With the development of our country's economic construction, the security of the perimeter is increasingly attracting attention. The emergence of electronic fences has completely changed people's understanding of the concept of security protection.
China's perimeter security alarm system products are relatively late to start and are not widely used. Many places are only railings and wire fences. Although infrared detection products are installed in some places, they have high false alarm rates, high maintenance costs, and use of effects. Less obvious, and even some people jokingly called "infrared shooting, in name only."
With the development of our country's economic construction, the perimeter security work is increasingly attracting attention, especially important facilities related to the national economy and people's livelihood, such as airports, substations, telecommunications base stations, production wells, water stations, and military facilities. This requires a product that can really play a role in safety protection and safety. Beijing Zhongan Yutai Technology Company is committed to professional electronic fences to provide professional security services for everyone. Extended reading:. . Com
Electronic fences have been developed and used in foreign countries for more than 70 years and have undergone several changes. Nowadays, comprehensive use of computer, video, alarm, linkage and other high-tech means to make the product more mature, prevention effect is very obvious, is the world's latest type of perimeter security protection equipment.
In recent years, Beijing, Shanghai, Guangzhou, Shenzhen, Jiangsu, and other places have all started to introduce electronic fences, which have gradually been recognized by a large number of users and have been widely promoted. Our country currently uses more than tens of thousands of users.
The emergence of electronic fences has completely changed people's understanding of the concept of safety protection work. The original security measures mainly depended on the duty personnel on duty, infrared monitoring and so on. Belongs to civil defense. The rate of false positives is high, maintenance costs are high, and many human factors are involved, and the protective effect is not obvious. After the case occurred, they reported the case and arrested. The incident has already occurred. It has caused economic losses, caused social impact, and it is difficult to solve the case.
The new security concept of electronic fences is mainly based on blocking and supplemented by alarms. With blocking, alarming and monitoring as a whole, the system gives instantaneous lightning to the intruder. Has a strong deterrent effect. Prevent the occurrence of incidents, reduce the workload after the incident, and reduce the social crime rate. Electronic fences can be used in conjunction with lights, bells, and cameras. Remote monitoring. Can form intelligence.
At present, in China's perimeter security market, active infrared emission is introduced earlier, and the technology is relatively mature and most familiar and widely used. In addition, we can also see that microwaves and leaky cables can be used in certain applications.
With the development of science and technology, and increasingly stringent requirements for prevention, traditional perimeter alarm systems such as active infrared detection are difficult to cope with illegal intruders who commit crimes more wisely, or because of their own characteristics and limitations. Life and property security left some hidden dangers.
Active infrared radiation:
(1) The active infrared detection has a high false alarm and is affected by the external environment such as trees, pets, and rain. Frequent false alarms often cause paralysis or annoyance to the guards.
(2) The requirements for the installation environment are high, and the construction is complex and time-consuming.
(3) Maintenance costs are also relatively high.
electric fence:
Recently, the pulse electronic barrier perimeter alarm system that has gradually emerged in the domestic market in China has begun to recognize and accept more people because of its own advantages and characteristics:
(1) "Preemptive + reblock +
Post-alarm" triple protection. The pulsed high voltage power grid first gave a powerful shock to the attempted intruders, making them discouraged.
B. The intruder was given a pulsed electric shock to force him to leave; a fence composed of several wires effectively prevented man-over.
C. For those who forcibly cut or short circuit wires attempted to intruder, the system host immediately generates an alarm signal and can activate the device such as monitoring and linkage, and notify the on-duty personnel to immediately handle the police situation and take preventive measures.
(2) The false alarm is low and is basically not affected by the environment and pets.
(3) The installation is simple, and the requirements on the installation environment and conditions are not high.
(4) Maintenance and maintenance are simple and convenient, basically no need to invest maintenance fees.
