Residential access control system is the first line of defense for indoor safety.

With the continuous development of society, safety becomes more and more important. As a guarantee for the increase of business volume, strengthening the security of the community will be an important means to ensure the good development of the community. Access control system is an important part of community safety. It can not only change passive defense into active control through access control, but also greatly reduce the workload of property management. What are the advantages and disadvantages of community access control system? What are the functional characteristics of residential access control system? Let me introduce you to the relevant knowledge of community access control system.

Introduction of access control system

Door is the first and most important line of defense for indoor safety, and strengthening door safety management is the most important measure to ensure indoor safety. Literally, the access control system is a system that sets forbidden permissions for the entrance and exit of doors. Broadly speaking, the access control system includes all management systems that set access rights, such as doors for people to enter and exit, doors for vehicles to pass, and other access control systems. From a professional point of view, the so-called access control system is actually a system for managing exit passages.

Universal access control system is a system composed of various machines and equipment, and different machines and equipment play corresponding roles. At the same time, it will also be applied to computer technology, internet technology, optical technology, mechanical technology, biotechnology and other technologies. Therefore, the access control system is also a high-tech system. Usually, the access control system consists of identification, sensing and alarm, processing and control, electrical locking and execution, wiring and communication, management and setting. All these parts cooperate with each other to complete the safety management of the entrance and exit of the gate.

Functional characteristics of community access control system

First, multiple authentication modes are selected.

Mode 1: One-way verification:

After the user is authorized to identify and confirm the legal identity outside the door, the controller drives to open the electric lock and records the time of entering the door. Press the door open button, open the electric lock and go straight out.

It is suitable for the environment with general security level and can effectively prevent outsiders from illegally entering. It is the most commonly used management mode.

Mode 2: two-way authentication:

After the user is authorized to identify and confirm the legal identity outside the door, the controller drives to open the electric lock and records the time of entering the door. When the user leaves the controlled room, he should also show his authorized identity in the door, and then the controller will drive to open the electric lock and record the time of going out.

It is suitable for the environment with high security level, which can not only effectively prevent outsiders from illegally entering, but also inquire about the last person and time to leave, facilitate the implementation of responsibilities and provide evidence (such as theft) in a specific period.

Second, there are many ways to confirm legal identity.

Pattern 1: a kind of verification:

People who need to verify someone's legal identity can confirm their legal identity by providing verification methods or fingerprint verification, password verification or card verification:

It is suitable for the environment with general security level and is the most commonly used management method.

Mode 2: Two types of authentication:

People who need to verify someone's legal identity must provide two verification methods, fingerprint+password verification or card+password verification, in order to confirm their legal identity:

It is suitable for the environment with high security level, and the two verification methods restrict each other to improve the security level (password is required for compulsory verification such as finger cutting).

Mode 3: Three types of authentication:

People who need to verify someone's legal identity must provide three verification methods or fingerprint+password+card verification to confirm their legal identity:

It is suitable for the environment with extremely high security level, and the three verification methods restrict each other to improve the security level.

Function of residential access control system

1 The entrance guard of the community has a certain identification system, and only residents with cards can enter, so the entrance guard can prevent some non-community personnel from entering the community at will, creating a good environment for the community.

Especially in the morning, middle and evening rush hours, it is easy for people such as idle people to enter the community, especially those who have ulterior motives for the property of the residents in the community, which is easy to pose a certain threat to the life and property safety of the residents in the community. The access control of the community can identify everyone who enters the community in an orderly manner, and at the same time, it can avoid the phenomenon of crowding at the gate and reduce the accidents caused by crowding.

The execution of access control system in the community can greatly enhance the image of the whole community. High-grade access control system can also display and improve the management level of the community, which can not only meet the safety needs of residents, but also greatly improve people's quality of life to a certain extent.

The access control system of No.4 residential area is more convenient and faster than the previous access control system. People don't have to carry the key to the gate with them as before, or they are always worried about missing the access time when they are outside. Moreover, the access control system in the community is more secure than the key, and even many high-end communities have adopted fingerprint access control systems, which greatly improves the security of the community.

The entrance guard of the community can identify and store the information of the people entering and leaving. When an accident happens, the alarm system will automatically start, and its management system has very clear records and monitoring. If it is very convenient to retrieve, it can also provide great help for the investigation of the later situation.

Quotation of residential access control system

The quotation of residential access control system should also consider the brand price of each configuration component. The same type of configuration, due to different brands, the price may vary greatly. In addition, the configuration of access control system in different occasions is also very different.

Common faults and solutions of residential access control system

1 sometimes the door can't be opened by intercom in the access control system. The main reason for this phenomenon is generally poor contact between signal receiving and transmitting. You can try to check whether the power and wiring of the walkie-talkie are normal. It is also possible that the electric lock is broken, and sometimes there is something wrong with the wiring of the residents, which may affect the situation that the intercom cannot open the door. Check the wiring at home.

When the management machine and the intercom at the door work at the same time, there is a lot of noise. This situation is generally caused by two reasons, ranging from improper volume adjustment to wiring problems. Just check the tests separately.

When the household swiped the card, the machine didn't respond. This situation is a common and troublesome fault for many reasons. On the one hand, it may be because the resident magnetic card is not well protected in daily use, resulting in serious wear and tear, or because of long-term contact with mobile phones, computers and other cards, resulting in serious demagnetization, resulting in the card reader can not obtain information normally when swiping the card. On the other hand, there may be a problem with the card reader. It may be because the power supply of the card reader is unstable or insufficient, or it may be because the card reader is worn out and cannot work normally due to long-term use. Otherwise, there may be an internal fault in the card reader, which needs to be checked by professional maintenance personnel.

4 The power indicator light is easy to go out. This may be caused by power shortage or insufficient voltage. Check the circuit protector. It is also possible that the card reader line is short-circuited. First, confirm whether the input end of the external power supply is normal or test the voltage.

5 Under normal power-on, the card reader has continuous abnormal sound. This may be caused by the virtual connection of the power cord or the incorrect cable connection between the controller and the card reader. Try to check the cable and power cord.
