How to turn campus security off?

From the campus security incident, in recent years, the security scope of primary and secondary schools and kindergartens should not only be concentrated in schools, school gates, campus perimeter, school bus safety should be concerned, from outside to inside, such as from the school gate to the teaching area, from the surrounding walls The safety responsibility and construction safety guarantee system have achieved full video surveillance. The camera has been installed in all corners. Specialized personnel regularly check the screen of the LCD screen . School safety is generally concerned about the current situation. The safety of the school is directly related to the stability of the entire society and is directly related to The happiness of students and their families. With the security of the campus, digital campus construction has started and security has become an important means of protecting the campus.


LCD splicing screen

Video surveillance and access control applications

in campus security system, video surveillance system with LCD screen can monitor the entire campus classroom building, laboratory building, student dormitories, student cafeteria, main campus entrance and important public places. Through the application of network video and audio monitoring technology, the entire network can be centrally managed and remotely called. In emergencies or alarm events, real-time monitoring through LCD splicing screens improves command and dispatch capabilities.

At present, there are three main applications in the campus video surveillance system . One is widely used in campus safety construction; the second is the management of school buses and the timely monitoring of the safe operation of school buses; the third is examination management, and the “National Education Examination System” required by the Ministry of Education. The establishment of an Internet search through the "video surveillance network covers all the establishment of test centers, the implementation of the monitoring command over the examination process and the security room. From the big screen splicing screen can clearly control the real-time security status of all corners of the campus.

In terms of campus management, we should start from the gates of the campus. Effectively controlling the entry of outsiders is the basic guarantee for campus safety. Access control systems are an important aspect of campus security. Access control helps to strengthen the management and control of students and related personnel on campus. Students and staff access control personnel for identity authentication, access control and management systems, and confirm the pasغير مجاز مي باشدe of time for real-time control and recording, thereby effectively preventing outsiders from interfering with or damaging school safety work. By installing the access control system, management can be promoted, access control awareness and campus safety work responsibility system can be strengthened, visit registration procedures can be strictly followed, and schools can arrange for regular viewing of the LCD splicing screen to achieve effective control of vehicle and personnel entry.

multi-screen

Air defense, anti-technology, anti-

combined for campus security crisis, take the form of civil air defense, physical defense and anti-technology combined, first of all, to strengthen campus security awareness of employees. Through the relevant management regulations, we shall formulate campus personnel restraint behaviors, strengthen safety awareness, and personnel engaged in safety technology prevention shall have the necessary legal basis for professional knowledge, master the basic skills of system operation and maintenance, and master first aid treatment methods.

Strengthen the construction of materials. In the early stages of the campus security system construction and maintenance and reconstruction process, the importance of the protection of campus security systems was fully taken into account. Schools should establish or appoint corresponding management agencies to participate in the school's construction planning and design and construction work. According to the actual situation, they should put forward prevention and use requirements. Pay attention to the application of the security system. Analyze building safety through safety requirements, identify important components of campus guards and common parts, and install video surveillance systems, access control card systems, multimedia teaching systems, intrusion alarm systems, broadcasting systems, electronic patrol systems, and safety facilities. These systems all require a good LCD splicing screen to ensure the safety of children on campus.

LCD splicing screen

From the current practice of all countries in the world, more and more proportions rely on technology for prevention and technology to prevent campus security are growing. For example, in the United States, a full range of electronic LCD screens are provided for campus planning of camera terminals. Each school is related to each other. If a student accident occurs, the large screen will be displayed on the mobile phone simultaneously. The school will also receive a warning. Others Schools will immediately know and take precautions to avoid the killer who causes greater harm.

Therefore, only relying on air defense and physical defense is far from this level, so that campus security should be added with protection technology and reasonable use of safety equipment, establish a unified and standardized electronic monitoring system, and the connection between the system and related departments. Ensure the maximum safety of the school. Emperor Aidi believes that in the rapid development of information technology, campus security and prevention are far from meeting the needs of air defense. They rely solely on materials, and only rely on technology and human and physical defense to ensure the safety of their children. From the current point of view, a security system that is increasingly scientific, effective, and saves manpower and material resources has become a trend as an important means to ensure campus safety and student management.

The significance of advancing the construction of synchronous video recording

The People's Procuratorate's interrogation of duty-related criminal suspects to implement simultaneous recording and video recording means that the People's Procuratorate handles crimes of duty crimes that are subject to direct investigation, and each time a criminal suspect is questioned, it shall perform uninterrupted recordings and videos of the entire process of questioning. Containment of extorting confessions by torture, prevention of defendants from confessions in the courts, strengthening the awareness of civilized case handling, and standardizing law enforcement practices throughout the entire system, synchronized recording and recording systems further standardize law enforcement behaviors, and improve the level of investigation and the quality of case handling.

Efficacy supervision and interrogation eliminated the entire process of objectively recording and rehearsing the interrogation of the entire process of interrogation, strengthened the supervision of the interrogation activities of the investigators, caused a profound change in the law enforcement concepts of investigators, and significantly strengthened the awareness of law enforcement and human rights protection. The consciousness of handling cases according to law and civilization has obviously improved.

Fixing evidence to curb confessions Because many criminal suspects confess the facts of the crime, they attempted to confess their confession on various grounds in order to evade legal sanctions, which seriously affected criminal proceedings. The interrogation of the entire process of simultaneous recording and fixation of the interrogation evidence was completed in a timely and comprehensive manner, which effectively contained the criminal suspect's confession of evidence.

On-scene command, helping suspects with crimes committed crimes with high IQ, criminal means hidden, and investigation difficult. How to seize the subtle changes in the psychology and expression of suspects and effectively cut in and break out of cases is the focus of investigations. In the process of handling case trials, audio and video recordings are performed. Using monitoring techniques and unified operations, the on-site command function can be brought into full play, and the timing of handling cases can be accurately determined. Decisions can be made decisively, and cases can be broken through in time to greatly improve the effectiveness of case handling.

Eliminating hidden dangers and ensuring safe simultaneous audio and video recording can effectively provide insights into the state of criminal suspects throughout the interrogation process, and then prevent and control them more specifically. At the same time, the commanding personnel conduct monitoring through the monitoring room, and can also detect safety hazards in time and prevent safety accidents.

The implementation of the whole-process simultaneous recording and recording system is conducive to curbing confession by torture and preventing the defendant from confessing the confession in court. It also enables the procuratorial personnel to enhance the awareness of lawful, civilized case handling and human rights protection, and further standardize the law enforcement actions; the prosecution agency implements full synchronization. The practice of audio and video recordings has set an example for other specialized agencies such as *, security, and also provided experience for the revision of the Criminal Procedure Law.

Anti-theft alarm system false alarm analysis and fault repair

Alert? Sorry, mistakes ... ... in our country generally believe that: "no danger alarm system alarm signal is false alarm." According to this definition, the false alarm rate of the anti-theft alarm system (in a certain period of time, the system error The ratio of the number of alarms to the total number of alarms is generally above 95%. The definition of false alarms in some Western countries is: “False alarms are actual alarms that do not require* and cause the dispatch of alarm signals, which do not include those due to adverse natural climate and other special environments that cannot be manipulated by alarm companies and users. The alarm signal.” According to this definition, the US UL standard states: “Each alarm system can only have four false alarms per year.”

alarm? Sorry, mistakes... Look at the alarm analysis and maintenance of burglar alarm system
The reason for false alarms is summarized as follows:

1. Alarm caused by malfunction of alarm equipment The product can't complete the specified function under the specified conditions and within the stipulated time. It is called fault. The types of failures are damaging and drifting.

Damaged failures include all failures of performance and abrupt failures. Such failures are usually caused by the damage of components or poor production processes (such as imaginary welding, etc.). Drift faults are caused by the drift of components' parameters and power supply voltage. For example, too high a temperature will cause a change in the resistance value of the resistor. At this time, the device will perform better or worse. In fact, factors such as ambient temperature, component manufacturing process, equipment manufacturing process, uغير مجاز مي باشدe time, storage time, and power supply load may cause changes in the component parameters and cause drift faults.

Whether it is a damaging fault or a drift fault, it will make the system false alarms. To reduce the false alarms that result from this, efforts should be made from the following aspects.

(1) The production enterprise of alarm equipment must improve the design level and technological level of the product. At the same time as the system design, it must also be designed for reliability, such as redundant design, electromagnetic compatibility design, and three-proof design (moisture protection, salt protection) Fog, antifungal, drift reliability design, etc. On this basis, improve the reliability of product manufacturing processes, such as the strict screening of component quality; strict quality supervision and management of the production process, to ensure that product quality meets the requirements of the relevant standards.

Units or individuals that sell anti-theft alarm equipment should carry out strict incoming inspections. The inspection content is: product quality inspection certificate; industrial production license or safety certification certificate or production registration approval certificate of the production enterprise.

(2) The management department shall regularly or irregularly organize inspections and random inspections of the security market, and discover that illegal activities in the production and sale of security product activities shall be handled in strict accordance with the provisions of the “Administrative Measures for the Prevention of Security Technology Products”.

(3) The alarm system construction unit (user) shall clearly require the construction unit to use the products that have been inspected by the authorized testing agencies in the corresponding project documents; the foreign equipment shall use products that have been imported from the regular channels and inspected according to international advanced standards.

(4) In order to ensure the good working condition of the alarm system, a regular inspection and maintenance system must be established. By the way, at present, the maintenance methods of China's alarm system need to be resolved, and it is best to repair the variable-construction unit as the maintenance of a professional maintenance company. This will not only be beneficial to the use of maintenance resources (maintenance personnel, maintenance equipment, maintenance spare parts, etc.) The improvement of the maintenance level, more importantly, can improve the reliability of the security system.

2. The false alarm equipment selection caused by improper system design is the key to the system design. There are a wide variety of alarm equipments and each has its own characteristics, application scope and limitations. Improper selection can cause false alarms. Therefore, to reduce false alarms caused by improper equipment selection, system designers must be familiar with the principles, characteristics, application scope, and limitations of various alarm devices. At the same time, we must also grasp the on-site environmental conditions, climate conditions, electromagnetic field strength, and changes in illuminance in order to select alarm equipment according to local conditions.

In addition to the selection of equipment and equipment, the improper design of the system also manifests itself in the equipment installation location, installation angle, protective measures, and system wiring. For example, when a passive infrared intrusion detector is installed facing an air conditioner or ventilation fan, it will cause a false alarm of the system; if an active outdoor infrared detector is not used for proper sun protection (the sun shield is also best for protection), it is bound to Caused by the system of false alarms; alarm lines and power lines, lighting lines and other strong electric circuit spacing is less than 1.5m, without the protection against electromagnetic interference, the system will also generate false alarms.

3, false alarm caused by improper construction This part of the problem is mainly manifested in the following aspects:

(1) No strict construction according to design requirements.

(2) Improperly installed equipment or improper inclination.

(3) Solder joints have vacant welds, burrs, or shielding measures.

(4) The sensitivity of the device is poorly adjusted.

(5) Inspection equipment for construction does not meet the measurement requirements.

The solution to the above problems is to strengthen the supervision and management of the construction process and implement the safety supervision system as soon as possible. This will help improve the quality of the project and reduce the number of false alarms due to construction.

4, false alarm caused by environmental noise due to environmental noise caused by false alarm refers to the alarm system in the normal state of operation, from the principle is inevitable, but the fact is not needed, is false alarm. For example, thermal airflow causes false alarms from passive infrared intrusion detectors; high-frequency sounds cause false alarms from single-technology glass break detectors; and ultrasonic sources cause false alarms from ultrasonic detectors.

The most effective measure to reduce such false alarms is to use dual detectors (two different detectors detect the “target” at the same time, and the alarm only sends an alarm signal). However, some environmental noise detectors are powerless. For example, rats are in the protection zone; pets move around indoors. For this reason, scientists and technicians have introduced micro-processing technology into the anti-theft alarm system so that they have a certain ability to identify and think, and can judge to some extent whether it is an intruder or an alarm caused by environmental noise.
