What are the perimeter alarm devices and what are the effects of use?

I have used the electronic fence, and the effect is good, but the construction is particularly difficult, and the vibration cable is also good.

Perimeter alarm is part of the security precaution, there are a variety of equipment, have consulted some companies to do this, Beijing company is the majority, Jing'an company is I 07 years of contact, do this equipment earlier.

I don't know, I haven't heard of it, I don't care.

I've only used infrared beams, I don't know anything else.

The perimeter alarm is generally composed of an alarm host, a front-end detector, an intermediate transmission part, etc. After installing the perimeter protection alarm system in the fixed area that needs to be protected, when someone tries to cross the boundary around the protected area, the detection device on the boundary detects the intrusion and sends out an intrusion alarm signal, and at the same time sends the intrusion signal to the alarm linkage part through the transmission part to prompt the relevant personnel to deal with it.

According to the different operating principles, the perimeter alarm products on the market are mainly divided into two types: pulse electronic fence alarm system and tension electronic fence alarm system

Pulse Electronic Fence System:It is composed of two parts: the pulse electronic fence host and the pulse electronic fence front end, the pulse electronic fence host emits a safe high-voltage pulse electricity, and is transmitted to the front end of the pulse electronic fence (alloy wire), and the pulse electronic fence host judges whether there is an intrusion by monitoring whether the pulse current is short circuit or open circuit. When there is an intrusion, the pulse host sends an intrusion alarm signal to the alarm linkage device and the control device at the same time.

Pulse electronic fence alarm system.

Tension Electronic Fence System:It is composed of tension electronic fence electronic parts Youchun and tension electronic fence front end mechanical parts. The tension electronic fence electronic component (detection module) determines whether it has been invaded by monitoring the change of the tension value of the mechanical part (tension line - uncharged) at the front end of the tension electronic fence.

When there is an intrusion, the electronic components of the tension electronic fence (tension controller) send an intrusion alarm signal to the alarm linkage device and the control device at the same time.

Tension electronic fence alarm system.

The difference between the two usage environments:The front end of the tension electronic fence is not electrified; It will not cause direct or indirect harm to the human body, and is widely used in schools, kindergartens and other places.

Lanxing perimeter security, their electronic fence is very intelligent is the perimeter anti-theft alarm system, which can be prevented in advance, the front-end fence with high-voltage pulse electricity gives the intruder a sense of deterrence, and the tangible perimeter fence brings more obstacles and real-time alarms to the intruder.

It depends on what type of product you want, whether it is domestic or imported.

Detector type: infrared radiation: generally ALEPH, but the infrared false alarm is high, the life is short, and the difference between which one is not too big.

Vibration cable: Beijing Security Police, they have a patent for vibration, and they did it relatively early; Beijing Jing'an can do more vibrating optical fibers.

Leaking cables: Shanghai Shenda, Beijing Security Police, Beijing Xinqinlin, etc.

Electronic fence: The electronic fence is the best in Shanghai, and the overall south is stronger than the north.

Laser radiation: This is currently a relatively small number of manufacturers, relatively large Shenzhen Daao, Beijing Security Police, Beiao Donghua, Changsha Xitian (Feitian).

Imported products are generally high, but they do have advantages in function, depending on the specific needs of the user.

ALEPH, Bosch, Fox, Honeywell can be.

Gies Perimeter: A professional brand of microwave cross-beam shooting.

Perimeter alarm is based on the needs of building security management, real-time and effective detection and alarm of illegal intrusion, theft, sabotage and robbery in the fortified area. Perimeter alarm is a very important part of the weak current system of intelligent buildings.

The purpose of the perimeter alarm is to establish a closed community, strengthen the management of entrances and exits, prevent accidental idle people from entering the community, and prevent illegal climbing over the fence or fence.

Requirements for the implementation of the function of perimeter alarm:

1) The perimeter should be fully fortified, and there should be no blind spots and dead ends.

2) The detector has strong anti-interference ability.

3) The scientific division of defense areas is conducive to positioning.

4) The alarm center has various prompts such as voice sirens, alarm lights, etc.

5) The alarm center can control the state recovery of the front-end equipment.

6) Linkage with perimeter searchlights at night.

7) Linkage with TV monitoring system.

8) Alarm center automatically records and prints.

Perimeter alarm equipment generally has infrared radiation, electronic fence, and now the latest has fiber optic vibration alarm. You see that some factories have iron mesh on the wall, then it is called perimeter, plus some alarm equipment, it is called perimeter alarm.

Systems such as electronic fence and infrared and laser beams are used in the field of perimeter defense.

To put it bluntly, the perimeter alarm is the security protection of a wall in your yard, and it is the outermost protection.

The meaning of perimeter in Chinese is the boundary of the periphery, and there is no need to explain the alarm, and the two are connected to the boundary of the periphery. In layman's terms, we install an intrusion alarm system on the perimeter of our fence or home. The current intrusion system is divided into three parts:

1. Front-end detection, such as infrared radiation, electronic fence, and passive infrared installed on the wall, all belong to it, which is similar to the human eye, and is the role of other observation and notification. Clause.

Second, the mid-end transmission is the mid-end alarm host, which is like the central nervous system of the human being, which plays the role of analysis and judgment to determine whether it is alarm information. Clause.

Third, the back-end management, is our software, the mid-end alarm host judges that it is the alarm information, through the transmission to the software, the software sends out the alarm, and at the same time indicates the address of the alarm site, so that the management personnel can rush to the scene of the incident as soon as possible! This is a complete set of perimeter alarm structure.

Hello! Perimeter alarm, as the name suggests, is a device system used in the perimeter to block the intrusion of people or animals, form an isolated area, and if there is an intrusion, it will alarm the device. It belongs to the security industry, and the perimeter intrusion alarm system category.

At present, based on the development of technology, perimeter alarm products in the market mainly include: electronic fence (the most widely used product), vibration optical fiber (suitable for places where electric fire is strictly prohibited, such as petroleum and petrochemical industry, perimeter long projects, such as airports, etc.), and leakage cable products and infrared radiation products leakage false alarm rate is too high, generally not recommended. The following is mainly recommended and introduced to the electronic fence.

1. What is an electronic fence?

Classification: tension type electronic fence (sensing the change of the tensile value of the front end alloy line).

Pulsed electronic fence (sensing changes in voltage value on the front-end alloy line).

Main components: front-end detection rods (installed on the solid wall of the perimeter of the community).

Fence host (installed on the inner side of the wall of the community).

Intelligent control terminal (installed in the security room of the community).

2. What is the function of electronic fence?

Eliminate external dangers: effectively prevent outsiders from climbing into the room to steal, injure people, and destroy facilities.

Strong active protection: It has the functions of "deterrence, blocking, and alarm" in one, and each alloy wire of the pulse electronic fence has a current, which is strongly blocked and has strong safety precautions. And high voltage and low current will not pose a danger to the human body.

Perceive all intrusion behaviors: Perceive various intrusion behaviors such as climbing, climbing, tensioning and compression, and cutting alloy wires, and there are no prevention loopholes.

No prevention blind spot: through the installation of electronic fences in the entire community, the combination of technical defense, physical defense, and civil air defense to form a closed independent area of the community, no prevention blind spots, more effectively ensure the safety of residents' lives and property, and eliminate the danger from the community.

3. What changes has the electronic fence brought to security?

More reliable: The leading technical defense means are more efficient and reliable than physical defense and civil air defense, and the data perception function.

Safer: Make up for the loopholes of civil air defense and physical defense, do not give intruders any opportunity, and guard the security of the community 24 hours a day.

Simpler: Through the intelligent control terminal keyboard, you can arm and disarm the area with one click, and all operations can be completed easily.

The electronic fence is a very important technical defense equipment in the current perimeter alarm system, which greatly improves the safety management efficiency of the property in the community, makes up for the security loopholes of the traditional physical defense and civil air defense, greatly improves the security ability of the community, and prevents the occurrence of theft and theft in the community. About specific products, recommended, Guangtuo electronic fence, T6 T8 touch net anti-bypass pulse electronic fence, belongs to the product of the current new detection technology, has been widely used in all walks of life, I hope to help you.

1 All 1Hardware Composition:

Front-end detector (generally infrared counter-beam detector) + front-end communication equipment (address code module) + front-end power supply (generally DC12V switching power supply) + central control host (alarm host) + management software + other auxiliary equipment (sound and light alarm, alarm linkage module, printer, etc.).

2.Basic Salary Principle:

The front-end detector detects the person and outputs the alarm signal to the front-end communication equipment The back-end communication equipment (generally installed in the control host) outputs the signal to the sound and light alarm of the control host, and displays the location, time and other information of the alarm on the alarm management software.
