In the 1990s, the perimeter of the alarm product single, infrared radiation on its detection medium is not visible to the advantages of the market at that time into the mainstream intrusion detection of mainstream products. And look at the moment, electronic fence and other high-tech perimeter again and again, to prevent the transformation and upgrading of the coefficient to speed up the infrared radio is no longer meet the needs of today's society, the elimination will become an indisputable fate.
Infrared products on the market out of the market?
Inherently deficient
Infrared as the infrared radiation products, the most important detection medium, is a birth defects with a light source. The light source of energy is not concentrated, easy to spread, coupled with the rain, fog, light and other natural weather susceptible to weather interference weakened, the product is greatly affected by the operation. In addition, in the ideal environment, with the increase of the launch distance, the beam will also be anti-square attenuation with the launch distance, the use of such unstable infrared as a detection medium, even in the trigger time, alarm trigger conditions and other factors continue to improve , Are a temporary solution to the problem.
False negative rate is very high
Infrared on the use of high false false positives is the main reason for the user abandoned, because the product light source vulnerable to the external environment, including rain and snow, wind, light and other weather conditions; trees, birds and other animal disturbances will cause Infrared emission intensity immediately decay or beam offset, the receiver can not receive a complete beam, it will cause frequent false positives, so that security personnel miserable. In order to reduce the "false alarm rate", manufacturers will trigger the corresponding time to adjust to the maximum, or the shading time, reduce product sensitivity, no doubt the possibility of omission. In addition, because the product triggers the alarm condition must meet the completely blocked infrared shooting, leaving the intruder through the zone but does not trigger the alarm space is very large, in some weak security areas, the intruder close to the ground crawling, low profile across the form Can enter, such as the loopholes exposed its ability to adapt to the environment weak, high false alarm rate of deadly technical defects.

Install application limitations
Infrared radiation products to receive both ends to be fully received infrared, and therefore the installation environment is very harsh. Contrary to it, perimeter security products are gradually applied to all walks of life, involving a variety of complex installation environment, such as the bad weather environment, flammable and explosive oil depots, strong light of the southern region, green Planted dense area and many other occasions, infrared on the radio can not be installed and stable deployment, obviously can not adapt to a variety of installation environment. In addition, the installation of complex construction, power consumption, the latter part of the high operating costs, dead and other blind areas, etc., have become infrared can not be ignored on the issue. Undeniably, infrared shooting as the mainstream of the era of alarm products have long gone.
The rise of Internet of Things triggers new trends in perimeter detection
The continuous development of Internet of Things technology, to the Internet of things as the representative of the perimeter detector product iteration frequency, electronic fence, vibration fiber, leakage cable for the mainstream of the emerging perimeter detection products already meet the gradual upgrading of the market demand. In particular, the electronic fence based on "blocking the main deterrent, alarm supplement," no false alarm, applicability, performance and stability of the leading advantages of detection technology to solve the infrared system on the system defects, with its strong advantages, Become a new generation of social industry perimeter alarm system preferred intrusion alarm detection products.
Electronic fence vs infrared shooting
As a new type of perimeter to prevent alarm products, electronic fence set deterrence, blocking, alarm triple protection function in one. Relative to the infrared on the invaders without blocking, the pulse electronic fence front "physical" physical barrier strong blocking intruders, but also in the security range of active counterattack, delay the invasion time, and accurate positioning of the invasion, real-time advance Response to early warning, the first time to deal with illegal invasion, reduce the incidence rate. Currently on the market, to T6 / T8 series as the representative of the anti-bypass anti-bypass electronic fence, through the network transmission channel, perfect linkage video surveillance, access control, Patrol and other systems to create a more rigorous scientific security system.
The basic realization of intrusion detection 0 false negatives
Electronic fence front detection main material for the alloy line, with the basic installation of the weather from the inherent advantages of the environment, reducing the impact of false positive factors, significantly better than infrared products. China has the strength of independent research and development manufacturers, is constantly breaking the traditional technology vulnerabilities, some technical features lead the world. Take the T6 / T8 series of anti-bypass pulse electronic fence as an example, which uses Smart DEC intelligent algorithm (anti-equipotential crack technology), through the perception of the front fence metal line changes, through a series of precision operations, truly accurate identification Front fence situation, the complete realization of "touch", "anti-bypass", "short circuit" and "open circuit" four kinds of alarm, effectively resist a variety of intrusion, reduce omission. It is worth mentioning that, T6 / T8 series can also be calculated by the fence metal wire electromagnetic field changes in the amount of human touch or small animals and other natural interference, intelligent Internet of things sensing technology, basically ruled out the possibility of false positives Sex.

To adapt to a variety of high and low undulating terrain installation environment
As the front of the electronic fence is a visible fence, the installation can follow the terrain ups and downs of any laying, to solve the demanding requirements of the installation site, in the prevention area to form a blind spot, no dead ends, no loopholes in the security line, the system reliability is extremely high. In some special requirements of the place, such as in the petroleum and petrochemical industry, V7 tension electronic fence front end is not charged, wire grounding set does not emit electromagnetic wave advantage, to meet the petroleum and petrochemical industry fire and explosion security high demand. It is widely used in schools, factories, residential quarters, villas, substations, warehouses, military bases, airports, detention centers and other places to meet the needs of all walks of life per week.

The fundamental purpose of perimeter intrusion prevention is to use all kinds of advanced sensing technology to identify illegal intrusion, prevent and prevent the occurrence of malignant events, to solve the traditional air defense in time, geographical, personnel and other limitations. With the continuous expansion of security applications, the intrusion detection products, the reliability and false alarm rate requirements are getting higher and higher, Amotech electronic fence in technology and function compared to infrared on the radio breakthrough, its reliable and stable perimeter Detection performance, has become the mainstream of the field of the field of alarm trends!
