2015 security hot spots worth watching
Coaxial HD market, the current three major mainstream: HD-CVI, HD-TVI, AHD have already provided a complete solution in the 720P, 1080P resolution, which also means that this year began, coaxial HD can fully support the 720P 1080P. Although there are no indications that analog HD solutions with resolutions higher than 1080P will be introduced in the future, it is not excluded that H will be introduced in the future. The 265 plan. Although the performance of the picture quality, there is a certain gap between the product quality of the current market and the high-definition network, but as the program becomes more and more perfect, this gap will become smaller and smaller.
From the point of view of technical characteristics, HDCVI adopts a new analog modulation technology, and transmission does not suffer from chroma interference in the CVBS mode. It uses 75-3 coaxial cable to ensure the reliable transmission of 720P (1080P) signals of 500 (300) meters of high-quality high-definition signals, and can provide high-definition video transmission without delay.
HDTVI has a large signal bandwidth, can accommodate more image data, can reduce overall costs, and requires less storage capacity; it can transmit distances of 300-500 meters over coaxial cable and can transmit CVBS 75 ohm simulations. Signals (similar to traditional signals); and transmission of 30/60fps 1080P and 720P signals. The AHD emphasizes brighter color separation, signal filtering, and 3D noise reduction technology. In terms of transmission distance, the coaxial transmission of common 75-3 lines can reach 500 meters. AHD can be compressed to the back end without encoding, full real-time zero delay and no distortion, and compatible with ordinary D1/960H and peripheral devices (distributor, matrix, etc.).
Comparing the high-definition network, coaxial HD is still in the new generation. It is believed that with the continuous development of technology, this gap will become smaller and smaller. Network HD is still at the forefront of the era, leading the development of video surveillance technology.
Coaxial HD market
Thanks to the low market price, the analog products (including coaxial products) in the broad sense of video surveillance are still the bulk of the market. Throughout 2013, the IP and analog sales volume was 20:80, and the sales amount was 40:60. Although the analog-standard definition market is irreversibly contaminated by the high-definition network market, in order to retain or capture more users in the low-end market, coaxial high-definition is currently slowing the pace of this change to some extent.
In the past three years, coaxial high-definition has emerged and was quickly accepted by the market. Due to its low price, recommended installation features, and better data protection, it also seamlessly interfaces with existing analog products. As far as the current market is concerned, the future of coaxial HD will replace the original SD products. Therefore, the market for this piece is still large enough, because the timely demand for analog products is declining year by year. However, due to the large amount of its own market, coaxial HD is relatively at this golden time point. Axis HD solution can not create a good market environment with the enemy, but also depends on assisting security companies to complete the conversion process to high-definition monitoring, because the previous network of high-definition technology breakthroughs, followed by analog SD price fight to the end.
High-definition coaxial high-definition, in the form of propaganda on each other is also spared no effort, has become a new competition in the field of video surveillance companies. As a product of the low-end market, the replacement of the existing SD market is the only chance for survival. However, the difficulty of dealers lies in the incompatibility of these three coaxial high-definition solutions and the price reduction pressure of network HD products, so coaxial The sales model of high-definition relying on the distribution market is also difficult for small and medium-sized manufacturers, because dealers do not know which one is the most marketable. In terms of prices, it can be seen that the prices of these three companies will be adjusted with the intensity of competition, including further price cuts to eat most of the entire analog stock market.
