Just Teaching Lesson 3: Choosing the Key to the Access Control System

The film biochemical crisis, a Hollywood commercial system adapted from the same name game, was popular at the beginning of the release. It could even be said that it opened the door to the US zombie theme movie, which has a far-reaching impact on the subsequent American movies and TV series. Then Xiaobian, who is the security guard, was not interested in the violent bloody killing shots but the super computer of the hive laboratory in the movie. At the beginning of the movie, the director demonstrated to the audience that under the control of artificial intelligence, the intelligent access control system deals with the danger. Although the means and results are not satisfactory, it is undoubtedly a guess for the intelligent access control system. However, this conjecture is more like a prediction and a prediction of the development of the access control system.

However, in the movie, "Red Afternoon" still maintains sufficient electric power in the case where the entire laboratory is completely blocked and no one operates. This obviously depends on its complete power supply system. However, does the power supply of a smart access control system in real life withstand the harsh tests?

The intelligent access control intercom system involves a large number of devices that need to be powered. In order to ensure that each device can operate normally and stably, the power supply needs enough power to supply power to each device. When purchasing the power supply, pay special attention to the nominal value of the power supply, and test the actual parameters in the field. Because there are some low-cost access control power supplies in the market, they often do not reach the nominal value in practical applications, which seriously affects the intelligence. The normal operation of the access control intercom system. It is recommended that when selecting the power supply, select the power supply manufacturer with technical parameters, reliable quality, good reputation, and suitable for smart door intercom systems. At present, there are some manufacturers of access control systems, and the power supply is sold together with the controller. Generally, such manufacturers consider the actual application of the project for power supply selection, and have better protection for the overall quality of the system.
