How to deal with cable companies with security as the main market

Wire and cable are involved in many industries in China. The product variety satisfaction rate and domestic market share exceed 90%. With the nationwide safe cities, intelligent transportation, and smart cities, the projects are widely concerned and vigorously constructed, with the exception of key developed cities’ security needs. As the market continues to expand, the markets in the central and western regions and second and third tier cities are also extensive. Security cables play an important role as an important link between security devices. The emergence of analog high-line, HD-SDI cameras and other products have had a significant impact on the security cable companies. At the same time, the cable interference problem has always been a headache in the industry, and cable companies can get rid of this bottleneck.

The response of wire and cable companies with security as the main market is a very practical issue. At present, concern has arisen among wire and cable companies. At the same time, the attention of security companies has also risen.

Cable companies that have been in contact with and cooperated with before are not cable companies with security as the main market. Some have cable television as their main market, while others use exports as the main market. They only care about how much the product is sold and how much processing is required. With regard to profits, there is little concern about the adaptability or upgrading of the application companies' requirements for cables, and the separation from each other is the basic situation.

You mentioned how to deal with the problem and talked about the key core. The development of technology and market sources and applications, the cable industry is no exception. Collaborate with each other and information infiltrate each other;

The close integration of cable companies with the majority of engineering application companies is an inevitable trend in the market development. Security forums often see such discussions: Some people asked them about the interference of images transmitted by coaxial cables. What are the problems and how to solve them? Some people say that the use of twisted pair transmission, anti-interference ability, low cost; some people say that the cable, no interference, and now the price is not expensive; this is unilateral selling, no cooperation.

In engineering practice, there are cases where interference has occurred in coaxial transmission, twisted pair transmission, optical cable transmission, and wireless transmission. All of them can be solved, but there are also many people who say that your cable has problems; cable companies should have more Understand how disturbances occur and are resolved. Different transmission methods should be mutually complementary and not antagonistic. Cable companies should also pay close attention to the development of transmission methods and work closely with transmission product innovation companies.

For example, network video transmission, a conventional large-scale monitoring system, must pass through multi-level network cable + switch relay transmission; someone has developed a network coaxial cable transmission technology, can access more than 20 million HD from the line node Video signal (as well as audio, alarm, control signal), transmission distance: cable length is less than 400M92Mbps; cable length is less than 1000M74Mbps; cable length is less than 2000M30Mbps; this data is very large, in front of the old process transformation makes sense, if Cable companies feel that they still use old cables and do not buy your cable, and they are not interested in or resisted. You cannot cooperate actively. However, if you see this, it will have long-term implications for the future development of online video transmission. It should take the initiative to focus and understand, and then cooperate to develop a cable suitable for high speed, broadband and higher performance;

It is also true that cable companies cooperate with security engineering companies to jointly expose and resist counterfeit cables.

The anti-jamming of the wired transmission of video information is a concern for everyone. How should a security cable company deal with this problem?

The interference problem involving cable quality is not a major contradiction. It is mainly in the aspects of transmission environment, transmission method, construction quality, system design, etc. It is more specifically the concept of the earth electromagnetic environment, the earth electromagnetic interference, and the magnetotelluric environment. The quality of cables has a direct relationship with cable companies; several factors behind them are problematic, and even the best cables will still have interference; cable companies should not blame each other for countermeasures, but should actively cooperate to understand the real reasons. Accumulate experience and information, help new users to use well, improve the lack of cables, find new application requirements and cable innovation information; this is to do before the eyes, look long-term;

The optical cable transmission system does not need to consider the interference at all. In fact, in the engineering practice, there are a lot of complaints on the Security Network Forum, and the storm leaks out of the optical cable system. This is an unreasonable design problem for the front-end and back-end. Two issues need to be emphasized here: First, the cable quality problem is not the main cause. The main reason is the design of the system, the electromagnetic environment of the external electromagnetic environment, and the grounding everywhere not only causes interference, but also can destroy the equipment under severe conditions. Therefore, the concept of the magnetotelluric environment is proposed, and the second problem is the safety design of the security system. If the MT environment is not known, equipment grounding that is not to be grounded will inevitably cause equipment damage. In short, we must pay attention to the design of the security system.

The emergence of products such as analog high-line, HD-SDI cameras, and the impact on security cable companies?

This has a certain influence. The problem is that there are various kinds of cables, such as network cables, twisted-pair cables, coaxial cables, and optical fibers. These devices can transmit. In addition to cables, the network transmission devices include switches and general twisted-pair transmission. About 100 meters, then a switch is grounded. 100 meters of cable transmission in the security project is a small project distance, in the security project generally reach a distance of 1000 meters to several kilometers, in this case, the cable must be considered comprehensively, cable companies and application companies must be combined. Don't be obedient to selling only your own products. A good system is a collection of various transmission methods. There must be a system concept and an integrated concept. We must have a long-term vision, jointly develop the market, and we must jointly promote progress.

For products, different devices must be selected based on different transmissions. Cable companies must also pay attention to the transmission development of transmission companies. Do not ignore certain products because they have nothing to do with their own products. Today, these technologies are rapidly developing. The transmission equipment must ensure the transmission quality and meet the standards for transmission. These are the maximum transmission distances reached by the transmission cables. It is very important for cable companies to pay attention to the development of transmission technologies and their close integration. Don’t worry about this product development because it has nothing to do with me. In fact, we must see the potential of this kind of product in HD development. Once this kind of product appears, the company needs to produce a product that matches it. This is a very significant long-term. Development results.

Digitalization, high-speed, broadband, network, etc. This is the inevitable trend of future development. The traditional cable technology indicators are not suitable for some; it should be said that higher requirements have been put forward.

For cable companies, the professional level of products must be continuously improved.

In practice, we create a lot of experience. Security companies must learn more about cable companies. Cable companies must not only sell good things, they must also learn more about security companies, understand the current technological development status of security companies, integrate with the security industry, and pay attention to it. Practicality.
