditional prison with high-voltage power grid for a single pulse power of more than 40 millicoulombs, while the electronic fence of a single pulse power of only 2.5 millicoulombs, a difference of nearly 20 times.

Meanwhile, the pulse current of the electronic fence peaks at 300 milliamps in a one-second pulse cycle, with a duration of only 1.5 milliseconds, which is very short. And the current of the traditional high-voltage grid is more than 10 amperes. So as far as a single pulse is concerned, the energy of an electronic fence can merely achieve a sense of deterrence, not harm, and is safe. At the same time, if someone hangs on the electronic fence due to excessive tension, it will cause the electronic fence alarm, at this time, if the traditional power grid will stick to the intruder, causing a sustained blow to the intruder, while the electronic fence is every 1 second to send out a pulse voltage that lasts for 0.1 seconds, and when the alarm occurs, it will send out the alarm, which will give the intruder enough time to break free.

Meanwhile, the pulse host has two output modes, high voltage and low voltage, high voltage has a sense of electric shock, low voltage strikes a weaker sense, both modes can be alarmed. If you are worried about the high-voltage mode caused by the accidental injury, you can choose the low voltage mode, at this time is the safest.
