The development of perimeter security in our country started relatively late. Until now, many places still use fences and walls as protective measures. Nowadays, electronic fences, more popular in perimeter security, are imported from abroad and processed in our country. Only after transformation is current new type of perimeter defense technique available. In addition, electronic fence has been updated several times since its development, and its performance has become more perfect, it can be connected with computers, cameras, alarms and other equipment, and prevention effect is very significant.
In recent years, Shanghai, Guangzhou, Shenzhen, Jiangsu, Zhejiang and other places have begun to introduce electronic fences, which have gradually been recognized by majority of users and widely adopted.
At present, cross-infrared has been introduced to perimeter security market in our country before, and technology is relatively mature, so it is well known and widely used. In addition, in some cases, we can also see use of microwaves, leaky cables, etc. But with development of science and technology, and more and more stringent prevention requirements.
Due to their own shortcomings and limitations, traditional perimeter alarm systems such as infrared detection cannot meet people's security needs in many scenarios,
For example, three biggest disadvantages of infrared radio are:
1. Active infrared detection has a high false alarm rate and is highly dependent on external environment such as trees, pets, and rain. Frequent false alarms often cause numbness or boredom in staff on duty.
2. The requirements for installation environment are high, and design is complex and time-consuming. 3. The maintenance cost is also relatively high.
Given these three disadvantages of infrared radiation, electronic fence is very good in these three aspects!
Electronic fence benefits:
1. Low false positive rate, virtually independent of environment and pets.
2. The installation is simple, and requirements for environment and installation conditions are not high.
3. Repair and maintenance is simple and convenient, and there is practically no need to invest in maintenance fees.
The impulse electronic fence in electronic fence is even better on this basis. It adopts "first deterrence + blocking + alarm later" triple protection function, and does not give every intrusion an opportunity for criminal to commit a crime!
Deterrence: The SMPS primarily provides a powerful deterrent to intruders, making them deterrent.
Lockout: Shock determined intruders to convince them to leave; a multi-wire fence effectively prevents people from crossing.
Alarm: For intruders who forcibly cut or short wires, system host will immediately generate an alarm and start monitoring communication and other devices to notify duty staff to resolve alarm situation immediately and prevent problems, before they happen.
While infrared photography doesn't seem to have any advantages over it, its disadvantages can also be its advantages. The reason infrared imaging is prone to false alarms is because of its high sensitivity and large protection area. In addition, infrared rays are used in operation of infrared beam, which is invisible to human vision and has a hidden protection method, so that attacker will be activated without being aware of it. Therefore, when protecting some important cultural relics and confidential things, infrared radiation is also first choice of preventive equipment.
Just because electronic fences are more suitable for urban life with a lot of traffic and noise, people naturally prefer electronic fences in their choice. They have different benefits. All we can do is maximize its "benefits" and reduce its "short boards" to make it more human-friendly.
