Ten faults in the building intercom system how to solve

April 04, 2023
Compared with other projects, digital building intercom systems have large input costs and long recovery cycles. They all have high requirements for technology, experience, and maintenance. Weakness in any one link is a factor that causes instability in building intercom systems. . Analyzing the current situation, the building intercom system mainly has the following defects:

First, anti-jamming capability: Anti-jamming 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 attract widespread attention from product suppliers and construction parties.

Second, the signal attenuation: usually video amplifiers to solve the problem, but at the same time lead to distortion problems. If the wire is not properly selected, signal attenuation will occur.

Third, networking features: Bus and TCP / IP can be networked. The bus is still the mainstream at present, the networking function is relatively simple, and the transmission distance is limited, which is unfavorable to large-scale networking.

Fourth, compatibility / standardization: due to audio and video encoding and decoding algorithms, wiring standards, communication protocols, interfaces caused by the compatibility / standardization issues have been plagued the purchasers, this part is still subject to relevant departments to promote the development of relevant standards.

Fifth, audio and video transmission delay: mainly in the TCP / IP networking, vendors should continue to optimize the algorithm, so that faster transmission speed and audio and video quality.

6. Noise Control and Echo Cancellation: Mainly voice processing still requires manufacturers to optimize the algorithm, and the processor needs to provide more flexible and powerful voice support.

VII. Integrate more functions: Some users think that intercom products can abide by their responsibilities, and the simpler the function, the better; while some users want to integrate more functions. In this regard, manufacturers should seek truth from facts and correctly guide users' sense of procurement.

VIII. Humanized design: Mainly refers to the user-friendly interface, including indoor units, door machines, etc. Procurementists want the product to be as fool-proof as possible, so that children and the elderly are easy to understand and operate, such as voice prompts during operation. Family messages, etc.; screen graphics interface more abundant, not just text prompts.

Nine, better picture quality: mainly the color intercom display presence clarity, color, saturation and other issues. According to purchasers, some manufacturers choose some used screens to save production costs. Developers and contractors do not know. Normally, there will be no problems within one year. You may want to replace all of these displays after one year.

X. Cost Reduction: Although analog intercom products are still the mainstream of the market, digital intercom is the future development trend. However, compared with the price, the price of digital products will be much higher than the simulation, which is one of the reasons why digital products are difficult to popularize. So, how to reduce the cost of digital products is an urgent problem that manufacturers need to solve.
