Supply video linkage alarm system, network alarm, network alarm system

Due to the many advantages of the networked alarm system, it is currently widely used, and coastal areas are especially at the forefront of the country. Since the use of the networked alarm system, the rate of window prying, lock prying, door prying and other crimes among users who have accessed the network has been greatly reduced, effectively ensuring the safety of people's lives and property. At present, the centers of urban networked alarm systems are mainly located in public security bureaus and police stations. The users are mainly banks, shops, factories, office buildings, entertainment venues, etc. In addition, the head office in the financial banking system is the center, and other branches and savings banks are the users. With the development of society and the improvement of living standards, various commercial buildings and residential areas are also realizing the necessity of installing alarm systems. The people's needs in this regard are becoming more and more urgent, so the center is set up from the beginning Public security bureaus and police stations are gradually transferred to commercial buildings and residential communities. The managers of commercial buildings or residential communities directly dispatch police. This not only dispatches police more quickly, but also reduces the huge pressure on the public security bureaus and police stations due to the large number of users. , from a long-term development perspective, the solution of using residential areas, factories, mining enterprises, and commercial buildings as local networking centers and using secondary networking methods to transmit police information to urban networking centers will be widely adopted.


, The composition of the technical prevention system

The technical prevention system we refer to here is an electronic alarm system, which uses electronic judgment in an unattended place. In case of illegal intrusion, fire or other emergency rescue events, an alarm will be automatically issued at the scene, and the alarm information will be automatically transmitted to an alarm center that specializes in handling the alarm situation. The electronic anti-theft system does not require manual participation to alarm. It is fundamentally different from the voice alarms in our common alarm centers. It is also different from technical defense methods such as closed-circuit television monitoring, security doors, and intercom doorbells that require manual participation. A purely technical means of prevention with fully automatic action. Usually, a complete regional anti-theft system consists of two parts: the user-side alarm system and the alarm center.


, User-side alarm system

The user-side alarm system is an alarm system that constitutes the safety of personnel and property for various types of users. The actual situation of different users affects the scale and function of the system, but it is distinguished by input, control, and output. Its functional structure is nothing more than the following three parts: input part, control part, output part

An alarm system Whether it is good or bad usually depends on the engineering design selected for the system, the rationality of the installation and the reliability of the equipment. Therefore, we must first have a comprehensive understanding of the functions of these three parts.


,

In the input part of the system, various types of intrusion behaviors, such as human body movement, object vibration, glass breakage, door and window switches, etc., the system will The resulting signal is subjected to some logical judgment and an alarm is issued. Because the alarm system is based on the alarm, choosing a suitable and reliable one is often the guarantee that the alarm system is reliable and effective and reduces false alarms.


Alarm control/communication host

In the entire anti-theft system, the alarm control/communication host is like the human brain and is the processing part of the entire system. The alarm control/communication host makes a logical analysis of the status (arming/disarming) and then issues an alarm. The function of an anti-theft alarm system is mainly reflected in the function of the alarm host. The following is a basic alarm host system structure. The alarm control host can be understood from the following aspects

Defense zone function A defense zone is the smallest unit that we can identify in the alarm system. For example, a defense zone can contain multiple , these, we can only know that this defense zone has alarmed, but at this time we can no longer know which of this defense zone it is. Therefore, in an alarm system, we can only identify defense zones.

An alarm host can usually connect to multiple defense zones, and the zone type of each zone can be set. The number of defense zones is usually the primary indicator for people to design an anti-theft system, and it is also the primary difference between various host models. Most multi-defense hosts do not have many basic defense zones, and other additional defense zones are added through zone expansion. Generally speaking, the basic defense areas of the host computer all use wired probes with switch-type output, while the expanded defense areas vary depending on the model. They are generally divided into three forms: wired, bus, and wireless

Wired expansion is the addition of the host The defense zone expansion board is connected to a conventional four-wire probe (that is, a switch-type signal output probe, which has two wires and two power lines to increase the defense zone. This expansion method simply increases the number of defense zones. Without adding new functions to the system.

The wireless expansion host is coupled with a wireless receiver and a matching wireless probe. Using this expansion method can achieve the purpose of easy installation without damaging the original building. , you can also use wireless buttons to achieve the functions of remote control switch and remote arming and disarming.

The bus expansion host can directly connect to the two-wire bus system probe (addressing signal output, power supply and signal share the core wire and all Bus probes are connected in parallel, making the access line more concise, especially suitable for situations with a large number of defense zones. In order to take advantage of the ease of bus installation and use conventional four-wire probes, you can use what is often called bus expansion. The encoder of the encoder. In addition to being used in large systems, this expansion method also plays a role in reducing costs and reducing the amount of engineering when connecting defense zones over long distances (up to meters, depending on the diameter of the cable used.

, Operation functions

Basic operations include arming, disarming, etc. Generally, the operations of the host are performed through the keyboard,


, Output function

On-site sound and light alarm output, telephone network alarm. After an alarm occurs, the host can remind people's attention through a variety of means. The early hosts only had on-site alarms, but now most hosts can The alarm signal is transmitted to the alarm center through the public telephone system to handle the alarm situation.


, / flashing light output

or flashing light is the output part of the alarm system, When an alarm occurs at the user site, the alarm output of the control host drives the siren or flashing light to emit audible and visual signals to attract people's attention and scare away thieves.

However, international experience now shows that when When anti-theft systems are commonly used, there are many false alarms caused by operation or equipment, and people gradually become accustomed to alarms. As a result, alarms no longer attract the attention of most people. Therefore, specialized personnel are needed to handle alarm situations, which requires alarms. The signal is transmitted to the police processing center──alarm center through a certain method.


, Alarm center system operation mode

Modern digital alarm technology is the alarm host generated After the alarm, the alarm information is encoded into a digital signal through the communicator and transmitted to the remote digital alarm center receiver via the communication network. Digital alarm technology can avoid human operating factors, is fast, has a large amount of information, and can be received according to the The digital information identifies which user is in which location (defense zone) and which alarm occurs, which can provide detailed user information to the alarm center and make a quick response. And with the use of a computer, not only can the user's detailed information be automatically called up and printed out, but alarm signals can also be saved to facilitate future query statistics.


Alarm center work flow

) Inspect the location of the intrusion device according to the prescribed time program every day

) and user alarm control device to communicate. If no one answers, contact the police station under your jurisdiction and indicate the address and location of the alarm equipment, promptly confirm the alarm situation. If someone answers, check the user verification code, communicate with the user, analyze the cause of the alarm, and find the source of the false alarm

) The early warning center promptly registers, archives and provides feedback on each police station’s police information or communication with users

) The early warning center records various alarms that join the center every quarter Equipment usage, mainly the actual reporting rate, usage rate, false alarm rate, failure rate and alarm rate of the equipment are comprehensively analyzed and summarized, and fed back to each user

) The early warning center monitors the joining rate every month Various alarm equipment in the center will be provided with one or two on-site inspections, maintenance and other after-sales services

) According to user requirements, the early warning center will provide users with a detailed list of equipment usage and alarm information every month.


Alarm center service model

) Users register basic information, sign an alarm power of attorney with the early warning center, and set an alarm verification code. At the same time, the insurance company will respond to user requirements Issue the corresponding insurance policy

) Install a networked anti-theft alarm system

) The client connects to the early warning center and transmits relevant information to the receiving center of the police station under its jurisdiction

) Under normal circumstances, the early warning center monitors all participating user systems around the clock, and receives user information on normal arming and disarming, equipment and communication usage

) Alarm After the information occurs, the early warning center and the police station under its jurisdiction receive the alarm signal from the user at the same time. Generally, the early warning center analyzes and filters the authenticity of the alarm within the first time. The police station under its jurisdiction receives the alarm signal from the early warning center. Emergency alarms and hijacking password signal alarms will be handled directly by the police station under the jurisdiction of the police station after effective police notification.

) In order to ensure the economic interests of users, the telecommunications department and insurance companies intervene in advance in the socialized networked anti-theft alarm system The construction, use, maintenance and management of the system, and the insurance claims arising therefrom will be settled by the early warning center together with the users based on the policies issued by the insurance companies.


, insurance claims

The insurance amount and term are based on the terms of the insurance company. The general insurance is home property insurance (each 10,000 yuan plus personal accident insurance ( The total insurance amount is RMB 10,000 per policy. The insurance period is generally one year, and can be renewed according to actual needs.

Scope of insurance compensation liability

According to the insurance company According to the terms, the scope of general insurance compensation liability is

Only property and personal accidental injury losses covered by the home security system facilities of the insurance company's cooperative unit fall within the scope of insurance compensation liability.

. Loss of insured property caused by a series of reasons under the normal use of the home security system facilities of the insurance company's cooperative unit. (For the series of reasons, please refer to the relevant clauses in the insurance company's policy)

, Location The address stated in the insurance company's policy and the household property stored in the room at the insured address.

Under the normal use of the home security system facilities of the insurance company's cooperative unit, due to an insured accident occurring on the insured property Disability or death caused by accidental injury to the insured.

, specially insured property, such as cash (yuan per share) and gold and silver jewelry (yuan), etc.

, Clothing, bedding, furniture, cooking utensils with an actual value of more than 1 yuan and household appliances and musical instruments with an actual value of more than 1 yuan and a fixed volume greater than cubic centimeters are within the scope of insurance liability.

Other insurance clauses are covered by insurance. The scope of liability compensation and those that do not fall within the scope of insurance liability compensation are based on the actual policy terms.

Insurance compensation procedures

When the user is using the home security system of the insurance company's cooperative unit normally In the case of facilities, if property or personal accidental injury occurs, the case should be reported to the public security department and the insurance company in a timely manner.

The user should provide all documents (including the insurance company's cooperative unit should provide the user's home security Proof of the use of the system facilities when the case occurred, as well as relevant certificates from the public security department and the validity of the user's property lost) to make insurance claims.

If the user provides incomplete documents, the insurance company can make a decision based on the actual situation. Whether to accept insurance claim cases. Generally, the insurance company may not accept the insurance claim case without relevant certificates from the public security department and certificates from the insurance company's cooperative units. If the single lack of valid property loss is valid, the insurance company can make a claim on the basis of the other two certificates. The user accepts the insurance claim case, and the claim is paid at a discount (approximate discount) according to the insurance company's standard.

The insurance company should accept the insurance claim case on the basis of complete documents provided by the user, and the insurance claim is settled according to the insurance company's standard Compensation will be paid according to the policy terms and conditions, and the compensation will generally be paid within one working day.
