How to choose a reliable and durable access control intercom system has become a problem that many users are concerned about. Next, we will introduce the issues that need attention in the purchase of access control intercom.
Access control intercom to buy five to one, strong and durable
Rugged and durable can be said to be the most important condition of the access control intercom system. First, functionally speaking, what the door intercom system does is to protect the user's life and property safety. If it is not even strong enough, then why? Talk about protecting others? Secondly, the access control intercom system is a necessary place for users to enter and exit. It is used very frequently and therefore users can often hear complaints about the failure of the access control intercom system.
So how do you determine if a product is strong and durable?
It is recommended that users should consider the products of mature brands that are in the leading position in the world as far as possible. On the one hand, they have typical users and their quality has also undergone many tests, and they have been highly recognized in the industry.
In terms of hardware, devices from the controller to the terminal are mature and stable products. As the core of the system, the access controller needs to support the offline mode of operation. It must use flash and other non-volatile memory chips, and the power loss or impact information will not be lost. The failure of the server and terminal to identify equipment does not affect the normal operation of the system. In the case of a lot of man-made destruction, when selecting equipment, it should also pay attention to the performance of the product in preventing man-made damage, such as whether it has tamper alarms and similar functions.
Second, compatibility
Users all know that now a large-scale residential unit is not only a kind of, may be combined with multi-storey, small high-rise, high-level residential buildings of different grades, due to audio and video encoding and decoding algorithms, wiring standards, communication protocols, interfaces are not uniform and The resulting compatibility/standardization issues have plagued buyers. At this time, the multi-system compatibility of the device is required, so that different system requirements are integrated according to different levels of the community, so as to adapt to different user needs.
Therefore, in order to facilitate future upgrades, capacity expansion, and anti-jamming considerations, it is recommended that terminal identification devices comply with international standards be selected, and that the wider and better the compatibility, the better. Some formats have some advantages in terms of locality, but they do not conform to international standards. They will cause problems for future upgrades, capacity expansion, and anti-jamming. They should adhere to the principles of practicality, stability, and compliance with standards.
Third, anti-jamming design
Anti-jamming capability is currently a headache for the building intercom industry. In terms of product quality, anti-jamming capability is urgently needed, especially in some areas where thunderstorms occur frequently. In the field construction, improper selection of wires and irregular wiring may also cause various interference problems. Therefore, it needs to cause widespread concern for product suppliers and construction parties.
At present, the rated voltage of most building intercom door power supplies on the market is 220V, the AC peak or composite voltage is 190-250V, and the test voltage of the anti-electric strength should be 1.5kV. To meet this requirement, it can only meet the requirements of sudden changes in the circuit system, but it cannot resist the lightning overvoltage and excessive current. Therefore, building intercom doors should have lightning protection and grounding devices with good anti-static, anti-lightning, and leak-proof designs, which can avoid many problems in the later use of products.
Fourth, human design
Access control intercom products are products for the general public, and humanization is one of the most important features.
The humanized design here mainly refers to the humanization of the user interface, including indoor units, door machines, etc. For the purchaser, it is often used by children and the elderly. Therefore, the operating mode and interface should be as foolproof as possible. , For example: language prompts, family messages, etc. during the operation; screen graphic interface is more abundant, not just text prompts.
As for this point, users should learn more about the products they purchase, and after they shop around, they can choose the products they like and fit.
Fifth, powerful software management functions
With the increasingly wide range of applications for access control systems, it is required to implement linkage control functions with other systems such as attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage, and online patrol. Therefore, the system software should have video Interfaces and support for extended functionality.
In addition to the above points, there are some keywords like easy maintenance and anti-crash design that users should pay attention to when choosing a door intercom system. It is better to choose a mature brand product so that while ensuring product quality, , but also to ensure the perfect and powerful service system, will save a lot of trouble later.

It should consider the mature products that are in the leading position in the world as far as possible, pass a number of authoritative certifications, and have many typical users. It has been operating for many years and has been highly recognized in the industry.
In terms of hardware, devices from the controller to the terminal are mature and stable products. As the core of the system, the access controller needs to support the offline mode of operation. It must use flash and other non-volatile memory chips, and the power loss or impact information will not be lost. Failure of the server and terminal to identify equipment does not affect the normal operation of the system. As the management software supported by the system, it should have a stable and reasonable database structure design. Between the hardware and the real-time polling method, the communication connection and address of the hardware should be maintained and monitored. Complete data integrity, reliability, consistency.
Second, extremely strong anti-destructive ability
Access control systems are used to protect people and property, so the system itself must be safe. The high security mentioned here refers to the natural or quasi-natural properties of the product or system. It should ensure the safety of the equipment and system operation and the safety of the operator. For example, the equipment and the system must be able to withstand high temperatures and low temperatures. Hot and humid, and can prevent static electricity, anti-jamming, etc.; on the other hand, access control and security systems should also have anti-human damage features, such as: with tamper alarm.
Third, excellent compatibility
To facilitate future upgrades, capacity expansion, and anti-jamming considerations, it is recommended that terminal identification devices comply with international standards be selected, and that the wider and better the compatibility, the better. Some formats have some advantages in terms of locality, but they do not conform to international standards. They will cause problems for future upgrades, capacity expansion, and anti-jamming. They should adhere to the principle of “practicality, stability, and compliance with standardsâ€.
Fourth, flexible scalability and economy
