Compared with other projects, the digital building intercom system has a large investment cost and a long payback period. It has high requirements for technology, experience, and maintenance. The weakness of any link is a factor that causes the instability of the building intercom system. . Based on the analysis of the current situation, the building intercom system mainly has the following defects:


        1. Anti-interference ability: Anti-interference is a common headache problem in the building intercom industry. In terms of product quality, anti-jamming capabilities are urgently to be improved, especially in areas prone to thunderstorms. In the field construction, improper wire selection and irregular wiring can also cause various interference problems. Therefore, it needs to attract the general attention of product suppliers and construction parties.


         2. Signal attenuation: usually video amplifiers are used to solve the problem, but at the same time cause distortion problems. If the wire is not selected properly, signal attenuation will occur.


         3. Networking function: Both 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 not good for large-scale networking.


          4. Compatibility/standardization: Compatibility/standardization issues caused by the inconsistency of audio and video codec algorithms, wiring standards, communication protocols, and interfaces have been plagued by purchasers. This part is still to be led by relevant departments to promote the formulation of relevant standards.


          5. Audio and video transmission delay: mainly in the way of TCP/IP networking, manufacturers should continue to optimize algorithms and other aspects to obtain faster transmission speed and audio and video quality.


          6, noise control and echo cancellation: mainly the voice processing still needs to optimize the algorithm of the manufacturer, and the processor needs to provide more flexible and powerful voice support.


          7. Integrate more functions: Some users think that it is enough for intercom products to 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 to purchase awareness.


           8. Humanized design: Mainly refers to the humanization of the operation interface, including indoor units, door phones, etc. Purchasers hope that the products are 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.; the screen graphical interface is richer, not just text prompts, etc.


           9, better picture quality: mainly because the color intercom display has problems such as clarity, color and saturation. According to the buyer's response, some manufacturers choose some second-hand screens in order to save production costs. Developers and contractors do not know. Generally, there will be no problems within one year, and all these displays may be replaced after one year.


           10. Cost reduction: Although analog intercom products are still the mainstream in the market, digital intercom is the future development trend. However, in terms of price, the price of digital products is much higher than that of analog products, which is one of the reasons why digital products are difficult to popularize at present. So, how to reduce the cost of digital products is a problem that manufacturers need to solve urgently.
