As the first line of defense for safety in various places, the perimeter plays a vital role in people's production and life. In order to adapt to various perimeter security protection applications and meet the user’s requirements for a simple, stable and reliable perimeter alarm system, Alean has launched a laser beam-to-beam perimeter alarm solution, which has a farther detection distance and correctness in the application. The advantages of faster light, lower false alarms, and stronger environmental adaptability are very suitable in long-distance perimeter environments such as airports, prisons, campuses, military, substations, petroleum and petrochemicals, and railway platform crossing detection.
Through the Alean perimeter laser beam alarm system, it can effectively stop all kinds of illegal intrusions and avoid personal and property losses; it can realize the linkage of laser beam and video surveillance, police lights, and electronic maps to achieve civil defense and technology. The purpose of the combination of defense and defense is to enhance the perimeter security level.
1. System introduction
System composition:
This set of programs mainly includes equipment including Alean intelligent frequency conversion laser beam, alarm host, software platform, sound and light alarm, address module, etc.
Working principle:
According to the design requirements of the three-dimensional defense, Alean laser beam detectors are installed on the perimeter wall. According to the number of defense zones set by the on-site environment, each defense zone can be linked to the perimeter video monitoring system through the linkage device to carry out related alarm linkage.
When there is an intruder over the wall to block the laser beam at the front end, the laser beam will send out an alarm signal at this time, and the alarm signal will be uploaded to the alarm control host and the back-end platform, and the alarm area will be displayed on the LCD Chinese keyboard display, or through the alarm management software The electronic map display and the intelligent video monitoring system are linked together. The on-duty personnel can check the on-site situation in time. At the same time, the alarm system can also link the on-site sound and light alarm to remind the security personnel to pay attention, so as to respond quickly and stop the intrusion in time.

2. The intelligent alarm controller and alarm management platform support the functions of arming, disarming and receiving alarms for front-end equipment;
3. The monitoring center supports sound and light alarm prompts, as well as electronic map positioning, video linkage and WeChat alarm reception functions;
2. System advantages
Compared with the traditional perimeter alarm system, the perimeter alarm system based on Alean frequency conversion laser beam has greater advantages:
Faster to light;
Both the receiving and transmitting ends of the Alean laser beam are designed with small windows, and the 4-digit digital tube displays the intensity, which can quickly read the beam signal, indicate the working status, analyze the signal strength, and refer to the data for faster and more accurate light. In addition to the digital tube display, Alean is also equipped with a laser guide, which detects the laser beam through acousto-optic prompts during the alignment process, and then cooperates with the digital tube to display the signal intensity of the beam, so that the alignment can be quickly achieved. The humanized design can make the equipment enter the working state faster and improve the installation efficiency of the system.
Longer detection distance, lower false alarm rate;
Alean laser beam detection range is 0-500m, which is suitable for various places that require long-distance protection.
At the same time, the laser beam adopts intelligent frequency conversion technology and 8-segment frequency conversion is optional to avoid cross-light interference between beams and reduce false alarms to a lower level. It is suitable for various applications with complex environments and long-distance detection.
Better environmental adaptability;
Alean Laser uses intelligent frequency conversion technology for the beam to give each pair of beams the transmitting and receiving frequency to avoid cross-light interference between the beams and reduce false alarms to a lower level. The laser is more concentrated and has stronger penetrability, which can effectively suppress the harsh natural environment such as wind, frost, rain, snow, and fog, and has better stability. Support custom alarm trigger response time (100ms/200ms/300ms/700ms optional), and trigger alarm time can be set according to the on-site environment to avoid false alarms caused by vegetation, birds, etc.
Linked alarm, quicker response;
The system alarm can be linked with on-site video surveillance, electronic maps, sound and light alarms, etc., to ensure more accurate, timely and stable transmission of alarm information, and to guard the perimeter security around the clock.
Longer life and cost savings;
The front-end laser beam is selected from the original imported laser head of Class Ⅰ, the equipment has a longer life, which can increase the life of the entire system as a whole, and save more costs for users.
3. Introduction of Alean laser beam-to-beam products:
The Alean laser intrusion detector is an anti-intrusion alarm (hereinafter referred to as the alarm) developed based on laser technology. The alarm is divided into a transmitter and a receiver. The transmitter can send multiple beams to the receiver after being modulated. Laser. When there is no obstruction between the transmitter and receiver, the detector will not alarm. When someone intrudes illegally and the laser beam is blocked, an alarm will be triggered.
Features:
Intelligent frequency conversion design, 8-segment frequency conversion optional
It can be freely set to block one beam or multiple beam alarms
Invisible laser light source design, operation is more concealed and safer
The spacing of each beam is 15cm, which effectively reduces false alarms and false negatives, and different beam spacings can be customized
Freely switch between working mode and debugging mode, optimizing complex operations when facing light
Adopt wide voltage power supply, support AC/DC12~24V
Perimeter detection distance: 0~500m
