Regardless of whether it is commercial or civilian, the access control system is very popular. In the daily procurement of access control products, we should pay attention to what points can be transferred to a suitable cost-effective access control system? Similarly, 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 key tips One, rugged and durable It can be said that access control intercom system is the most important condition, because first of all functionally speaking, the access control intercom system is to protect the user's life and property safety, if Even if it is not strong enough, then how about protecting others? Secondly, the access control intercom system is a necessary place for users to enter and exit, and it is used very frequently. Therefore, users can often hear complaints about the failure of the access control intercom system.

So how do you determine if a product is robust?

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. The power-off 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 damage, the choice of equipment should also pay attention to the performance of the product in preventing man-made damage, such as whether it has a tamper alarm or similar function.

Second, the compatibility users all know that now a large-scale residential units are not only one type, 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, The compatibility/standardization issues caused by inconsistent interfaces 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 to select terminal identification devices that conform to international standards. Some formats have some advantages in terms of locality, but they do not conform to international standards. They will cause problems for future upgrades, expansions, 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, the ability to resist interference 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 attract the attention of 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.

4. The humanized design of access control intercom products is a product for the masses, and humanization is one of the most important features. The humanized design here mainly refers to the user interface of the operation interface, including the indoor unit, the entrance machine, etc. For the purchaser, it is often the children and the elderly who use more, so the operation mode and the operation interface are 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, users should learn more about choosing products. After comparing products, choose products that they like and fit.

Fifth, powerful software management functions With the increasingly wide range of access control systems, requirements and attendance management, security alarm, parking control, elevator control, consumer management, CCTV linkage, online patrol and other systems to achieve linkage control function Therefore, the system software should have a video interface and support extended functions.

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.

In addition to the above five key points, we also need to know the following eight points to purchase a high-performance access control intercom system.

First, strong stability "Stability" is the first principle of the choice of access control system. As far as possible, we should consider the mature products that are in the leading position in the world, pass a number of authoritative certifications, and have many typical users. The industry is highly recognized.

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. The power-off 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, and consistency.

Second, a strong anti-destruction ability Access control system used to protect people and property safety, so the system 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 and the operator's safety. 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 In order to facilitate the future upgrade, expansion and anti-jamming considerations, it is recommended to choose the terminal identification equipment that meets international standards, rather than the compatibility as wide as possible. Some formats have some advantages in terms of locality, but they do not comply with 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 standards”.

Fourth, flexible scalability and economicity The proposed registration card authority needs to reach 30,000, which can be suitable for most of the customer's storage capacity requirements, facilitate attendance statistics and business scale expansion. The main equipments should adopt modular design and adopt advanced wiring methods. Through software and hardware upgrades, future system expansions can be realized without having to make major changes to the system to maximize the economical principle. At the same time, products should be cost-effective.

Fifth, powerful software management functions With the increasingly wide range of access control systems, requirements and attendance management, security alarm, parking control, elevator control, consumer management, CCTV linkage, online patrol and other systems to achieve linkage control function Therefore, the system software should have a video interface and support extended functions.

6. The easy-to-maintain system should be simple and easy to install and configure, simple and popular, and have a unified network management capability, which is easy to maintain.

VII. Purchase of mature brands of mature brand products at the designated agents of the manufacturers can guarantee a perfect and powerful service system. This includes two aspects: first, technical support for the implementation of the project and good after-sales services; second, reliable follow-up research and development capabilities to ensure New and old products have consistency and compatibility.

Buying from agents can have reliable quality and perfect services. Buying from other channels may have lower prices, but technical support and after-sales service may not be enough.

VIII. Appearance of the product With the improvement of people's aesthetic standards, while pursuing functional and practical, one can use its design as one of the reference standards in order to realize the additional functions of visual enjoyment.
