According to analysis, the building intercom system mainly has the following defects: Anti-interference ability: Anti-interference 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 attract the attention of product suppliers and construction parties. Signal Attenuation: Usually video amplifiers are used to solve the problem, but at the same time cause distortion problems. If the wire is not properly selected, signal attenuation will occur. Networking: Both the bus and TCP/IP can be networked. The bus is still the current mainstream, the networking function is relatively simple, and the transmission distance is limited, which is unfavorable for large-scale networking. Compatibility/standardization: The compatibility/standardization problem caused by the inconsistency of audio and video codec algorithms, wiring standards, communication protocols, and interfaces has been plaguing purchasers. This part is still waiting for the relevant departments to promote the development of relevant standards. Audio and video transmission delay: mainly in the TCP/IP networking mode, vendors should continue to optimize algorithms and other aspects to achieve faster transmission speed and audio and video quality. Noise control and echo cancellation: Mainly for voice processing, manufacturers still need to optimize algorithms, and processors need to provide more flexible and powerful voice support. Integrate more features: Some users think that the intercom products can be responsible for the functions, the simpler the better, and some users want to integrate more functions. In this regard, manufacturers should seek truth from facts and correctly guide users' purchasing awareness. User-friendly design: mainly refers to the humanization of the operation interface, including indoor unit, door machine, etc. The purchaser wants the product to be as foolish 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 more abundant, not just text prompts. Better picture quality: mainly the color intercom display has problems such as sharpness, color, saturation. According to the buyer's reaction, some manufacturers choose some second-hand screens in order to save production costs, developers and engineering companies do not know. Generally, there will be no problem within one year, and all of these displays may be replaced after one year. 3D Water Steam Fireplace,3D Water Fireplace,Small Water Steam Fireplace,Water Steam Fireplace Without Heat JINAN LODOR CNC EQUIPMENT CO.,LTD , https://www.zgfireplace.com
