The research on the selection and trade-off of analog surveillance and digital surveillance products and systems was carried out by enterprises and users, and the following main influencing factors were summarized:
Element One: Price Costs Compared with analog monitoring equipment, digital monitoring is a new thing. The introduction of new technologies and concept products is accompanied by high prices. Take the camera as an example. In the standard definition monitoring era, whether it is an analog camera or a network camera, the most widely used graphic sensor is the CCD. After entering the era of high-definition surveillance, high-definition surveillance has become very sensitive to cost factors! The higher image resolution requirements than in the past made the old image acquisition, processing, transmission, and storage equipment suddenly unable to provide support. The CCD is bulky and consumes a lot of power, which brings a huge cost to the improvement and popularization of the high-definition picture quality of the network. pressure. "It's too expensive. Don't consider it for the time being" is the voice of the vast majority of engineers, integrators, and users who are still using simulation.
However, it is gratifying that the application of CMOS sensors is changing this dilemma. Although the overall image quality is not as good as that of CCD, it has a high degree of integration, a smaller product size, lower power consumption, and lower cost advantages. Be favored. As technology matures, the price of digital products will gradually come down. Moreover, to achieve high-resolution monitoring at megapixel level, CMOS is more cost-effective, which makes the development of higher-end HD in the future. Digital monitoring is easier to implement than simulation, and the cost is relatively cheap. Of course, whether it is analog or digital, the final outcome of the game between the two will be determined by the product's price/performance ratio. Under the same application effect, whoever wins the price will win.
The second factor is that the development of the company needs to be seen from a long-term perspective. It is believed that IP video surveillance will eventually replace analog video surveillance. For those users who originally used analog cameras, forward-looking suppliers and engineering integrators have started to work out plans to help users Analog signals are converted to digital signals. Such as network video surveillance company - Axis, the company has installed nearly 3 million sets of IP video surveillance systems in the world, with 35% of the IP video surveillance market share currently sitting in the world's digital monitoring field is far ahead. The development of the digital video surveillance market in Asia is lagging behind. Take Axis global sales as an example. The situation in each major region is 50% in the Americas market, 40% in Europe, and only 10% in Asia.
China's digital surveillance market has just started, accounting for about 5%. However, with the rapid growth of China's economy, even if it is forecasted by the United Nations to predict a slower global economic growth in 2011, China’s growth rate is expected to “take a look at the worldâ€, and it is difficult for any aspiring multinational enterprise to face China. The market has taken lightly. The enterprises that have already been involved in digital monitoring in China must also sow seeds in advance so that they can fully prepare for the digital application. The vast majority of respondents said that they believe that China will become the world's largest video surveillance market.
Element 3: Party A requires “Our project has started to use digitally monitored products, but we still insist on using analog products. We recommend customers to use digital as much as possible according to the nature, characteristics, and needs of the project, but in the end, we respect the customer’s decision. "An engineering company expressed to the Security Knowledge Network." The current domestic security market is basically the Party A market, that is, the buyer's market. For manufacturers, whether to choose their own products is determined by the engineering design and construction unit and the integrator, while for the engineering contractor/integrator, users need to consider the decision. . Based on the current high cost of digital surveillance products, the vast majority of parties use analog products and mixed-module solutions. Of course, customers who do not care about prices and specify pure digital solutions, such as government agencies, are not excluded. The construction and transformation of large-scale and important projects for customers such as banks, banking, etc., in terms of long-term use, maintenance, and expansion and upgrading, choosing digital surveillance is more advantageous to them.
Element Four: Geographical Concepts From a global perspective, IP video surveillance applications mainly cover: transportation and shipping, education, retail shopping malls, government, safe cities, and medical industries. In fact, the digital system to successfully replace the analog system, the biggest factor is not the technology, but to allow the market to recognize and accept digital video surveillance. The results of surveys conducted by interviewees show that developed countries and regions are more likely to accept digital surveillance products and concepts and apply them to actual projects first. From the domestic point of view, developed areas in the east and the south and cities such as Shanghai, Guangzhou, and Shenzhen are more knowledgeable about digital products than the north and west regions. In particular, Guangshen is a major manufacturing base and distribution center for security products and digital products. Will be the first to be launched and applied; and Shanghai, as the leader in software and platform development and design, digital, especially network intelligence monitoring walk in front of the country. The situation of digital product promotion and application in these developed regions and cities is much better. On the contrary, there are still gaps in economic development between the central and western regions and the northern regions. Even the information in some localities is relatively closed, the ideas are still relatively backward, and the new things cannot be accepted at once. "Practical" and "cheap" are still the primary criteria for measuring products and projects.
Element 5: Easy to use Usually, there are many lines behind the analog video camera to transmit video and audio signals. There are also many drawbacks to the processing and management of analog signals at the back end. In the digital management platform, analog signals need to be first converted into digital signals for storage, archiving, and querying. When they are queried, they often need to be converted back to analog signals, and the analog signals are also susceptible to electromagnetic interference. Digital networks, Using digital signal transmission, the transmission process has no interference and trouble. When faced with complex requirements such as real-time queries and cross-department real-time information sharing, the inefficiency of analog video surveillance data processing is even more exposed.
If digital video surveillance systems are used, the above problems will be solved. IP video surveillance system deployment is very simple, such as network cameras can plug and play in the existing corporate network. In addition, analog video surveillance often requires 8 channels for storage. If a user wants to add another 10 channels, additional digital video recorders (DVRs) are required. The use of IP video surveillance, it makes it all very simple, as long as the plug in the Ethernet port can be handed to the background to deal with. Convenient and flexible, plug and play, and can easily achieve remote access and multi-point access, which is the charm of digital video surveillance.
