There are three major factors that restrict the “stability” of building intercom systems

The rapid development of building intercom industry, the number of manufacturers has reached 1,000, the industry's product development line has been more clear: non-visual intercom - black and white video intercom - color video intercom - home smart terminal. From the current point of view, the rapid development of video intercom products has occupied the majority of the domestic building intercom product market, and the non-visual intercom products have gradually lost their market due to the loss of price advantage and their monotonous function. .

The concept of digital intercom has been proposed relatively early. In the past few years, digital intercom products have been in a “tweasy” awkward position. Real estate developers have been waiting and hesitating. With the trend of IP in the security market becoming clearer, this situation has been reversed. Many years of market cultivation have begun to bear fruit. Currently, digital product technology has improved, and product stability, practicality, and reliability have been marketed. test,

It also subverts simple functions such as single call and unlocking of building intercoms in the past, and exerts more outstanding functional advantages. Although the cost is still relatively high, it has ushered in a rapid growth period and is very important in the process of industrialization. One step has been applied in many projects in the market.

There are three factors that restrict the “stability” of building intercom systems, namely point, line, and surface.

"Points" represent building intercom products, including mainframes, extensions, floor exchanges, and networked switches. The core technology and quality control of products are the key to system stability. “Line” refers to the wire and wiring of the system. At present, most building intercom products use the traditional video line plus signal line method. Not only is the wire cost higher and the construction is more troublesome, it is easily disturbed by environmental factors in the transmission process. Affects the stability of the system. “Surface” refers to the networking of the entire building intercom system. The stability of the networking performance is the greatest demand for the stability of building intercom systems. Especially in large-scale community networking, the networking core technology has an important influence on the stability of the entire building intercom system.

Reliability: Reliability reflects the ability of the system to provide continuous service and can be measured by the average time between failures. The longer the average time between failures, the better.

Operation and maintenance services: Operation and maintenance services mainly include the warranty period of each product in the system, whether to provide spare parts, fault response time and maintenance personnel arrival time, service hotline, system inspection cycle and maintenance report.
