Why is the electronic fence more popular than infrared lasers?
China's perimeter security development is relatively late. So far, many places still use fences and other fences as protective measures. Now the electronic fences that are more prevalent in perimeter protection are also imported and processed by China. With the new perimeter protection equipment. And the development of the electronic fence has been updated several times so far, its performance is more perfect, can be linked with a variety of equipment such as computers, cameras, alarms, the prevention effect is very significant.
In recent years, Shanghai, Guangzhou, Shenzhen, Jiangsu, Zhejiang and other places have begun to introduce electronic fences, and gradually gained recognition from the majority of users, has been widely promoted.
At present, in the perimeter security market in China, infrared radiation is introduced earlier, and the technology is relatively mature and deeply familiar and widely used. In addition, we can also see the application of microwaves, leaky cables, etc. in some occasions. However, with the development of technology and more and more stringent precautions, traditional perimeter alarm systems such as infrared detection have not been able to meet people's security needs in many scenarios due to their own shortcomings and limitations. The three shortcomings of the biggest call:
First, the active infrared detection false positives are high, and are greatly affected by the external environment such as trees, pets, rainwater, etc. Frequent false positives often cause paralysis or boredom to the duty guards.
Second, the installation environment is relatively high, and the construction is complicated and time-consuming.
Third, the maintenance costs are also relatively high.
In response to these three shortcomings of infrared radiation, the electronic fence is very good in these three aspects!
First, the false positives are low and are basically unaffected by the environment and pets.
Second, the installation is simple, the installation environment and conditions are not high.
Third, the maintenance and maintenance is simple and convenient, basically no need to invest in maintenance costs.
The pulsed electronic fence in the electronic fence is slightly superior on this basis. It adopts the triple protection function of “first deterrent + reblock + post alarmâ€, and does not give every intruder the opportunity to commit crimes!
Shock : The pulsed high-voltage power grid first gave the intruder a powerful shock, which made it prohibitive.
Blocking : Give the pulser an electric shock to the intruder to make it leave; the fence composed of several wires effectively prevents artificial overstepping.
Alarm : For those who attempt to forcibly cut or short-circuit the wires, the system host immediately generates an alarm signal and can start monitoring and linkage devices to notify the duty personnel to immediately handle the alarm and prevent the problem.
Although infrared shooting seems to have no advantage compared to it, its shortcomings can also be its advantages. The reason why infrared radiation is easy to produce false alarms is because of its high sensitivity and wide range of protection areas, and infrared When shooting, the infrared beam is used, the human vision is invisible, and there is a hidden defense method, so that the intruder can touch the police without knowing it. Therefore, in the protection of some important cultural relics and confidential matters, infrared radiation is also the primary choice for prevention equipment.
Just because the electronic fence is more suitable for people with more traffic and noisy urban life, people naturally prefer the electronic fence in the choice. This is like “the industry has specializationâ€. Different perimeter devices have different The advantages are. All we can do is to maximize its "advantages" and reduce its "short board" to make it more accessible to people.
