Anonymous users2024-02-07Perimeter alarm, real-time and effective detection and alarm for illegal intrusion, theft, sabotage and robbery in fortified areas. Perimeter alarm is a very important part of the weak current system of intelligent buildings.
The perimeter should be fully fortified, and there should be no blind spots and blind spots.
The detector has strong anti-interference ability.
The scientific division of defense zones is conducive to positioning.
The alarm center has various prompts such as voice sirens and alarm lights.
The alarm center can control the state recovery of the front-end device.
At night, it is linked to the perimeter searchlight.
Linked with TV monitoring system.
The alarm center automatically records and prints.

Anonymous users2024-02-06The 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.

Anonymous users2024-02-04Perimeter prevention refers to the prevention of the boundary of a specific area or when the boundary is invaded by outsiders after the alarm system and system, the use of intelligent phased array radar system, Internet of things intelligent perimeter vibration detection system and other advanced technology to form a visible or invisible "protective wall", if someone passes or wants to pass, the corresponding detector will send an alarm signal to the alarm control host of the security duty room or control center, and at the same time send out a sound and light alarm, display the alarm location.

Anonymous users2024-02-03Perimeter alarm is part of the safety precautions, there are a variety of equipment, such as electronic fences, the effect is good, is the construction is particularly difficult, I have consulted some companies to do this, Beijing companies are the majority, Jing'an can company is I 07 years of contact, do this equipment relatively early in the understanding!

Anonymous users2024-02-01Hello! Perimeter alarm system is a branch of burglar alarm in the security industry. With the increase in the importance of security, from the main installation in key places to the popularization of the city's neighborhoods, schools, factories, etc., in Jiangsu, Zhejiang and Shanghai and other mature areas, has been very common.
The perimeter alarm system is mainly divided into three structural layers: front-end detector (electronic fence front-end host alloy wire, vibration optical fiber sensing cable, etc.), terminal control layer (intelligent control terminal keyboard), and platform management (SAM200 alarm integrated management platform) to jointly create a strict security area.
The details can be queried independently, or to understand Shanghai Guangtuo, you can understand more professional content in detail and accurately.

Anonymous users2024-01-31I've only used infrared beams, I don't know anything else.
Over the years, the traditional perimeter security solutions (infrared radiation program, monitoring program, microwave radiation program, leakage cable program, vibration cable program, electronic fence, power grid, etc.) have made due contributions to social security, but limited by some objective technical conditions and other factors, there are still some commonalities or personality deficiencies, as follows: Infrared and other traditional programs, the level of protection is low, for the deliberate intruder, it is easy to cross or avoid; At the same time, they are susceptible to environmental restrictions such as high and low, twists, turns, and bends in terrain conditions, and they are not suitable for harsh climates, and are easily affected by natural climates such as high temperature, low temperature, strong light, dust, rain, snow, fog, frost, etc., and have a high false alarm rate; Leaking cable and vibration cable alarm belong to cable sensing, and the sensing part is active, and the system power consumption is very large; Electronic fences, power grids and other schemes are also harmful. The distance that can be monitored by the above scheme is short, and the unit distance cost is high, and the system cost is high under the condition that long-distance monitoring is required. >>>More
There are more and more application scenarios of talent assessment system, and many companies have begun to evaluate the personality characteristics and positions of employees through the talent assessment system, for example, as a project manager, I always want to select leaders from within the staff, but this is very difficult, then at the beginning of team building, it is necessary to understand the whole company up and down thoroughly, which is undoubtedly a big project, how to judge an employee, can have the opportunity to be promoted to leadership positions in the future, this is a problem, In addition, how do you ensure that the employee's overall values are consistent with the corporate culture? After being a project manager for so long, I deeply understand that in order to master all this, there must be a flexible information mining tool to help enterprises successfully complete team building tasks, so this is when the talent assessment system comes in handy. >>>More

The alarm amount on the electricity form is the current balance displayed by the smart meter, in addition to the SMS reminder when the power is about to run out, when the remaining amount in the meter is less than 100 yuan, the screen backlight will automatically light up, and the alarm red light will always be on, prompting to purchase electricity as soon as possible. >>>More
There are many kinds of patrol systems on the market, and whether you use them depends on whether the patrol system you choose meets your requirements. At present, the patrol system is divided into: stand-alone version and network version. >>>More
