According to an investigation report on the market's understanding of twisted pair transmission products by a Chinese engineering company in December 2010 by Utech, 75% of the project suppliers have heard about twisted pair transmission products. 53% of customers are using or have tried; 21% of the engineering companies fully agree and actively adopt it. These data have increased to varying degrees compared to the 2009 survey, indicating that China's security application engineers have positively recognized the twisted-pair transmission products. So, with the development of twisted pair transmission technology, what will happen to the twisted pair products?
With the promotion of UTP, UTEPO, and other world-class twisted-pair transmission technology leaders, twisted-pair transmission products have become more and more widely used in security monitoring.
First, the product of a higher degree of integration of the current mainstream twisted pair transmitter or the main transmission monitoring of the video signal, the use of twisted pair transmitter to replace the traditional coaxial transmission scheme and part of the short-distance fiber transmission scheme or the current The main application point. The U-Pop concept of V-PAD is to transmit Video, Power, Data, and Audio audio signals over a single cable, so that all the main interface signals of an analog camera can be transmitted on a single cable. Completed on the Internet, the integration of the product has been greatly improved, which greatly facilitates the construction of the project.
Due to the special nature of using cable transmission power, the transmission distance of this kind of product is generally very close, the furthest is 300 meters at present, giving the camera 12V/1A power needs to occupy 2 pairs or more twisted pair, in the current wide There is still some distance in application, but as technology continues to advance, we will certainly see farther transmission distances, such as products over 500 meters in length.
Second, the product's intelligence is higher When our engineers use twisted-pair transmitters, they often find this thing very cumbersome to use, especially when it takes more than 600 meters to use an active twisted-pair transmitter. The old generation products always have to constantly adjust the dial switch to adapt to long-distance transmission. Take the UTP101AT/R as an example. There are 4 dial keys on the transmitting device and 4 dial buttons on the receiving end. Engineers are constructing. When used for the first time, he suffered a lot of hardships and felt that the images were always unclear, and that the construction site was in disorder and distracted. It was only after clarifying the laws that the products were found to be "stupid," but the prices were low, and the adjustments were still very stable. The labor paid was not exhausted. The second-generation product has added the “fine-tuning†function. UTP108AR-U is also an upgraded product with fine-tuning capabilities. This type of product has become more convenient in construction, but it still needs adjustment after all.
The need for human adjustment will consume labor costs, so the market is expecting a new generation of fully automated smart products. According to the current schemes provided by major chip companies, there are already a number of automatic transmission products on the market. For example, UTP Corporation's 2009 Shenzhen Amway Jinding Award Product UTP116R-U, Shenzhen LeTV and some other companies also introduced automatic gain products. Wait. As this technology is currently in the trial phase, the stability has yet to be improved, but in the future, smart products with automatic gain will definitely become the mainstream of twisted-pair transmission products.
Third, the installation of products is more convenient For on-site construction engineers, easy installation is a very important part of whether the product is high quality. The products designed by NVT, the top company of the industry in the industry, have no performance in terms of technological advancement and domestic products. The big difference, the main difference is the product design. NVT's product serialization has been put into place very well. The products designed are very focused on on-site installation. Large products can be racked, small products have very good installation positions, single-channel can also be assembled into 16-way architecture, so NVT's The product is a classic of the industry. The domestic enterprises started late. The founders were mostly based on electronic technology, and they still had a lesson in product organization and product installation. This brought great difficulties to the internationalization of domestic products.
We are delighted to find that domestic companies have imitated the beginning of others and reached a little bit of independent innovation. Some large companies with standardized specifications have already formed their own product systems, and they have also made rapid progress in the design of industrial structures. UTP1 series is the current domestic series. The most complete product chain. In the future, twisted-pair transmitter products will become more and more compact and modular. After all, twisted-pair transmitters are an interface product that can be small, small, fault-tolerant and can be quickly replaced, and the cost of replacement is still very low. The product is the customer's favorite.
Fourth, the product's stability requirements higher impact security engineering and security engineering designers use twisted-pair transmission of an important factor is the product's stability. Frequent concerns about instability in twisted-pair transmitters, concerns about major projects using twisted-pair transmitters, failures, fear of lightning, fear of anti-jamming performance, and fear of surge immunity. In many people's view, twisted-pairs are mostly shieldless when transmitting signals. Are unshielded cables undisturbed? Exposed wires are not subject to induced lightning attacks. These concerns are very high. Normally, it is also a problem that must be solved by the enterprises that produce products. On the one hand, as the technology matures, the stability of the product will be greatly improved, and the means and methods for designing the product such as lightning protection, anti-jamming, and waterproofing will become more scientific. In terms of the current product, the overall stability There has been a qualitative leap forward from five years ago, and the failure rate of sold products is also declining year by year. On the other hand, the experience accumulated by installation engineers over the years will provide a relatively safer environment for twisted-pair transmission systems. It is a factor that ensures the stable operation of the product.
Fifth, the signal transmission distance further 5 years ago, the transmission distance of the twisted pair transmission products is an important concern of the market, it seems that although the transmission distance is very important, but the market's attention is obviously decreasing, one of the reasons is 80 More than % of the projects are within 600 meters, and 600 meters or less is relatively small; the second reason is that there are optical fiber transmission schemes above 600 meters, so a twisted-pair transmitter capable of transmitting 1200 meters is enough. In fact, twisted-pair transmitters can be transmitted farther. According to the technical solutions Eutelphane currently masters, transmission of 2000 meters is a very conservative distance. Is there such a market at such a long distance? Compared to optical fiber, it is so far. Is there an advantage in distance? Overall, it is always a good thing that the signal transmission distance is farther. Using a solution to solve a project is far more painful than solving with multiple solutions. The most exciting thing is the video surveillance signal transmission distance of 2000 meters. If the use of twisted-pair transmitters can definitely save a large amount of cost, with this driving force, it will certainly lead to the emergence of products of 2000 meters or more in the near future. Let us wait and see.
