Building intercom defects

defect

According to analysis, there are the following shortcomings in building intercom:

Anti-jamming capability: Anti-jamming is a common headache in the building intercom industry. In terms of product quality, anti-interference ability is urgently needed to improve, especially in some thunderstorm-prone areas. In field construction, improper selection of wires and irregular wiring will also cause various interference problems. Therefore, it needs to attract the general attention of product suppliers and construction parties.

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

Networking function: Both the bus and TCP / IP can be networked. The bus is still the mainstream, the networking function is relatively simple, and the transmission distance is limited, which is not conducive to large-scale networking.

Compatibility / standardization: Compatibility / standardization problems caused by the inconsistency of audio and video codec algorithms, wiring standards, communication protocols, and interfaces have always plagued buyers. This part is still waiting for the relevant departments to lead the development of related standards.

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

Noise control and echo cancellation: Mainly in terms of voice processing, manufacturers still need to optimize algorithms, and processors need to provide more flexible and powerful voice support.

Integrate more functions: Some users think that the intercom product can abide by its duties, and the simpler the function, 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.

Humanized design: mainly refers to the humanized operation interface, including indoor units, door phones, etc. Buyers want the product to be as fool-proof as possible, so that children and the elderly can understand and operate easily, such as: voice prompts during operation, family messages Etc .; the screen graphical interface is richer, not just text prompts and so on.

Better picture quality: mainly the color intercom display has problems with sharpness, hue and saturation. According to feedback from buyers, in order to save production costs, some manufacturers choose some second-hand screens, and developers and engineers do not know. Generally, there will be no problem within one year, and all of these displays may be replaced after one year.
