[ Huaqiang Security Network News ] With the continuous development of technology, the access control system has changed from an ancient home to an unattended complete access management system. As a must-have for family protection, how to choose the most suitable access control intercom system?
It is recommended that users should consider products of mature brands that are world-leading as much as possible. On the one hand, they have typical users, and the quality has withstood many tests and has been highly recognized in the industry.
First, in terms of hardware, the identification device from the controller to the terminal is a mature and stable product. As the core of the system, the access controller needs to support the offline working mode. It must use a non-volatile memory chip such as flash. The power loss or impact information will not be lost. Server and terminal identification equipment failure does not affect the normal operation of the system. For many people to damage the situation, you should also pay attention to the performance of the product in the prevention of human damage, such as whether there is a tamper alarm and other similar functions.
Second, compatibility users know that there is not only one type of large-scale residential apartment, and it may be a combination of multi-level, small high-rise, high-rise and other different grades of residential, due to audio and video codec algorithms, wiring standards, communication protocols, 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 grades of the community, thereby adapting to different user requirements.
Then, in order to facilitate future upgrades, expansion, and anti-interference considerations, it is recommended to select terminal identification devices that conform to international standards, rather than the compatibility as wide as possible. Some formats have some advantages in part, but they do not conform to international standards. They will cause troubles for future upgrades, expansions, and anti-interference. They should adhere to the principles of practicality, stability, and compliance with standards.
Third, the anti-interference design anti-interference ability is a common headache in the building intercom industry. In terms of product quality, anti-interference ability is urgently needed to be improved, especially in some areas where thunderstorms occur frequently. In the field construction, improper selection of wires and irregular wiring will also cause various interference problems. Therefore, it is necessary to cause widespread attention from product suppliers and construction parties.
At present, the rated voltage of the main building intercom power supply is 220V, the AC peak or combined voltage is 190 ~ 250V, and the test voltage of the 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 attack of lightning overvoltage and super-current. Therefore, the building intercom door should have lightning protection device and grounding device with good anti-static, lightning-proof and anti-leakage design, which can avoid many problems in the later use of the product.
Fourth, humanized design Access control intercom products are products for the public, the humanization of use is one of the most important features. The humanized design here mainly refers to the humanization of the operation interface, including indoor unit, door machine, etc. For the purchaser, it is often used by children and the elderly, so the operation mode and operation interface are as foolish as possible. For example, language prompts during operation, family messages, etc.; screen graphical interface is more abundant, not just text prompts.
As for this, users should know more when purchasing products. After shopping for three products, choose the products that you like and suit.
With the wider application range of the access control system, it is required to implement the linkage control function with other systems such as attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage, online patrol, etc., so the system software should have video. Interface and support for extended functionality.
In addition to the above points, there are some keywords like easy maintenance and anti-crash design that users need to pay attention to when choosing the access control intercom system. It is best to choose mature brand products, so as to ensure product quality. It also guarantees the perfection of a strong service system, and will save a lot of trouble later.
Summary: Only the sturdiness of the access control intercom system can guarantee the protection of family safety in the later period.
