Top Ten Disadvantages of Building Intercom System
There is a high level of demand. The thinness of any link is an element of instability in the building's intercom system. Analyzing the current situation, the building intercom system has the following shortcomings:
Anti-harassment skills: Anti-turbulence is a question of headaches in the current building intercom. In terms of product quality, the ability to resist turbulence is urgently needed, especially in some areas where thunderstorms are frequent. In the field construction, improper selection of wires and irregular wiring may also cause confusion. Therefore, it is necessary to cause the attention of commodity suppliers and construction parties.
Signal attenuation: Usually video amplifiers, etc., deal with questions, but together they cause distortion. If the wire is not properly selected, it will show signal attenuation.
Networking functionality: Both the bus and TCP/IP can be networked. The bus is still the current main stream, the networking function is relatively simple, and the transmission interval is limited, which is a large-scale networking evil.
Compatibility/standardization: Due to the inconsistency of audio and video codec algorithms, cabling specifications, communication protocols, and interface inconsistencies, compatibility/standardization questions have always puzzled acquirers, and some of these are still waiting for the relevant authorities to advance the association specification.
Audio and video transmission delay: First of all, under the TCP/IP networking method, vendors should continue to optimize algorithms and other aspects, so as to achieve faster transmission speed and audio and video quality.
Noise Control and Echo Cancellation: First and foremost, voice processing still requires vendors to optimize algorithms, while the processor needs to provide more responsive and robust voice support.
Integrate more functions: Some users think that the intercom products can follow the responsibility, the simpler the function, the better; and some users expect more integration. In this regard, manufacturers are probably down to earth, correctly guiding users to acquire knowledge.
Humanized depiction: mainly refers to the user interface of the user interface, including indoor units, door machines, and so on. The purchaser expects the product to be as fool-proof as possible, so that children and the daytime are easy to understand and operate. For example: voice prompts during the operation, family Messages, etc.; screen graphic interface more abundant, not just text prompts.
Very good picture quality: First and foremost is the question of the sharpness, color, saturation, etc. of colorful intercom displays. In addition, according to the buyer’s response, some manufacturers chose some used screens in order to save production costs. Developers and contractors did not know. Usually within one year, there will be no doubt. After one year, all of these screens will be replaced.
The capital decline: Although the current imitative intercom products are still mainstream shopping malls, digital intercom is the future trend. However, as far as the price is concerned, the price of digital goods will be much higher than that of imitation, which is one of the reasons why digital goods are difficult to spread. So, how to reduce the cost of digital goods is a question that manufacturers need to urgently handle.
Building intercom system has a high rate
To sum up, there are three types of users of these products: First, the government, enterprises and institutions of the alarm and monitoring system, the second is the public place monitoring alarm system, and the third is the community residents of building intercom, alarm monitoring system. The rate of integrity of the former two systems is greater than that of the latter, and first and foremost is that they have a professional-like system to protect the company’s staff. However, an interesting phenomenon is that the community residents who use the building intercom system are not direct purchasers of goods, and it is precisely the highest rate of building intercom systems. Where does the question lie?
1, consumers have no right to choose goods
The building intercom system is a very special commodity in domestic shopping malls: it is not the people who spend money, but the resolution of real estate companies. Therefore, users and consumers do not have the opportunity to select products. Since the time the user bought the house, the real estate agent is now installed. The quality of goods is good or bad, and whether individuals are like it or not, consumers are completely ignorant. What makes users more and more unable to do so is that the quality of the house is regulated by regulations that are related to it, and the building intercom system is only an accessory of the house and there is no related decree to restrict it.
2, building intercom manufacturers rely on real estate business
It is precisely because of this unbalanced relationship that building intercom companies understand that real estate companies need to rake in commodities, and building intercom companies produce a variety of products to meet the growing needs of real estate developers. There are tens of thousands of senior commodities and tens of ordinary commodities. Some building intercom manufacturers who do not wish to reveal their names have said that they are facing a dilemma. Why? Building intercom manufacturers rely on the start-up of real estate developers. Even so, assuming that the real estate development has stagnated, it is difficult for building intercom manufacturers to start. Therefore, the products we produce are not available at the mall. The right to speak.
3, manufacturers can not become "scapegoats"
In the entire intelligent community construction, only the building intercom products can reach each family, and can establish the most direct contact with the handling office; together with the long-distance interactive service system through the center, so consumers most directly see The use of the building is the intercom door and indoor unit. When in doubt, the “recruitment list†is affixed to the building intercom product. In fact, the building intercom system includes both doorways and indoor units, as well as cables, power supplies and other commodities. What is more important is the system's depiction and construction. It is only necessary for a part of the system in question to be unable to function properly. .
What is more, property developers repeatedly push down prices, causing the building intercom companies to assume responsibility for the entire system’s functioning as a “scapegoat†when they have little profit, and real estate developers sell out houses. Take the buttocks and take the money to steal.
4, how to protect consumer rights is a question
Consumers who use commodities are not buyers of commodities. What's more, this is a highly integrated system that involves all aspects. The system presents doubts and can't know who it is. According to the R&D Department of Nanjing Chulin Intelligent Technology Co., Ltd., there are rules on the use of life span for goods, and some system operations are attributed to a long period of time and to the period of system transformation. The classification of the responsibilities of the alarm monitoring and building intercom system within the warranty period should be from the probabilistic order: commodity producers, system installation engineers, property management companies, residential property owners, etc. The responsibilities of commodity producers are mainly attributed to the fact that the quality of goods is low or the functional and functional specifications do not meet the operational needs, causing frequent system failures, which in turn leads to a collapse of the system; the responsibilities attributed to the contractors are now irrational and the construction wiring is in danger. The use of fake and shoddy goods, poor after-sales service has led to small doubts caused big doubts, etc.; property management companies may protect the company's system's responsibility is to generally poor protection of the system, the nature of skills is low, not familiar with the system, there is no repair funds for normal Operational protection of the system; the ability to attribute to the owner’s duties is very small.
Therefore, the vast majority of the system is due to the failure to find engineering integrators and product manufacturers, and the property company has not carried out system protection, resulting in damage to consumers' rights and interests.
Pay attention to the normal protection of the system
From the above analysis, it can be seen that the responsibility of building intercom and alarm monitoring system can be caused by many parties. Therefore, the first priority is to strictly control the quality of goods, together with the construction of contractors, and ultimately, the careful protection of the system is also necessary.
Pay attention to the normal protection of the system or reduce the rate of intercom
Building intercom systems, city alarms and surveillance constructions have now begun in the 1980s. They were first used in urban transport, important units and some high-grade residences. These systems have experienced three construction climaxes: First, the construction of a single project initiated by the affiliated units in the mid-to-late 1980s; second, the construction of a system built around communities and communities in the mid-to-late 1990s; and thirdly, since 2003. The Department of Beginnings* initiated the construction of government-initiated, operational, and administrative security alarm and monitoring systems for social security in the country. This is also known as the “3111†project. Nowadays, many places have set up channels for urban dynamic monitoring and alarm networks, forming a full-scale, three-dimensional skills defense network that covers key units, residential quarters, public places and mobile policies.
